Arduino Tone Polyphony – Part 4

In this final (for now) part of my Arduino Tone Polyphony project I'm returning to part 2 which was creating a stand-alone, full 12-note polyphonic tone keyboard with an Arduino Uno and committing it to an Arduino Shield using a proto-shield. Warning! I strongly recommend using old or second hand equipment for your experiments. I am … Continue reading Arduino Tone Polyphony – Part 4 →

Arduino Tone Polyphony – Part 3

Having achieved my full 12-note polyphony both over MIDI and using built-in keyboard encoding, the last part of this experiment was to see what range was possible using this method for tones. This project manages four octaves with 12-note polyphony and tuning that, whilst isn't perfect, isn't too bad either. https://youtu.be/Vf4GcZHLVJQ Warning! I strongly recommend … Continue reading Arduino Tone Polyphony – Part 3 →

Arduino Tone Polyphony – Part 2

There were two enhancements to my Arduino Tone Polyphony project I was keen to explore. One was to expand the MIDI range of notes and one was to "build in" a keyboard. I have managed to create an experimental version that can support four octaves over MIDI, but tuning needs some work, so I'm not ready … Continue reading Arduino Tone Polyphony – Part 2 →

Arduino Tone Polyphony

I've been reading about the Oskitone 555Poly which looks like a lot of fun. It is a fully polyphonic sound generator based on one 555 oscillator circuit per key, each one individually tuned to the note you want it to play. Unfortunately my budget for making is unlikely to be able to justify getting one … Continue reading Arduino Tone Polyphony →

Lo-Fi Orchestra – Procession of the Nobles

The Lo-Fi Orchestra presents the Procession of the Nobles from Rimsky-Korsakov's opera-ballet Mlada. This is a piece that I really don't hear played very much, but has a lot of appeal to me. This really features the quartet of the Arduino MIDI Multi-Tone Module on the brass fanfares. This has been programmed in from scratch … Continue reading Lo-Fi Orchestra – Procession of the Nobles →

Arduino MIDI Multi-Tone Module

I've not done anything with the Arduino's built in tone() for a while so thought I'd revisit something I've wanted to explore for a while - Arduino tone() polyphony! But not of the sort I explored in the Arduino Multi MIDI Tone Module which stacked up several Arduino MIDI Tone Modules together. Instead, I wanted to … Continue reading Arduino MIDI Multi-Tone Module →

Arduino Tone Step Sequencer

I've been meaning to build a step sequencer for a while. This is device that you can use to repeat a simple sequence of notes over and over and build up interesting patterns. In the next part I'll be adding MIDI out. https://youtu.be/oCHl-sRMuUM These are the key Arduino tutorials for the main concepts used in … Continue reading Arduino Tone Step Sequencer →

Arduino Light Tone Generator

Having played a little with my 556 Timer Light Theremin I thought it time to get an LDR attached to an Arduino. A common extension to the Arduino Tone Generator is to replace the potentiometer with a light dependent resistor (LDR) to give a fun instrument that responds to light in a way similar to how a … Continue reading Arduino Light Tone Generator →

WS003 – Drums and Touch

This is the next of my worksheets collecting together a number of related projects with a single list of parts and a suggested "building order". This time all relating to touch interfaces or percussive projects. This worksheet links together the following projects: Arduino Relay Bolero Arduino MIDI Relay Drumkit Arduino MIDI Relay Servo Drumkit Instant … Continue reading WS003 – Drums and Touch →

WS002 – MIDI In, MIDI Monitors and Effects

This second worksheet looks at projects related to receiving and processing MIDI messages, providing a single list of parts and a suggested "building order". This worksheet links together the following projects: Simple MIDI Monitor Simple MIDI Monitor - part 2 Arduino MIDI Note Monitor Arduino MIDI Channel Monitor Arduino MIDI Tone Module Arduino Multi MIDI … Continue reading WS002 – MIDI In, MIDI Monitors and Effects →
