Phase modulation with ratios
Start with the ratio patch as above but listen to the sine and cosine outputs of the
center oscillator instead. Bring up the PHASE INDEX 1 and PHASE INDEX 2
controls (making sure all other modulation controls are down.)
You should be able to hear the ratios or modulated arpeggios through the center
oscillator but as phase modulated timbre changes instead of directly (listening to the
outside oscillators).
If you bring up the PHASE CV controls (carefully, less than halfway) of the outside
oscillators then they will cross modulate each other resulting in high harmonic
content, even if you are just listening to the center oscillator.
If you bring up the cross modulation too high it will disintegrate into noise, but just a
little can really bring life to a patch.
A nice variation is to set the left oscillator to free and low mode so it becomes an
unsynced lfo (you may want to remove any modulation that may have been plugged
into the V/OCT RATIO jack). If you are still listening to the sine cosine pair your patch
should gain a large stereo element.
When you have done all this try also listening to the saw and cosaw outputs of the
center oscillator, you will also get a large stereo field but with much more harmonic
content.
