XIAO SAMD21, Arduino and MIDI – Part 4

One of the nice things about the SAMD21 based microcontrollers like the XIAO is the embedded USB support.  Whilst it can make the uploading a little, er, interesting, it also allows for the building of USB devices.  This post looks at how to turn the XIAO into a USB MIDI device for more MIDI routing. …

XIAO SAMD21, Arduino and MIDI – Part 3

In this post I wire up the DAC and start up Mozzi using my Arduino Multi-pot Mozzi FM Synthesis on the Seeedstudio XIAO SAMD21 board (previously known as the Seeeduino XIAO). Previous parts in this series: Part 1 - Introduction to the XIAO SAMD21 and some projects to get started. Part 2 - Looking at accessing …

XIAO SAMD21, Arduino and MIDI – Part 2

In this post I look at what is involved in getting multiple MIDI interfaces connected to the Seeedstudio XIAO SAMD21 boards (previously known as the Seeeduino XIAO). Previous parts in this series: Part 1 - Introduction to the XIAO SAMD21 and some projects to get started. Part 2 - Looking at accessing additional serial ports …

XIAO SAMD21, Arduino and MIDI

I've had a few Seeedstudio XIAO SAMD21 boards (previously known as the Seeeduino XIAO) for a while but haven't really done much with them.  I had a brief go with Circuitpython to build a CircuitPython USB to Serial MIDI Router but that is all so far.  Having been inspired by a recent post on the …

SAMD51 USB MIDI Multi-Pot Mozzi Synthesis

When I left my Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 3 I had the following: Mozzi synthesis on the Trinket M0 board (that uses the SAMD21 Cortex M0+ processor core at 48MHz). Four note polyphony. USB device functionality - it can be controlled via MIDI over USB from a PC. USB host functionality - …
