[ Ref. 240413 MMD, How to Build a Laser Piano Roll Cutter ]

I know that I'm not the only one who was excited when Spencer Chase
started work on his laser piano roll perforator design! Now, after
seeing a video of the machine working (at a chipper pace, I might add!),
the only thing left to do was get a process together that allows for
_any_ Standard MIDI File to be converted to punchable G-code.

I have finally solved this last issue and now it is officially possible
to master hand-played MIDI files to a master file of 36 punches per row
that negates just about every chance of hearing the minute timing errors
introduced when rounding notes to the nearest punch row.

If you are planning on building a perforator using Spencer's design,
then I can do the dirty work to master just about any piano MIDI
file into a cuttable G-code file that you can then cut a roll from!
Hopefully, if things go well, I could make a video on the conversion
process as well, to make it easier for others to do the same.

Spencer has posted the documentation for his design and the materials
needed to build it. I encourage any tech savvy individual to take on
the project, as being able to finally put new music into rolls may just
slow the decline of mechanical music instruments powered by nothing but
air and the shear resolve of the people keeping them working!
