GameMaker Piano

This example shows how to create Piano in GameMaker, using audio "pitch" param only. Source code: https://github.com/gmclan-org/piano_example (This example wouldn't be created if Juju Adams wouldn't tell me magical yet simple formula that does the job: pitchShift = power(2, semitones/12) - check Juju's github for lot of useful GM libaries - https://github.com/jujuadams)
