Arduino MIDI Channel Monitor

Whilst messing about with MIDI drums at one point it would have been really useful to be able to check which MIDI channels had messages, so I thought it would be useful to have a simple MIDI channel monitor. The idea is that you have 16 LEDs, one for each MIDI channel, and if any … Continue reading Arduino MIDI Channel Monitor →

LOLShield MIDI Waterfall Display

This builds on the Arduino MIDI Note Monitor with a slightly different take to the Wemos MIDI LED Matrix making use of a "LOL Shield". LOL in this case stands for "lots of LEDs" - in this case a grid of 14 x 9 - and is a fun way to get your Arduino lighting up as … Continue reading LOLShield MIDI Waterfall Display →

Wemos MIDI LED Matrix

Building on the ideas from the Arduino MIDI Note Monitor this project uses an LED matrix, which is an 8x8 grid of LEDs. You can get these as shields for the Arduino, as individual units, as "backpacks" (i.e. modules to plug-in and use) and a whole variety of forms. Each will have a corresponding library to … Continue reading Wemos MIDI LED Matrix →

Arduino MIDI Note Monitor

This project shows you which note is being playing, within a single octave (white notes only!), by lighting up a different LED for each note. I develop more sophisticated LED visualisations in Wemos MIDI LED Matrix. The Arduino MIDI Channel Monitor shows you which channels are being used. https://youtu.be/0oSYtyVBxfE Warning! I strongly recommend using an old … Continue reading Arduino MIDI Note Monitor →

Simple MIDI Monitor – part 2

This is a repeat of the Simple MIDI Monitor but using a home made MIDI receive circuit on breadboard and then stripboard. https://youtu.be/ZmuelybXtzY 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 … Continue reading Simple MIDI Monitor – part 2 →

Simple MIDI Monitor

This project is an example of receiving MIDI data. The simplest version of this project uses a MIDI shield that you can buy quite cheaply online. In Simple MIDI Monitor - part 2 I build a relatively simple MIDI in interface on breadboard or stripboard, but it is more involved than the few resistors and … Continue reading Simple MIDI Monitor →
