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

MT32 Clumsy MIDI Program Changer and Filter

Having used my MT32-Pi (in fluidsynth mode) with an updated Arduino MIDI Filter in the Lo-Fi Orchestra – Jupiter from The Planets I decided to combine them with my Arduino MT-32 Program Changer try to create an add-on board for my Clumsy MIDI interface to allow a self-contained unit that: Can set the patch number (voice) for the MT-32 … Continue reading MT32 Clumsy MIDI Program Changer and Filter

SAMD USB MIDI Multi-Pot Mozzi Synthesis

When I left my Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 3 I had the following: Mozzi synthesis on the Trinket M0 board (that uses the SAMD21 Cortex M0+ processor core at 48MHz). Four note polyphony. USB device functionality - it can be controlled via MIDI over USB from a PC. USB host functionality - … Continue reading SAMD USB MIDI Multi-Pot Mozzi Synthesis

Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 3

So, I've performed some optimisations for my polyphonic Trinket USB MIDI Multi-Pot Mozzi Synthesis and think this is probably where I'll leave the code for the time being.  You can get an idea of what it can do in the video below. https://youtu.be/piz4varsgXg Warning! I strongly recommend using old or second hand equipment for your … Continue reading Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 3

Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 2

This is a first go at getting polyphony running on my Trinket M0 USB Mozzi synth.  It is very much a work in progress though as I've just not managed to get the right balance of the different aspects of the system running together yet.  But I thought I'd pause and report what I have … Continue reading Trinket USB MIDI Multi-Pot Mozzi Synthesis – Part 2

Arduino Top Octave Generator – Counter Experiments – Part 2

This is an incomplete experiment, but I wanted to test the principles from Arduino Top Octave Generator and Arduino Top Octave Generator – Counter Experiments in practice a little more. You may recall the basic idea here is to generate 12 tones using an Arduino and then use binary counters to divide them by 2 several … Continue reading Arduino Top Octave Generator – Counter Experiments – Part 2
