"qMI Three Channel Composition" [3.5 MB .mp3]
Recently added module -- Vermona's Quad MIDI Interface -- allows you to write polyphonic tunes with monosynths and/or mix four-part harmony in the synth's mixer without later overtracking. These are both done that way. Starting out nursery-rhyme simple; hope to be doing Bach by the end of the year.
