Raspberry Pi 400 Cyberdeck MIDI Player

I've finally gotten myself a Raspberry Pi 400 computer. I've wanted one for a while to use as a MIDI player for my Lo-Fi Orchestra. The idea is that eventually I might be able to run it without a large display, but instead use something like the Adafruit Cyberdeck and a PiTFT display (or similar) … Continue reading Raspberry Pi 400 Cyberdeck MIDI Player →

Nano Audio Experimenter Sheild PCB

This takes the Arduino Nano Mozzi Experimenter Shield PCB and swaps out three of the pots for the optional use of the following: MCP4725 DAC. SSD1306 display. IO links for an analog multiplexer. This is in addition to the remaining three potentiometers, the MIDI interface and the audio filter output. Warning! 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 →

Arduino PSS-680 Synth Editor- Part 1

I'm still exploring the range of Yamaha (and a few others) keyboards from the 80s with interesting synth chips. So far I've looked at the YM2413 and the PSS-170. I also have some YM3812s and a PSS-460. But today I'm looking at the PSS-680 which has a YM3420 in it, with the eventual aim of … Continue reading Arduino PSS-680 Synth Editor- Part 1 →

Simple MIDI Serial Monitor – Part 3

This is a follow-up to the following posts: Simple MIDI Serial Monitor - which shows how to use SoftwareSerial as a MIDI port to allow monitoring over the default serial port. Simple MIDI Serial Monitor – Part 2 - which shows how to use SoftwareSerial as the monitoring serial port instead. This post takes one of my … Continue reading Simple MIDI Serial Monitor – Part 3 →
