transposition is a simple case of adding a constant to the pitch value in each midi note. That seems feasible to do realtime but you have to learn more on how the midi notes are accessed via the midistream obviously. I would look at how TMidiplayer is handing the data over to TTrackoutputs in the source code. Have you tried e-mailing the author of those components? DJS

Or is it something you do before you play the midi?
