Pico Touch Board Audio

I wanted to go back to my Pico Touch Board PCB Design and see if there was a way to make it more stand-alone. The original design was to make it a MIDI controller, but that isn't the only option. https://makertube.net/w/tADSyrPrUdR1mx7yKRXZTC Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Pico Touch Board Audio →

Forbidden Planet “Krell” Display – MIDI CC Controller – Part 2

This revisits my Forbidden Planet “Krell” Display – MIDI CC Controller using my Forbidden Planet “Krell” Display PCB with a Waveshare RP2040 to create more of a "all in one" device. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! If you … Continue reading Forbidden Planet “Krell” Display – MIDI CC Controller – Part 2 →

Forbidden Planet “Krell” Display EuroRack Module

This project uses my Forbidden Planet “Krell” Display and the Forbidden Planet “Krell” Display PCB Design but with some slight variations that means it could be EuroRack mounted with a control voltage (CV) input. This is a DIY module only for use in my own DIY system. Do NOT use this alongside expensive modules in an … Continue reading Forbidden Planet “Krell” Display EuroRack Module →

Waveshare RP2040 Matrix MIDI Monitor

Following on from my ESP32C3 OLED Mini MIDI Montor and Waveshare Zero, Pimoroni Tiny, and Neopixels this project uses a Waveshare RP2040 mini Matrix display. This is largely the same pinout as the other Waveshare boards, but includes a 5x5 programmable LED (i.e. neopixel-like) matrix. https://makertube.net/w/cdxAJJvsqsPKrzVg6xWodD Warning! I strongly recommend using old or second hand equipment for … Continue reading Waveshare RP2040 Matrix MIDI Monitor →

Raspberry Pi Pico Capacitive Touch

I've now done a number of projects using capacitive touch, using a range of methods from native IO handling to the use of the MPR121 and off-the-shelf boards. Typically native IO methods require testing a response between a signal on one IO pin being received on another, with the timing of that response affected by … Continue reading Raspberry Pi Pico Capacitive Touch →

Raspberry Pi Pico Multi MIDI Router – Revisited

After publishing the details of my diy proto-board version of my Raspberry Pi Pico Multi MIDI Router I got into a conversation with @VE7FIM on Twitter about MIDI boards for the Pico and they very kindly offered to design and build a dual MIDI interface board for me for my Pico. This was back in … Continue reading Raspberry Pi Pico Multi MIDI Router – Revisited →

Raspberry Pi Pico SysEx “Librarian”

I've seen a few dedicated units for sending and managing patches for older synths and whilst they look really neat, I thought it would be worth me having a go and seeing what I could do myself. This is my first attempt at pretty much the simplest hardware "patch librarian" I could imagine - it … Continue reading Raspberry Pi Pico SysEx “Librarian” →

Pi Pico MIDI Button Voice Select

This is an alternative take on my Arduino MIDI Button Voice Select this time combining it with both my Pi Pico MIDI Button Controller with a hint of the CircuitPython USB to Serial MIDI Router too. The end result is a voice and bank selector that will also act as a USB MIDI to serial MIDI converter. In … Continue reading Pi Pico MIDI Button Voice Select →

Pi Pico MIDI Button Controller

Having played with MiniDexed a little now, I really wanted something that could select the different banks of voices for me. This is how I've used a Raspberry Pi Pico as a set of "bank select" switches, but the switches could be used to send any MIDI change control messages. https://youtu.be/if0iKuHCkE4 Warning! I strongly recommend … Continue reading Pi Pico MIDI Button Controller →
