This module is a waveshaper that allows for PWM-like sounds used with non pulse waveforms. It's an easy build that uses external CV controls and plays well with other modules.
The board features PC mounted pots for less wiring, and mounting holes for flexibility in panel layout. There are Eurorack and MOTM power connecters. Notes for 15V builders are included in the build documentation.
Audio Demo 1: Ramp, triangle and sine waves, first the unaltered waveform and then going through the pulsewave with the controls all at 12 o clock.
Audio Demo 2: Ramp into pulsewave with LFO and envelope modulating the Hi/LO controls. Then triangle wave with different settings in two different registers.
Audio Demo 2: Triangle wave into a VCA into the pulsewave, an LFO slightly modulates the HI setting of the pulsewave. I'm manipulating the decay time of VCA's envelope, and then the hi/lo settings of the pulsewave..

Boards are available now. Price for 1 PCB is $8.
Unfinished eurorack
panels are available for this project, they are 6HP and cost $8 each.
There is
more information here about panels. If you're interested in drilling your own panel for
this project, feel free to use my
drill guide. That image should be printed at 300dpi for proper
scaling.
