Klee Sequencer (Part 2)

I visited my local electronics shop again today to pick up some more parts for the Klee Sequencer. I also look for some nice led holders and found these ones. The only problem though is that they were wider than the holes that Bridechamber put in the front panel. I don't know what kind of led holders Scott uses, but they need to be very tiny since these ones were the smallest I could find. Well I think these look neat since they are shiney like the rest of the front panel components I selected.

The only scary thing was that I needed to drill holes in this very nice front panel. I think the standard holes were 6 millimeter and for the led holders I selected I needed to drill 8 millimeter holes. Well luckily there is room enough for that. I did a trial first on the Yusynth Noise and Random module I build before. There was still a led holder missing on that as well. I also found out that There are 5 more leds going on the front panel than I anticipated. I only looked at the step position leds, but there is also a clock led and bus leds. Well the electronics shop had enough in stock :)

In the picture on the left you see the result. Looks nice doesn't it? Well I like it anyway. I did have some trouble by the way to get the plastic piece in that holds the led in place in the metal casing. If you look closely in the picture on top you see a little black thing sticking out of the led holder. That has to go all the way in actually to secure the led. And I needed to apply quite some force on to that. Maybe I'm doing something wrong, but at least the won't go anywhere anymore now. I'll pick of 5 more leds and led holders somewhere soon and finish it. Now back to the PCB's :)

Klee Sequencer (Part 1)

Today I got the first parts for the Klee Sequencer. I only got some resistors actually and not even all of them. My local electronics supplier was out of 100K 1% resistors. So they had to order them for me. They didn't have time to get the rest yet. There was a choice to make in the design for 5 Volt or 10 Volt trigger voltages. I chose the 5 Volt. I think my stuff will trigger on that. If not I will have to change some resistors later on. This is something to look at when you want to build a Klee sequencer for yourself. In the picture on the left you see the digital PCB by the way.

In the picture on the right you see the analog PCB. I'm also missing the 100K resistors for this one, but then lots of them were stated as 0.1%. My local electronics store actually never heard of that :) I need to see if I can get them somewhere on the Internet. If you have tips please let me know. There is also a possibility to hand match the resistors from 1% types. The mounting holes in these PCB's are quite small actually what makes it difficult to get the solder flowing. But I guess I have to get used to this for this project. Maybe I should look for a smaller tip for my soldering iron.

Here is another picture of the Klee Sequencer front panel together with the PCB's. I'm now studying the building document and I'm looking for the front panel components. There is a lot of switches on there and the building document states that it is important to get quality ones for this. Bridechamber is not selling a component kit for this unfortunately, so I will have to find them somewhere else. Ah well I'm sure I'll find the brands mentioned in the document somewhere. So far this looks like a fun project. I can't wait to get it doing something useful :)

ASM-2 (Part 9)

This evening after dinner I started to test the ASM-2 main PCB. I started with measuring the power. There is a +15/-15 Volt power rail and that seemed to work quite well. Besides there are some +10/-10 Volt reference points on the PCB to use for calibrating purposes. They all looked fine to me. The power regulators got a bit warm, but not hot, so I guess the PSU is holding fine. I hooked up a connector to the common power rail to get a ground for my oscilloscope to be able to look at some signals.

I started by testing the oscillator outputs. On VCO-2 everything looked very nice. I just had to calibrate some of the wave shapers to get symmetric waveforms, but on VCO-1 I found something strange. The sawtooth looked fine and also the square wave, but the sine wave and triangle were completely screwed up. In the picture on the right you see the waveform I got from the triangle wave. This looks more like a distorted saw actually. It clips on +15 and -15 Volt as well and it was supposed to be 10 Volts peak to peak. So time for some trouble shooting.

I started to study the schematics of the oscillator and found quickly that the base waveform is the saw and the other waves are generated from that one. The sine wave is generated from the triangle, so the problem had to be in the wave shaper circuit for the triangle wave. It is based on two diodes and a TL084. After a measuring and comparing to the other VCO I found that on one of the outputs of the TL084 I got no output signal. At first I thought the TL084 was broken, but when I wanted to swap it I felt it was warm. I looked under the PCB and found the problem. A tiny drop of solder was between the output of this IC and a through hole on the PCB. It was so tiny that I missed it on the two earlier inspections I did. But I could measure it.

