I'm in the planning stage for a university project, and want to know if this is even possible to achieve.
Basically my idea would be to have a guitar signal directly to an Arduino unit like in this Tutorial here: https://www.arduino.cc/en/Tutorial/AnalogToMidi. Only to take it to another step where an Iphone/smartphone would be able to receive the midi inputs and play the corresponding sound from IOS Garageband or something similar via Blutooth from the Arduino. If anyone has any info or existing resources this would be great! I've never used Arduino physically; any logistic information or opinions on if this is even possible would be appreciated.
