XIAO ESP32-C3 MIDI Synthesizer – Part 6

Expanding on my previous posts, I thought it might be interesting to see how I might be able to add some additional IO to the MIDI Synth. This is an exploration of some options there. Part 1 - Getting started and getting code running. Part 2 - Swapping the ESP32-C3 for a SAMD21 to get USB … Continue reading XIAO ESP32-C3 MIDI Synthesizer – Part 6 →

XIAO USB Device to Serial MIDI Converter

Having recently revisited the CircuitPython USB to Serial MIDI Router as part of XIAO ESP32-C3 MIDI Synthesizer – Part 2 it reminded me I didn't really have a simple Arduino USB device to serial MIDI for the XIAO. So this is filling that gap. Warning! I strongly recommend using old or second hand equipment for your experiments. … Continue reading XIAO USB Device to Serial MIDI Converter →

XIAO ESP32-C3 MIDI Synthesizer – Part 5

So I was somewhat guilty that I'd replaced the XIAO microcontroller in the last couple of parts to get USB MIDI, so in this one I put the original ESP32-C3 back in and now have a version of Part 4 for serial MIDI. Part 1 - Getting started and getting code running. Part 2 - Swapping the … Continue reading XIAO ESP32-C3 MIDI Synthesizer – Part 5 →

XIAO ESP32-C3 MIDI Synthesizer – Part 4

In Part 2 I looked at how to add USB MIDI to the XIAO MIDI Synthesizer and in Part 3 I looked at some of the properties of the SAM2695 synth chip itself. This post combines the two into a relatively simple, but playable, synth. Part 1 - Getting started and getting code running. Part 2 - Swapping … Continue reading XIAO ESP32-C3 MIDI Synthesizer – Part 4 →

XIAO ESP32-C3 MIDI Synthesizer – Part 2

After an initial play with the XIAO ESP32-C3 MIDI Synthesizer the first thing I wanted to try was to swap out the ESP32-C3 for something else, just to see what could be done. Part 1 - Getting started and getting code running. Part 2 - Swapping the ESP32-C3 for a SAMD21 to get USB MIDI. Part 3 - … Continue reading XIAO ESP32-C3 MIDI Synthesizer – Part 2 →

XIAO ESP32-C3 MIDI Synthesizer

I quite like many of the XIAO boards, so when I got an email announcing the XIAO MIDI Synthesizer I went off to buy one and take a look. This uses the Dream SAM2695 MIDI device, which is a General MIDI instrument in a chip. I have a couple of devices that use this chip, … Continue reading XIAO ESP32-C3 MIDI Synthesizer →

ML Synth Tools XIAO SAMD Synth

Having listed out a few Arduino Audio and MIDI Frameworks and having spent some time recently with the XIAO SAMD21, I thought I'd take a closer look at the ML Synth Tools XIAO synth. Important Update: It would appear that the ML_SynthTools and samd21_mini_synth repositories have been fairly significantly updated since I wrote this. I've tried … Continue reading ML Synth Tools XIAO SAMD Synth →

Arduino Audio and MIDI Frameworks

I've been collecting bookmarks for interesting Arduino audio projects for a while now, and having now played with the XIAO SAMD21 I started looking back over my list for other things to try. One thing that occurred to me is that there are a now a number of more powerful audio frameworks available for a … Continue reading Arduino Audio and MIDI Frameworks →

Arduino MIDI Multi Pot Controller

Once again, I've realised that whilst I've now completed a number of multi-potentiometer MIDI controller projects, I haven't actually written up a non-multiplexed, multi-potentiometer controller. This projects fills that gap! Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! These are … Continue reading Arduino MIDI Multi Pot Controller →

XIAO SAMD21, Arduino and MIDI – Part 8

This post brings together some custom PCB designs for use with a Seeedstudio XIAO SAMD21. Other 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 and using them for MIDI. Part 3 - Mozzi FM synthesis using … Continue reading XIAO SAMD21, Arduino and MIDI – Part 8 →
