The modulation destinations are the following:
1. prm1, prm2: Oscillator 1&2 parameters.
2. osc1, osc2: Oscillator 1&2 pitch.
3. ~1+2: Oscillator 1&2 coarse pitch.
4. vibr: Oscillator 1&2 fine pitch.
5. mix: Oscillator balance.
6. xmod: Oscillators cross-modulation amount. This has no effect when the off or sync mixing
modes are selected.
7. nois: Noise amount.
8. sub: Sub-oscillator amount.
9. fuzz: Fuzz amount.
10. crsh: Sample-rate reduction amount.
11. freq: Filter cutoff.
12. reso: Filter resonance.
13. attk: Envelopes attack time.
14. deca: Envelopes decay time.
15. rele: Envelopes release time.
16. lfo4: Voice LFO rate.
17. vca: VCA gain.
One thing that requires a bit of clarification is the notion of bipolar modulation source. Let's take an
example. We have a triangle LFO mapped to the filter cutoff, with a modulation amount of 30. If the
cutoff is set to 80, the actual value of the cutoff will oscillate between 50 (80-30) and 110 (80+30). On
the other hand, if we have an envelope mapped to the cutoff with a modulation amount of 20, the
cutoff will go from 80 to 120 (80 + 2 * 20), then down to 80 after the release. This is something to
remember if you want to do PWM for example. If you set the PWM modulation amount to 40, you also
have to set the oscillator parameter value to 40, so it will oscillates between 40-40 = 0 and 40+40=80.
Otherwise, it will spend half of the time stuck at 0. But this makes things nicer for vibrato, tremolo,
wah-wah or growl effects!
