I want to be able to have an arduino control a tablet (Iconia One 10 (B3-A40FHD)0 ) to play MIDI and audio files simultaneously.
The Midi files are being used to control Teensy USB Development Boards to control stepper 12 motors.
Each teensy will respond to a different channel.
The audio will be be output through the headphone jack and will run simultaneously with the Midi file.
I am using the Iconia One 10 since it has 2 USB ports. I will use one to output the MIDI file and the other to communicate with the Arduino.
I need some way for the Arduino to tell the tablet to play the files. There will be different files for different routines that will be selected by buttons that will trigger the arduino.
I have no idea how to do this but it seems as though it should be able to work
Any and all help will be appreciated