After I removed it this was the result. On the picture on the right you see a very nice triangle wave. And after this also the sine wave was fine. When I tell it like this it sounds like this was an hour work, but actually it took me the whole evening to find this. But afterwards it is always a gratifying feeling when you solved a problem like this. The next thing is to calibrate the VCO's and test the rest of the modules. I hope that goes a bit smoother. At the moment I'm checking how to hook up everything, but I think I need some more crocodile clamped wires.

AVRSynth 32 (Part 3)

This afternoon I worked some more on the AVRSynth with my daughter. We actually managed to finish the PCB. It was not very exciting since only the connectors were left to solder. Strange thing is that for the small connectors there were two different kinds. One was a regular connector and the other one just a header connector. Ah well it works just the same and eventually it is inside the case so nobody will notice. After that the PCB needed to be mounted on the bottom of the casing. I drilled four holes in the bottom and used nuts and bolts to fasten everything.

After that we started mounting the panel components. First the ones on the rear. Not much there. Just an audio output connector on a jack, a connector for an external 12 Volts DC power supply and a midi jack. Strangly enough I also couldn't find the nuts and bolts that should have come with the midi jack I guess. But well I have enough of those. Then we continued with the front panel. I found the 8 potmeters as stated earlier in the bag with all the potmeters for the ASM-2. It looks like Elby just tossed everything together. Ah well now that I know it is OK.

We started to mount the potmeters. I found out quite quickly that I had to shorten them by sawing a piece of the shaft. Since there are metal it was not a very easy job. While it was doing this my daughter lost concentration and left. But we decided that I would finish this job. I also had a problem later on getting the knobs on. I had to find a special tool to fasten them. The screw is very tiny and is of the Hex/Allen/Imbus type. (I'm not sure what the correct English name is). I finally found one that barely fitted and was able to secure them. The next thing I found out is that the holes for the led holders are too small. So I will have to drill them larger I'm afraid. There is more DIY to this kit actually than I expected. But after this I stopped and will continue again when my daughter feels like it again.

ASM-2 (Part 8)

Last week when I had to stop soldering because it was leaking again, I decided to pick up another job. I took the ASM-2 cabinet down from my modular desk and started to mount the jack connectors to the front panel. There are a lot of them I can tell you. It took me a while before I found an effective method to fasten them and get them straight at the same time. Another thing that puzzled me is that I had 4 stereo jacks and the rest was mono. So I E-mailed Laurie from Elby Designs about this and he got back to me on this.

One turned out to be for the AVRSynth32 actually and I know where to put the other three now. Here you see the whole thing from the back. All the jacks are switchable in order to be able to make the ASM-2 semi-modular. If you look closely at the front panel you can see that besides all the input jacks there is also written where it gets its normalized input from. It took me a while to figure this out by the way. But now I understand it and it makes perfect sense. In the picture you can also see that I can easily take the back of because it is fastened with some magnets.

There are still lots more front panel components left to mount. After the jacks I started sorting and counting the pot meters. And there I also found the 8 missing pot meters for the AVRSynth32. So that problem is solved as well now. Most potmeters are 100K linear, but there are some other ones as well. I'm going to focus first on finding out where they should go. Besides that of course a lot of knobs, and some turn switches, leds, and switches. I'm still struggling a lot with the documentation of the ASM-2, but I'm sure that in time I will understand it all.

After I sorted all the components I decided I did enough mounting of front panel components and looked the PCB's up again from my stack of unfinished electronics. The first thing I had to do was to mount two heat sinks on the power regulators. I got them long time ago from Elby Designs but just didn't mount them yet. After that I started to read again through the documentation to see what power I should apply in able to start testing the PCB's. It turned out that the main PCB needed +24 and -24 Volts. So I put my lab power supply to this and did the famous smoke test. Well no smoke :) So all is set to start testing this PCB. I hope everything works because error seeking will be a pain in the ass on this one :)

Modular Progress Overview

Since I'm working a lot now on my modular project and I only showed you some PCB's and loose panels I thought it would be nice to post a little overview of the modules I have finished now. In the bottom of the picture on the left you can see the Yusynth filter modules I build and the Wogglebug. On top are three modules I bought on E-bay. On the left is a MOTM-120 Sub Octave Multiplier that adds subharmonics, next to that a MFOS Quantizer and next to that the Oakley Noise and Dual filter module that I used to test my other filter modules.

