  • I've Created a MIDI Modulation Controller You Wear Around Your Neck

I love playing keyboard “live” so I found that “vibrato” (modulation in MIDI speak) on solo instruments is not very exciting if left on permanently. I needed a way to bring in the modulation like vocalist do on a long note, but without needing to take my hands off the keyboard.

So I created a small box with a “micro:bit microcontroller” inside. This has a USB connection to a Windows tablet running Bome MIDI Translator Pro. The micro:bit has an “accelerometer” function built in.

As I tilt my head back from vertical, the micro:bit’s accelerometer detects the tilt and sends characters via the USB to the Bome MIDI Translator Pro. Using your “Serial” feature I can pick up the characters and translate them into “Control Change 1” (modulation) MIDI messages.

I have other projects:

1/ To emulate the function of “Second Touch” as used on theatre organs. By playing a “loud note” ( Note On Velocity above 80 ) will generate another note on a different MIDI channel with a different tone. This is brilliant to bring out the melody line with a single keyboard.

2/ A “Crescendo Pedal” again as used on theatre organs. This uses a “foot volume pedal”. The effect is to bring in more “stops” ( in theatre organ speak)  i.e. more sounds in unison with the original on different MIDI channels. As the pedal is pressed further, more MIDI sounds are played. The sounds used get progressively “louder” and “fuller” as the pedal is pressed.

I have more projects using Bome MIDI Translator Pro if anyone is interested or want more info on the 3 mentioned.

Sounds interesting, Harvey! I’ve seen something similar using the Numark Orbit controller that has an accelerometer as well. I think there are also some MIDI Fighter devices with this capability. The Numark Orbit has a wireless dongle which makes it even nicer. I don’t think that product is still in production, however. I had to get one used on eBay.

Thanks for sharing!
