JC Pro Macro (V2) MIDI Controller

I was exchanging some messages with Jeremy Cook on Twitter about Arduino tones on Leonardo compatible boards (i.e. those driven by the ATmega32U4) and that lead to a conversation about his latest crowd-funding effort for a Pro Micro-based "Macro" keypad and rotary encoder. One thing led to another and he very kindly sent me one … Continue reading JC Pro Macro (V2) MIDI Controller →

“Bare Metal” Raspberry Pi Synth

The Raspberry Pi is an "SBC" - a single board computer, whilst the Arduino (and the Raspberry Pi Pico for that matter) is a microcontroller. Simplistically a single board computer is, well, what most people would think of when they think about a computer - a board (with or without a case!) that you plug … Continue reading “Bare Metal” Raspberry Pi Synth →

Arduino MIDI Rotary Encoder Multi-Track Step Sequencer

Now I have the option for multiple colours for my step sequencer displays, I thought it might be interesting to start experimenting with a "multi-track" step sequencer. https://youtu.be/oQc1IVoJLeQ 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 … Continue reading Arduino MIDI Rotary Encoder Multi-Track Step Sequencer →

Arduino MIDI Rotary Encoder Step Sequencer – Part 3

I am continuing my experiments with different ways of visualising a step sequencer and this comes from from a suggestion by Twitter user @AxWax - using a NeoPixel ring. https://youtu.be/u4WNbgCWvds 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 … Continue reading Arduino MIDI Rotary Encoder Step Sequencer – Part 3 →

Arduino MIDI Rotary Encoder Step Sequencer – Part 2

In my last post, I mentioned other display options for my rotary encoder step sequencer. To be honest, I wanted an excuse to use some "LED bars" with a rotary encoder, so this post is more by way of an excuse to play rather than a serious option, but in reality it actually works quite … Continue reading Arduino MIDI Rotary Encoder Step Sequencer – Part 2 →

Arduino MIDI Rotary Encoder Step Sequencer

I'm thinking about other applications for a rotary encoder and one thought was to support a multi-step, step sequencer with just a single knob, so this takes the Arduino MIDI Step Sequencer and recodes it to use the rotary encoder and 7 segment display described in Arduino MIDI Rotary Encoder Controller. Here are some links to … Continue reading Arduino MIDI Rotary Encoder Step Sequencer →

Arduino MIDI Rotary Encoder Controller

I've finally gotten around to having a play with rotary encoders. It has been on my "to do" list for a while, so I thought I'd start with a rotary encoder version of my Arduino MIDI Button Controller which can select a voice and send the corresponding Program Change message out over MIDI. https://youtu.be/uxT_RQs1MXM Warning! I strongly … Continue reading Arduino MIDI Rotary Encoder Controller →

PC USB-MIDI to MIDI Revisited

This is another take on the PC USB to Arduino Serial MIDI once again taking the Pro Micro I used in part 2. Recall that the Pro Micro board (not to be confused with the Arduino Micro or the Pro Mini) is an Arduino Leonardo compatible smaller board, using the ATmega32U4, which means it has a … Continue reading PC USB-MIDI to MIDI Revisited →

Arduino LDR MIDI Piano

I always meant to go back to my Arduino LDR Pianola and extend it to more notes, but so far haven't quite got there. But this projects uses a multiplexer to link up eight LDRs to an Arduino and use it as a simple "keyboard" MIDI controller. https://youtu.be/Ne6J-a7ACwE Warning! I strongly recommend using old or second … Continue reading Arduino LDR MIDI Piano →

Arduino Touchscreen Mini MIDI Tenori-On

The next experiment with my cheap touchscreen is to re-create my mini Tenori-On, but this time with more "buttons". https://youtu.be/kqZEotcWZY8 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 Arduino tutorials for the main concepts used in … Continue reading Arduino Touchscreen Mini MIDI Tenori-On →
