Today I read the Micron manual on my commute into work and I read about the self oscillating 4 pole moog filter emulated on the Micron and I thought I'd see what I could make of that. So I turned off all the oscillators, turned up the resonance and played about with the filter frequency until I was left with a quite lovely organ like sound. Didn't see that coming! I tweaked the amp envelope a little and I couldn't stop playing church organ sequences, very atmospheric. Definitely sounds best if you avoid the higher registers.
One thing I found was that I needed to add 1% of noise otherwise I got no sound, there is possibly a good reason for this, if anyone knows then feel free to drop a comment!
Anyway, here is the patch, Oscillatorless:

The reason you needed to set the noise to a minimal amount is probably that the Moog filter model on the Micron is not really self-oscillating in the strict sense of the word, i.e. it does not start to oscillate on its own when you crank up the resonance, but it needs some input to start the filter oscillation. Once the filter oscillation is stimulated, it will continue to oscillate on its own, though. There are actually very few VAs which have truly self-oscillating filters.
ReplyDeleteThanks Chris, very interesting!
