I don't remember well. The playback of ticks was correct under OMS, as I remember demonstrating it in Cambridge under MacOS 9, and possibly it got broken in the MacOS 10 migration. Fixing it would only be interesting for BP2.9.9 which hopefully will be replaced with the new (BP2.10 or BP3 ?) So, I am not sure it is worth investigating, except for the pleasure of a challenge. ;-) In the same way, we might need "type from MIDI" in the interface rather than in the console. I still need to find how to do it. Perhaps simply using another piece of software picking up data from a MIDI keyboard and saving it as a MIDI file… I'll try to figure it out in the Timebase editor.
