Midi Controller

Rain Receiver is actually a midi controller but just by using sensor. Uno is tricky because it not able to use the “midiusb.h”. the midi signal is hard to recognise even with the hairless. I could use the Standard Firmata with Max plugin but the value of the potentiometer is not stable, I attempt to add a ”potThreshold” but don’t know how to modify the Standard Firmata.

In this case, I have to switch to Leonardo or Micro. And buy some potentiometer as well.

I need to download the “midi monitor” on MAC

This project needs more reference.

Format

A moving midi controller, using the same parameter to control the move, but then I’ll need a controller to control the midi controller.

Exterior

the box probably needs to use plastic but not iron(too heavy), or wood(not stable, even through wood still needs the laser cut) maybe the acrylic board.

Component

6-8 knobs for potentiometer, 4 or 8 buttons, a slider or two? Maybe a LDR?(but how to map the LDR to midi signal??- maybe a button to active the LDR, and a light to show of the LDR is turn on or off, and when using the LDR is the same logic to map in the live. But is the LDR need a cover?) A arcade joystick potentiometer for controller the 360 degree values like the surrounding sounds.

Boards/Chips

Arduino Leonardo / Pro micro. Multiplexer

Code

with the modify X3 version the buttons and potentiometers are finished but still don’t know how to add the slider and the joystick.(for the Ableton live mapping part actually is not a problem, just need to map to the X and Y, the circle is just a appearance. So it is important to get the X and Y parameter from Arduino and transfer to the midi format.)
