2) Logic: Import MIDI, invert, render to audio

Does Logic have a better synth to use for the render to audio portion?
Do you have hardware synths available?
The Invert part could be fun, but the generated sounds could be better IMHO
Once you import MIDI and Invert it, can you save it off to use in another program as a basic MIDI file (.mid)?

Make your sound your own!
.. I do not work here, but the benefits are still awesome