In this picture you see the two MOTM 900 and 950 Power supplies that I build. And also the VC-LFO that I repaired earlier. It has an Oakley front panel, but is actually a MFOS. I do plan to build an Oakley one and swap panels somewhere in the future. On the right you see the Yusynth Random module I build with noise generator and sample and hold. I still haven't fastened any module in the cabinet yet, since I'm still not sure where everything should go. I need to make some kind of plan for that I guess.

And maybe you spotted this front panel in a previous post as well. Here you see it together with the PCB's that go with it. This will become a Klee sequencer from Electro-music.com. It looks really great in this circular setup. I got this front panel from Bridechamber and it was designed by Thomas White. I studied the documentation for this project last week and I ordered all the PCB components. Hopefully they will arrive on Monday and then I can start building this beast :) I can't wait to see it working. This project is the most complex module I build so far. But we all do need a challenge don't we :) I'll keep you posted on the progress as always of course.

Chinese Limestone in the Cinema

I'm still working in the cinema to improve stuff as well. My speakers stand on needles to get clearer sound, but we put thick carpet in the cinema and those needles didn't really do their job any more, since they just disappeared in the carpet resulting in the speakers touching the round anyway. So I started looking for some nice solid and heavy stuff to put under them. Finally we found a nice solution in these Chinese limestone tiles. We found them at a garden specialist. I can be psychological of course, but I'm under the impression that it sounds way better already :)

Oceanography played on Artic Mist Podcast 186

Last week I sent out a whole bunch of promo CD's to radio stations that played my music in the past. And my record label Groove Unlimited did the same. So I hope to get some airplay the coming weeks. Last week the title track from my new album OceanoGraphy was played on the Spanish Artic Mist Podcast #186. It is a very nice show that plays good music, only my Spanish is not so good :( So if you know Spanish it would be great if you could let me know what Jorge said :). You can find the podcast on this URL: http://articmist.podomatic.com/ Look for show #186.

PC Trouble Fixed

I had a very annoying problem with the second PC in my studio. This is not my main audio recording PC, but a PC that I use for video stuff, mastering stuff, sample editing and also some editors for synthesizers are running on it. It is nice that I can do stuff on there that doesn't interfere with recording. But recently it became very slow and after a while it completely froze. It lost it BIOS settings on restarting. I was thinking it was time for a new one, but I decided to have a look first. So I detached all external USB and firewire connections and started removing PCI and PCI-e cards on by one. Suddenly when I removed one of my USB PCI cards it worked fine. So this card probably messed up the PCI buss on the main board. Well I'm very happy that I can use it normally again :)

Yusynth (Part 13)

Today I finished the Yusynth Fixed Filter Bank module. All I had left to to was solder all the PCB wiring to the front panel. As you can see it are quite some wires. I decided to make two separate cable trees with two separate colors to keep the overview. There is still one thing I need to sort out. It seems that the bridechamber front panel is designed for some kind of modification since it has an input potmeter with dry/wet on it and also a bypass switch. Those are not incorporated in the original design by Yves. I will have to look that up.

I decided to first to finish it as Yves has intended so that I can test its functionality. In this picture you can see the other side of the PCB, were you can clearly see the potmeter and switch that are not connected yet. You can also see how far I had to put the two brackets out to be able to mount the PCB on them. On the rear you see two tie raps that actually make sure the PCB doesn't hit the bracket. That could cause a short circuit maybe or at least some unwanted behavior. You can also see that jack is still missing. I haven't received my package from bridechamber yet with the missing nut.

After the wiring was done I tested it again with the noise module. It worked right away. There is no calibrating that needs to be done. I just put all the potmeters on 0 to get none of the input signal to pass and then turned up the potmeters one by one to see if that particular band was passed through. And well they all worked like a charm. Also the odd and even outputs are funny. There you get only half the the bands on the odd and the other half on the even output. I can't think of an application for that yet, but I'm sure it will come in handy sometime. Well another module finished. And at the moment that is all the Yusynth modules I have front panels for now. So I'll have to work on some other project first now untill I get new stuff from Bridechamber.

Yusynth (Part 12)

I did some more work on my Yusynth project. In the picture you see the finished PCB of a Fixed Filter Bank. I ordered this module as a complete kit from Bridechamber. It came in a nice box with all the necessary components. And I can tell you there are a lot of capacitors in there. They are all different so most time went in looking up the right ones. But I think I managed but I won't be sure until I finalize and test the module of course. This PCB is by the way also a lot larger than the other modules I build. It was a bit more difficult to mount it on the two brackets.

