The first prototype works OK, but there are a couple things I’d like to address:
– The form factor is pretty awkward. The push buttons don’t feel very much like real trumpet valves and it’s hard to hold a rectangular box and manipulate the slider. Some additional controllers would be nice as well.
– USB midi would be preferable
– I’m not sure if the filter for the BC helps or hurts.
Here’s my plan:
– I’ll replace the Arduino Uno with a Pro Micro. The Pro Micro use the atmega32U4 which has native USB support, so theoretically it should be able to implement USB Midi
– I’ll remove the linear slider and add two joysticks, which will give me 4 continuous control dimensions and two switches. One dimension will be for note selection
– I’ll run some experiments and see if the breath controller filter is worth keeping
