A little synth experiment inspired by Ploytec's little πλ² (or PL2) box. It produces mostly "squary", chiptunesque sounds but also fat and bassy brassy square pads.
A single wavecycle consists of two pulse half-waves. The pulse width of each half-wave can be modulated independently. The pitch of the second half-wave can be adjusted relative to the played pitch (fifths and octaves work well).
The "complex" mode lets the first half-wave produce amplitudes above zero in the positive range and the second goes below zero into the negative range.
The priciple can be observed on an oscilloscope (and sometimes the waves look nicer than they actually sound ).
Manually modulating pulse widths. 2nd half-wave's pitch is doubled;
The same with "complex" setting:
1st half-wave's pulse width and 2nd half-waves pitch (x4) modulated with separate lfos:
The patch has a lowpass filter which can be envelope modulated.
Yes, there can be settings that produce lots of aliasing. But hey, chiptunes
And, as before, when the patch refuses to play, lower the polyphony (currently it's 6 voices).
