Arduino MIDI pad

I’m working on a MIDI pad made from a Teensy Arduino and a bunch of components that I found online. Imagine something like an MPC but not as cool. I’m totally not a musician but it’s really fun to make!

I’m calling it a MIDI pad but it doesn’t depend on MIDI at all. MIDI is an interface standard between a musical hardware and a computer so I use this standard to communicate impulses to a computer or mobile device via USB. For example when you press a pad it will send some data to the host device saying a pad has been pressed and the host device will create some kind of sound. This could be a sine-wave tone or a sound file.

It’s using force-sensitive resistors to track the velocity of how hard you hit the pad.

I want to be able to change different noise parameters like note pitch, attack/decay, reverb etc so it also has six extra buttons that can be used to toggle modes on and off. It also space where my phone can sit and be plugged in to produce a touch interface with sliders and stuff.
