Last week I created some new Sound Effects for an upcoming collaboration project I'm working on. I can't tell you details yet, but keep an eye out :) Earlier this week I used the Roland SH-5 and today I used the ARP 2600 to make some new and unique sweeps, twirls, whooshes, modulations and so on. I usually just patch around and turn knobs while recording. Then when I think I have enough I start selecting the good parts and neatly trim then down. It is very boring work actually, but in the end it is rewarding to hear them back in a track, knowing that you made everyone from scratch :)
