Arduino Guess the Frequency Game
This is a bit of an odd one, but I was asked to put something musically related together as a game to get in the spirit of the season, so I thought something along the lines of an Arduino adjustable tone generator with the aim being the player has to tune it by ear to … Continue reading Arduino Guess the Frequency Game
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
XIAO MIDI Synth Board PCB – Part 2

I am not responsible for any damage to expensive instruments! These are the key tutorials for the main concepts used in this project: XIAO SAMD21, Arduino and MIDI 3V3 MIDI … Continue reading XIAO MIDI Synth Board PCB – Part 2
XIAO MIDI Synth Board PCB
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
Analog IO Board PCB – Part 2
This is the build guide for the Analog IO Board PCB. 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 the key Arduino tutorials for the main concepts used in this project: Simple Potentiometer Breakout Arduino Multi-pot Mozzi FM Synthesis … Continue reading Analog IO Board PCB – Part 2
Analog IO Board PCB
A number of my synth projects require the use of potentiometers. A while back I made a relatively simple stripboard pot breakout, but it isn't particularly reliable. This PCB is a pot breakout that can be used in various ways - either direct, with a 4051 multiplexer, or with an SPI MCP3008 expander. It also … Continue reading Analog IO Board PCB
