I’ve been genuinely surprised by how many people are still using paper rolls to control their organs, and how many organs are still being produced for this technology. The means used to bridge the gap between electronic composition and paper device control are interesting–they remind me of what I think happened in (Italian?) textiles in the transition to full mechanisation. Midiboek “converts standard Midi files to templates for street organs, pianola’s, music boxes and so on” and MIDster PUNCH is “way to punch your own music rolls in any format directly from MIDI files.” I want direct MIDI control from hard disk, so I can’t say that I’d use any of them. But it’s all interesting stuff.
