This is a minor update to my Arduino MIDI Filter to allow it initialise patches as well as filter MIDI if required. 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 tutorials for the main … Continue reading Arduino MIDI Filter – Revisited →

My first experiment uses a Raspberry Pi Pico (in "sawn-off" mode - see later!). In this follow-up post, I turn the phone … Continue reading Vintage Phone MIDI Controller →
