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!
