To be more exact: I want to have every C1 in my MIDI regions played back as the note C0 by my software instruments. There used to be some kind of drum map in earlier versions of Logic, in the left area's playback parameters box. Any ideas for how to set up this in LPX? (except for cabling through a Transformer in the environment). Many sequencers have note transposers where you can define an IF statement to only have one note transposed; I'm doing it a lot in Bidule for example and have an excellent VST MIDI plug-ins suit that I can't recall the name of at the moment, so I guess it shouldn't be very complicated.
