recently i was making some of my own presets with the miniscope but kept hearing what sounded like amp modulation on my sound. i checked all the modulation sources and turned them off but still the sound was moving in volumn. it wasn't until i started turning off osc's one at a time. appears that when multiple osc's are used some cancelaton goes one especially if you detune one of them. is this normal or is there a work around to get a full bass sound on every keystroke.

thanks

Subject: Yes, phase cancellation is normal in a synth

Either use "Oscillator Sync" or keep the oscillators more closely in tune.

What you're noticing is phase cancellation, which happens on any synth where the oscillators are actually attenuating and cancelling some of the sound.

Try different levels of detune... for the 'super phat' sounds, try using one oscillator, or all of them in sync (can't remember if MiniScope has that or not).

Also running the MiniScope through Obsidian (now AnaFX) Tubulator makes the sound HUGE :D

Subject: Amplitude variance is normal

For the last twenty years that volume change has been my only real problem with great analogue bass sounds. You get something fat in unison with a little detune and at some stage during a held bass note you'll hear the level build up or drop off. It's a function of all the oscillator waveforms eventually lining up. The only thing I've ever been able to do to keep the sound but lose the cyclic level change is to use a bit (or a lot) of compression.

At least that way you don't have to compromise on your patch.
