I suggest that each user posts here a sound design tip. In this way we can all benefit from this list. It doesn't matter whether it's an old one - there are always new people to sound design
I' ll go ahead and post two:
1. To make a sound more full try mixing the oscillators at different volumes, i.e. VCO1 = 6, VCO2 = 5, VCO3 = 7.
2. You can make very animated pulse waveforms by applying an LFO + inverted LFO to the pulse width. To do that you need a CP-251 to invert the waveform. Triangle waves work best for me.
Go ahead
