Pete Midi's video: Behringer K-2: amazing PWM hack - solderless

Behringer K-2: pulse width modulation (PWM) for the MS-20 clone without modification of the hardware? Here is my fun project for a non-invasive solution. 00:12 idea & setup 06:07 flexible EG demo (mono, no FX) 07:13 synchronized LFO jam (with Model D and BCF noise) 09:00 slow LFO jam (with Model D and BCF noise) Gear used: Behringer K-2, Model D and BCF2000 fader controller. QuNexus keyboard connected to Raspberry Pi 3B+ running QMidiArp. Recording with Tascam DR-2d (synths and microphone), mixing with Ableton Live 10 (Reverb, Echo, MicroTonic). Notes: The EG and LFO midi control signals were generated with QMidiArp, which was also used for Model D sequencing and K-2 arpeggios in the LFO jams. All tracks were recorded with Tascam DR-2d. The EG demo just shows the unprocessed mono signal of the K-2. For the LFO jams I also recorded the BCF2000 fader movement with a microphone (DR-2d) and mixed it with the synth signals in Ableton Live where I also used the built-in Reverb and Echo effects. I could not resist to add some very sparse beats from the MicroTonic, mainly bass drum.