Well here you can see how I solved it. I left some space between them and the bottom one is hanging only on one potmeter, but it feels firm enough. And later on the PCB itself will hold everything together I guess. You can also see that I mounted all the front panel components and started wiring them. As usual I started first with the ground loop. You can also see that one jack is missing in the right bottom corner. The funny thing is that the Switchcraft jack normally comes with a mounting nut, but the one I got didn't have any thread in it. So it didn't hold much.

I asked Bridechamber to send me a new one with the next shipment. After this I started with the wires on the PCB. And there are a lot. But when I was just getting started unfortunately it started to leak again in my studio :( And it leaked exactly over my head so I had to stop. I'm getting so tired of this. I hope we can get this over with any time soon. Well in the mean time I started to make some lists of components that I needed to order for some other PCB's I have laying around. I don't have to be bored for the coming months I guess. I'll keep you posted on the updates.

My First TV Interview (German/Deutsch)

During the Electronic Circus event I visited in Bielefeld last year I was asked to do a TV interview. It was broadcasted in the Bielefeld region but now it is also available online. The interview was taken by Stefan Erbe who also moderated the event. Since he is German and the TV audience as well we decided to do the interview in German. I hope you can understand that :) Well have fun.

Yusynth (Part 11)

Today I worked some more on my YuSynth project again. I started finishing up an ARP4072 clone VCF famous from the ARP2600. Yves provides three options to build it either based on 2SA798, 2N3906 or more common BC557 transistors that need to be hand matched. I described earlier how I wrote the measured values down on a big piece of paper. Well in the picture you can see this. Most modern multimeters have a possibility to measure the HFE factor of transistors. And just put the transistor is and read out the value. I barely could make the necessary 6 matched pairs. But I managed.

After that I soldered the transistors to the PCB and started on the wiring. Again it was quite similar to the other two Yusynth filter modules I build. It is nice that Yves keeps the same logic in all his designs. Saves a lot of puzzle time :) You can see an empty IC sockeet on the PCB. There was supposed to be a LM3900, but it seems like I forgot to order it before, or just couldn't find it. This morning I tried to order one, but the minimum order value was 25. Well they are very cheap so I did it anyway. So I have 24 spares now. Ah well I'm sure I'll need some in the future.

Here is a picture of the finished module. I could test it of course because the LM3900 is missing. Same goes for calibrating. You can see this one has a 1V/Oct input as well. I can't wait to actually play a melody on a self oscillating filter actually. But first I want to finish up building the modules. I have quite a pile of stuff lying around for over a year that I really need to finish, if only it was to clean up the piles and to make sure I don't lose track of everything. Or even worse lose parts. What frustrated me though is that Bridechamber didn't have front panels for the Yusynth VCO. I really would like to build some Oscillators to make some music on them. So I started looking for another solution. But I couldn't find anyone who makes them. But I did find Schaeffer AG in Germany.

Schaeffer is a company that makes front panels from aluminum. They have a nice piece of software on their website that you can download and install. From that software you can design you own front panels and even order them online directly. So I designed my first front panel in MOTM style and ordered it. It will take about two weeks before it arrives and I'm very curious how it will turn out. It isn't cheap by the way. But the letters are engraved and painted to I'm sure it will look very professional when I didn't screw up ;) I'll let you know when it arrives. If this works I will make more for sure.

Yusynth (Part 10)

I also had a very productive afternoon. I actually finished another Yusynth module. Well almost but I will get to that later. I worked on another filter module this time a Minimoog VCF also called transistor ladder filter. This is of course a copy of the famous Moog Minimoog filter design. It is build around two CA3046's and 6 BC547 transistors that have to be matched in pairs. In this picture you can see the PCB where I already soldered all the wires on again. Behind it is the front panel with all the front panel components mounted already. I did this long ago already. So all I had to do today is wire those to the PCB.

But first I needed to drill the holes in the bracket that is attached to the front panel. I told you before that the steel that the bracket is made of is very hard and I couldn't drill holes in it without breaking something. Well here is the drill that I bought that solved that problem. I got it quite cheap at a building material store and it is actually very good and solid. I have it standing in my garage now on my other work bench. There I do all mechanical stuff. If you look in the right on the picture you can also see a Ferrari Radio Controlled car. I enjoy driving those too, but it has been a long time. But I usually work on that sort of stuff on this work bench.

