The following knobs are used for determining what each of the two modulators should modulate.
Note that these knobs are bi-polar, which means that if a knob is in the middle position, no modulation is applied. If you turn a knob either to the left or to the right, an increasing amount of modulation is applied to the parameter. The difference is that if you turn a knob to the left, the waveform of the modulator is inverted.
Mod:A can modulate the following parameters of either oscillator:
Use this if you want Mod:A to offset the pitch of osc:A, osc:B, or both.
Use this if you want Mod:A to offset the index start position of osc:A, osc:B, or both.
Use this if you want Mod:A to affect the harmonic content of osc:A, osc:B, or both.
Mod:B can modulate the following parameters of either oscillator:
Use this if you want Mod:B to affect the motion speed of osc:A, osc:B, or both.
Use this if you want Mod:B to change the output level of osc:A, osc:B, or both.
Use this if you want Mod:B to offset the cutoff frequency of filter:A, filter:B, or both.
Use this if you want Mod:B to change the total amount of modulation from Mod:A.
