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 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 →

Duppa I2C MIDI Controller – Part 4

This is revisiting my Duppa I2C MIDI Controller this time using a Waveshare Zero format device. Part 1 - getting to know the devices and testing them out. Part 2 - adding MIDI to the LED ring and I2C encoder. Part 3 - adding normal encoder, plain potentiometer, and endless potentiometer control. Part 4 - revisits the idea with … Continue reading Duppa I2C MIDI Controller – Part 4 →

Arduino PCF8574/8575 MIDI Controller

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 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 →