OK back to the filter module :) Wiring this thing was quite easy, since it looked almost the same as the previous filter module I build. The only problem is that I was missing one mounting nut for one of the potmeters. You can see the hole for it and the loose wiring in the picture on the left. I already asked Scott from Bridechamber to ship it with the recent order I did. So I hope to get it soon. This potmeter controls the CV2 input. So it is not really a problem since I can easily test the module with the other two CV inputs. I will mount the potmeter as soon as the nut arrives.

I used the same method to test this filter module. And it was working right away. I did need to do some calibrating on the potmeters on the PCB again to get it to self-oscillate. But other than that I encountered no problems on this one. It does sound very different though from the EMS filter. Much warmer and softer even the tone you get from the auto oscillation is softer. Well that was supposed to happen :) So all's good. I have another working filter module. I think that was enough DIY modular work for today. So now I'm going do to some other stuff. Hopefully I will have time soon to finish some more stuff. I'll keep you updated of course!

Yusynth (Part 9)

This morning I finished another Yusynth module. This time it is an EMS clone filter also called diode ladder filter. You can see the diodes on the left top corner of the PCB. The values of these diodes are critical and need to be matched. You can measure the voltage drop over the diode. Typically that would be 570-590 mV. But I had to select 14 that where within a range of 3 mV of each other. I did this by measuring them and writing the value on a big piece of paper and then put it on that value. Then the next one and so on. Until you end up with 14 on one spot or just one above or below.

I had the PCB ready already, except for the diodes. So after matching them I soldered them to the PCB. After that I started with the wires for the front panel components, leaving them long enough to be able to reach every front panel component later on. And then I started doing the wiring that connect the front panel components together. You can clearly see this in the picture on the right. Here you can also have a good look at the bracket that will hold the PCB later on. Bridechamber came up with a great idea for that. Just use the potmeters on the front panel to hold it in position. I wanted to use blank wire btw for the ground, but for some reason the electronics shop where I usually get my stuff from just doesn't have that anymore. Well no disaster but blank wire is always easy for hooking up the ground of the oscilloscope later on while testing.

In the picture on the left you see the finished module from the back. Now you can see why I always leave the wires on the PCB so long. In this way you can nicely bundle them together so that it becomes a nice cable tree. Is that important? Uhhhh no not at all. but it just looks better ;) On the bottom you can see the screw connector that I use for the power now. I actually works quite well. I just ordered some female MOTM style power connectors from Bridechamber that I will attach to this connector so that I can easily hook them up to the MOTM power distribution boards.

After that it was time for some testing. After the usual smoke-test I hooked one of the inputs up to a noise generator from an Oakley module. The cut off potmeter did its work quite nicely, so the filter worked, but on the resonance potmeter I didn't really get any noticeable result. So I started to check my wiring and measure if it did what it was supposed to and it did. But no result. So I started to look at the schematics and when I was just doing that I read a note from Yves that this could happen. It had to do with one resistor that determines the range for the resonance. It had to be changed from 680K to 220K. Well I didn't have a 220K but I soldered two 100K's in series to get 200K and that did the job nicely.

After I changed the resistor it started to auto oscillate as well. And man does it sound nice on that :) I hooked it up to an LFO module to generate some nice sound effects with it. In the picture on the left you can see the finished module from the front. As you can see it even has two audio inputs and the frequency and resonance of the filter can be controlled with CV signals. You can even tune the auto oscillation to do 1 Volt per Octave, so that it becomes a real oscillator. Yves says it will track over a span of 3 Octaves. But you need to calibrate this with a trim potmeter. I haven't tried this yet. I will do that in a later stage. To be honest I don't think that I will ever use it like that . But it is nice that it can. All in all another nice result this morning. Let's go to the next one :)

AVRSynth 32 (Part 2)

After dinner today I went back to my modular desk for some more soldering. I asked my daughters if they wanted to join me in the studio since my wife had to go away and they were quite happy about it. Here you see a picture of me that my daughter took when I was soldering a whole bunch of diodes. And yes I'm wearing glasses. My eye sight is actually fine, but they have prism glasses that make it easier to focus. When I'm working long time my eyes don't get tires. And since there is not that much light down stairs my eyes have to work harder anyway. During soldering I tried to explain to my daughter also how a diode and a capacitor works. She says she understands it, but it is a bit difficult for me to believe. But I will try and keep explaining stuff to her. She seems to be very interested.

