I strongly recommend using old … Continue reading Nano Audio Experimenter Sheild PCB →

3.3V Serial MIDI THRU

I have a need to route MIDI to several Raspberry Pi boards at the same time, so I've hacked together a variant of my MIDI Matrix Patch Bay to give me a 3.3V level serial MIDI THRU interface. I've used it for my 8-way Raspberry Pi V1 MiniDexed in the following video. https://makertube.net/w/g8rw9XtF4Z377dsANRu5Yr Warning! I strongly … Continue reading 3.3V Serial MIDI THRU →

Arduino PSS-680 Synth Editor- Part 2

Following on from Part 1, this post looks at combining several of my previous projects to allow me to control the synth of a PSS-680 from a set of potentiometers. Part 1 - Goes into the detail of the MIDI implementation for the PSS-680 and how to handle the SysEx messages from an Arduino. https://youtu.be/aRfAQvwq8lc … Continue reading Arduino PSS-680 Synth Editor- Part 2 →

Arduino MIDI Foot Pedal for Peavey Vypyr Amp

I was asked to take a look at a Peavey Vypyr amp to think about how the foot pedal for it works. This is a set of links and notes by way of recording what I found out, and some initial experiments with an Arduino. Warning! I strongly recommend using old or second hand equipment … Continue reading Arduino MIDI Foot Pedal for Peavey Vypyr Amp →
