I want to use the playMem function to play a wave I'll generate for given note to get texture of that note. The 11 notes will have a fixed mathematical relationship to the key note. I'll generate each note at the target frequency but I need to allow the player to adjust the pitch for the instrument up or down. I'll recalculate the new frequencies based on the input given. Can this be done with a function I haven't found yet. Thanks.
