Porting Synth_Dexed to the Raspberry Pi Pico #RaspberryPi #RaspberryPiPico @diyelectromusic

For a while, Kevin has wanted to get Synth_Dexed up and running on a Raspberry Pi Pico. It is the library written by Holger Wirtz for use with the Teensy microcontroller, and the core synth engine used for MiniDexed.

This is how I got everything up and running although it is too early to know if this is a worthwhile activity or not!

And the performance isn’t what anyone would call stellar… I can currently manage 4-note polyphony if the sample rate is dropped.

  • Part 1: Building Synth_Dexed for the Pico.
  • Part 2: Assessing the performance and analysis of the Pico audio library.
  • Part 3: MIDI and some basic usability (finally).
  • Part 4: More MIDI; Bank and Voice loading; SysEx support; and USB-MIDI.
  • Part 5: Details of how to build the hardware.

Seeing as MiniDexed exists for the Raspberry Pi and MicroDexed exists for the Teensy, PicoDexed seemed the obvious choice!
