DIY Raspberry Pi Pico MIDI to CV converter pt.2: Dual CV output, distance sensor & Neopixels
In part 2 of the DIY Raspberry Pi Pico MIDI to CV converter project I've added a second CV output, a distance sensor as a modulation source and a Neopixel ring to visualise its output. This allows me to control the LFO rate of the Moog Werkstatt-01 through hand gestures.
00:00 Demo of the distance sensor and second CV output.
00:30 Track starts
===========================
Gear Used:
Raspberry Pi Pico with 2 MCP4725 DACs, Sharp distance sensor, Neopixel ring and MIDI interface
Moog Werkstatt-01: the bassline
Korg Monotron Delay: Filter cutoff and delay for the bassline
Elektron Model:Samples: everything else
===========================
The Set Up:
The Elektron Model:Samples is set up to send out 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 CV1.
The distance sensor’s analogue output is visualised by the Neopixel ring as well as sent to CV2, which is connected to the Werkstatt’s LFO FM input to control the speed of the LFO which is modulating the cutoff frequency of the bassline.
Finally, the output of the Werkstatt goes to a Korg Monotron Delay, which is used to further filter the bassline and to add delay to it.
The LFO is set up to modulate the filter cutoff frequency.
