Multi-Mode MIDI Step Sequencer – CDR Format – Part 2

This post is the second part of my series to document the building of a "CDR format" (CD Rack Format) panel version of my Multi-Mode MIDI Step Sequencer. Part 1 detailed the build and testing of the panel. This part updates and enhances the Multi-Mode MIDI Step Sequencer code to run on the panel. https://youtu.be/YmQ7j-tDudkContinue reading Multi-Mode MIDI Step Sequencer – CDR Format – Part 2

Multi-Mode MIDI Step Sequencer – CDR Format

When I put together the Multi-Mode MIDI Step Sequencer it was with an eye to creating some kind of "modular" style panel format.  This post documents the building of a "CDR format" (CD Rack Format) panel version. This part details the build and testing of the panel. Part 2 will update and enhance the Multi-Mode MIDI … Continue reading Multi-Mode MIDI Step Sequencer – CDR Format

Pi Pico PIO Poly Tone Step Sequencer – Part 2

In this project I've added some basic IO to the Pi Pico PIO Poly Tone Step Sequencer. https://youtu.be/a5Mkd0wnbzs 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 tutorials for the main concepts used in this project: MIDI, MicroPython … Continue reading Pi Pico PIO Poly Tone Step Sequencer – Part 2

Pi Pico PIO Poly Tone Step Sequencer

In the next part of my messing around with the Raspberry Pi Pico PIO polyphonic tones, I've paired it up with my Pi Pico Keypad MIDI Step Sequencer using my Pimoroni RGB Keypad. In part 2 I add some MIDI controllers. https://youtu.be/JJSOUhSP038 Warning! I strongly recommend using old or second hand equipment for your experiments.  I … Continue reading Pi Pico PIO Poly Tone Step Sequencer

LOLShield MIDI Step Sequencer – Part 2

I wanted to experiment with different scales and tempos with my LOLShield MIDI Step Sequencer but naturally didn't want to keep having to recompile and redownload sketches onto the Arduino, so some kind of control was in order. However the LOLShield uses all the IO apart from RX/TX, which are used for the MIDI, but I … Continue reading LOLShield MIDI Step Sequencer – Part 2

Arduino MIDI Mux Step Sequencer – Part 2

By way of completing this initial look at multiplexing potentiometers, this is how I used a Sparkfun 16 port multiplexer in my Arduino MIDI Step Sequencer. https://youtu.be/MiPyJrPlmVs Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments.  I am not responsible for any damage to expensive instruments! These are the key Arduino … Continue reading Arduino MIDI Mux Step Sequencer – Part 2

Arduino MIDI Mux Step Sequencer

If you keep using single IO ports of the Arduino for your controls you reach the limits pretty quickly.  In terms of analog IO that is six inputs for an Uno and eight for a Nano.  The solution is relatively straightforward however, use a multiplexer. This project inserts a 74HC4051 eight port multiplexer into the Arduino … Continue reading Arduino MIDI Mux Step Sequencer
