Music Roll Editing Programs
By Karl Petersen
Great subject, and Robbie's right on the mark regarding project size.
The metronome structuring was made semi-automatic by the Hickman team at Ampico. The beginning of each beat was marked and the stretch and compression necessary to make even beats were mechanically created by changing the speed ratio between the recording and the next-master. This was supposedly only done on dance arrangements, i.e. fox trots, but would still be a good tool currently unavailable.
The editor Robbie is using shows the piano roll in sheet-music orientation, that is, it is a view of the bottom side of the roll with the tab on the left. This might be fine for those doing sheet music, while the vertical spool-box orientation might be better for the casual roll-handler who is not sheet-music wise. (hopefully not unmusical!) An option to view in either mode could be valuable.
Especially note the tracker hole offset and percussion strike-when-the-note-hole-closes questions. These are very music-roll specific.
OK, Jody, what are you going to title the spin-off thread on CO2 laser roll cutting?
