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 →

VS1053 and MIDI Revisited

Right back when I first started looking at the VS1053 I looked into the MIDI mode, which can be enabled in hardware, but at the time I opted for a software route to using the boards with MIDI. This post finally takes a fresh look at the range of VS1053 boards available and how to … Continue reading VS1053 and MIDI Revisited →

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 Pi USB MIDI Device PCB

One thing missing from a MiniDexed build is USB device support. The Raspberry Pi will act as a USB host to USB devices, but the MiniDexed can't be plugged into another USB host. Some versions of the Raspberry Pi (notably the zero and 3A+) support USB On The Go (OTG) which means they can act … Continue reading XIAO Pi USB MIDI Device PCB →
