This is a synth IO board based on my XIAO MIDI Proto PCB for the Seeed Studio XIAO series of microcontrollers. It can support four or eight potentiometers, depending on the XIAO board being used. Build Guide: XIAO MIDI Synth Board PCB – Part 2 Warning! I strongly recommend using old or second hand equipment for … Continue reading XIAO MIDI Synth Board PCB

XIAO SAMD21, Arduino and MIDI – Part 7
This post looks at the possibilities of using I2C peripherals with a Seeedstudio XIAO SAMD21 and the XIAO Expansion Board. The projects should work with either USB MIDI or serial MIDI via an external MIDI module. Note: There is just one project described at present, but others will be added to this post as they … Continue reading XIAO SAMD21, Arduino and MIDI – Part 7
XIAO SAMD21, Arduino and MIDI – Part 6
This post looks at a series of relative straight forward MIDI control projects using the Seeedstudio XIAO SAMD21 and the XIAO Expansion Board. The projects should work with either USB MIDI or serial MIDI via an external MIDI module. Other parts in this series: Part 1 - Introduction to the XIAO SAMD21 and some projects … Continue reading XIAO SAMD21, Arduino and MIDI – Part 6
XIAO SAMD21, Arduino and MIDI – Part 5
This part looks at USB host device support on the SAMD21 based XIAO. This means that rather than plug the XIAO into something else, like a computer, instead other things, like USB MIDI keyboards and controllers, can be plugged into the XIAO. Unfortunately this wasn't as smooth and successful as other posts, but there still … Continue reading XIAO SAMD21, Arduino and MIDI – Part 5
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. … Continue reading XIAO SAMD21, Arduino and MIDI – Part 4
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 … Continue reading XIAO SAMD21, Arduino and MIDI – Part 3
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 … Continue reading XIAO SAMD21, Arduino and MIDI – Part 2
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 … Continue reading XIAO SAMD21, Arduino and MIDI
MiniDexed TX816 – Part 6 – Pico MIDI Router and TX816 IO Code
It's been a while since finishing the MiniDexed TX816 Mechanical Assembly and I had a bit of a distraction recently rebuilding my Lo-Fi Orchestra, but I've also been tinkering with the code for the TX816 IO panel and router. This post looks into a bit more detail what it is all doing. Posts in this series: … Continue reading MiniDexed TX816 – Part 6 – Pico MIDI Router and TX816 IO Code
Raspberry Pi Pico MIDI Note Balancer
One use for my Raspberry Pi Pico MIDI Splitter is as a way to get pseudo polyphony from a range of monophonic sources. I've called this "note balancing" from the idea of "load balancing" online systems - sharing out the "ask" across a number of devices. In a similar way, this can take requests to play … Continue reading Raspberry Pi Pico MIDI Note Balancer
