One thing that requires a bit of clarification is the notion of
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!
LFOs, pitch-bend and MIDI note number modulations are bipolar. If you are used to electronics/Modular
speak, it is equivalent to say that the LFOs are always "AC-coupled" instead of "DC-coupled".
Another thing worth noting is that the modulation amount of the last patch in the modulation matrix is
