Hi Ralph,
Mark passed away this past January (you can
see this other thread).
He and I were very good friends (I'd worked with him here at Notation Software for many years) and we often shared our personal music projects with each other. From what he had told me about the parallel interval pieces, he had some scribbled scores that he had not gotten into Notation Composer yet. He had done the audio recordings in anticipation of doing some testing with the Melodyne Editor's MIDI export feature to see if he could get a good .mid file from the audio recording. During that testing he had intended to get the scores into Notation Composer either via recording directly using a MIDI keyboard (he had a really nice Yamaha disklavier) or by note entry using the mouse so that he could directly compare the Melodyne export with the "real" thing. Sadly he did not get to finish that project, nor a few others he was working on.
ttfn,
Sherry
