https://diode.zone/videos/watch/41742940-14ca-4781-8fc5-3c5ad1c17275 In part 3 of the DIY Raspberry Pi Pico MIDI to CV converter project I've added another two CV outputs (giving a total of 4) and four sliders via an MCP3008 8-channel 10-bit ADC. The sliders control attack, decay, sustain and release of an envelope generator which I have hooked up to the Werkstatt's filter cutoff CV input (via CV output 3 on the Pico). This allows me to have independent envelopes for the VCA and VCF and really opens up the sonic potential of the synth. 00:00 Demo of a few envelope settings and second CV output. 00:24 Track starts =========================== Gear Used: Raspberry Pi Pico with 2 MCP4725 DACs and separate slider and MIDI interface boards Moog Werkstatt-01: the intro bass and arpeggio in the second half Korg NTS-1: delay and reverb for the Moog Elektron Model:Samples: MIDI control of the Wekstatt on track 6, everything else on tracks 1-5 =========================== The Set Up: The Elektron Model:Samples is set up to sequence MIDI notes on track 6. These are sent via DIN MIDI to the Pico, which generates a gate signal and pitch voltage for the Moog Werkstatt-01 on CV 1. The analogue readings from sliders 1,2 and 4 are translated to attack, decay and release time and slider 3 to sustain level of the envelope generator and sent out to the Moog Werkstatt via CV 3 (CV 2 and 4 aren't populated in this demo). Finally, the output of the Werkstatt goes to a Korg NTS-1 for a bit of reverb and delay. =========================== More info, code and schematics can be found here: part 1: https://axwax.eu/electronics/raspberry-pi-pico-as-midi-to-cv-converter/ part 2: https://axwax.eu/electronics/a-second-cv-out-for-the-raspberry-pi-pico-midi-to-cv-converter/ part 3: in progress Tue, 20 Oct 2026 13:37:42 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://diode.zone https://diode.zone/lazy-static/avatars/61b689b7-84d5-43c7-9fa8-e63a7fd1d952.png https://diode.zone/videos/watch/41742940-14ca-4781-8fc5-3c5ad1c17275 All rights reserved, unless otherwise specified in the terms specified at https://diode.zone/about and potential licenses granted by each content's rightholder.