When we were busy my youngest daughter came to the studio as well. Dressed up as Minnie Mouse with the ears and all :) Isn't it sweet? Well now my oldest daughter is starting to explain to the youngest one what everything is on the PCB. I think that is so cool.
Well after that we continued to solder all the capacitors to the PCB. We could not find one of the capacitors but when I reread the documentation it turned out that this one needed to be soldered to the bottom of the PCB just like the resistor we couldn't find earlier.

Here is a picture of how far we got today. As I said before my daughter is quickly loosing concentration. So the PCB still is not finished. You can also see some drawings that I made while trying to explain what everything does. It is really fun for me to since my whole school period is passing by me :) And even though I used to hate it back then now I think it is fun. Life is weird right. I still haven't counted the potmeters on the ASM-2 by the way. So I still don't know if they are missing from the AVRSynth. Ah well I can't do everything at the same time. I'm doing a lot already I think.

After soldering the girls wanted to jam a bit on some synthesizers. Here you see them play on my Korg M3. Today they discovered Karma and how much fun that is. It didn't sound very harmonious, but it was nice that they played without fighting over it. That is harmonious as well right? :) They were quite lucky too because with all this fun I forgot the time and they were in bed half an hour later than usual. I have seen a lot of trick to stall before then go to bed, but this one was even new for me ;)

Yusynth (Part 8)

Today I finished my first Yusynth module. I started this project long time ago, but I picked it up again. The module I worked on is a dual module. It has a noise generator with pink and white noise and it also has a random and sample & hold module. Here you see the PCB in front where I soldered all the wires on first. And in the back you see the front panel I got from Bridechamber with the front panel components already on there and also the bracket where the PCB will be mounted on. If you look closely at the PCB you can also see a transistor in a socket. This transistor is easily swappable this way and that was necessary to later on select a transistor that creates the best noise :)

Soldering the wires to the front panel components on Yusynth modules is quite easy. Yves gives very nice wiring schemes on his website. I mounted a little screw connector on the PCB for the power. Since I don't have any MOTM style power connectors I just screwed the power on the power distribution board. Here you see the finished module, only the led is still hanging loose. I need to find a nice led holder to mount it on the front panel. After hooking the power up I first did the elementary test for smoke and hot components and that all looked fine.

After that I hooked up the module for testing. First of all I tested the noise sources directly on the audio and swapped some transistors. But actually I didn't really hear a difference. Both sources sounded great to me. After that I hookup the module to the VC-LFO I repaired earlier. I used it as an oscillator actually. And also the Random and Sample & Hold worked fine. Then I tested the external input and external clock. And almost boring that worked as well. So I have a fully functional Yusynth random module now. If you are interested in this module. You can find more information about it here: http://www.yusynth.net/Modular/EN/NOISE/index.html

Quest For Leak Continues

Last night it leaked again. When my wife looked in the studio this morning because it rained quite heavy last night and there was water again in one of the buckets. So it leaked again. I immediately called the constructor and he came right away again. It was dry when he came, but we put a couple of buckets water in the hole and it started leaking again after a while. So now at least we are quite sure it must be still coming from this same place. But the frustrating thing is that you don't see anything happening at all.

The constructor tore down even a larger part of the wall to make room for an even bigger patch. This time though we will not remove the old one, but just put it over it. It has to stop one day. I'm very tired by now of this. You just can't leave the house when you know it is going to rain. Well in this picture you can see how far our wall is destroyed now. But I'm sure that will be fixed again. Lets first fix the problem. Hopefully tomorrow they are going to apply the new patch. Until then I can only hope it will stay dry. I will keep you posted as always on the progress.

Terry Hawke Interview Online

Last night I did a very nice interview with Terry Hawke on his Halloween special for his show on Harborough FM (HFM). It was broadcasted on radio and also on the webstream. We talked a bit about Halloween to start with, but after that we talked about my new album release, my relationship with the Word Wildlife Fund and also about the future projects I'm working on. It was a very nice and relaxed interview that you can still listen to in case you missed it. I saved a copy on my website with kind permission of Terry and HFM. You can find it here along with some older interviews I did:
