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 →

Pi Pico Keypad MIDI Step Sequencer

As soon as the Raspberry Pi Pico came out accompanied by the Pimoroni Keypad, people started making MIDI controllers with it. So far, most of the ones I've seen have used the USB MIDI library from Adafruit for Circuit Python, but I wanted to get some "real MIDI" out of it, so I've hooked one … Continue reading Pi Pico Keypad MIDI 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 →

LOLShield MIDI Step Sequencer

One of the things I always do when I get a new LED matrix style display is run Conway's Game of Life on it, so having recently played with some MIDI step sequencers, I thought it time to put the two together. This is the result. In a follow-up post, I add some simple MIDI … Continue reading LOLShield MIDI Step Sequencer →

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 →

Arduino MIDI Step Sequencer

This adds MIDI out capability to the Arduino Tone Step Sequencer. Here it is driving a Roland MT-32 paired with the Arduino Light Mozzi Generator – Part 2. https://youtu.be/nOx_mO8V0uY 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!
