A single question of my own to start. Does anyone know the file format
of a saved MED (v 3.0 preferably) song? I'm thinking of doing a song
merging program (unless it's been done ? :-) Julian and myself are both
interested in this so please cc any answers.
Thanks,

Subject: Music-X Librarian Protocols
Hi,
I had a frustrating weekend trying to get Music-X to have a conversation with
my Korg Poly-800II synth. After messing about with protocols, I seem to have
the following problem. The Korg's system exclusive message "Dump data" sends
a 2688 (or so) byte copy of it's internal memeory to MIDI out. It's sent in
the nybblised format, so the protocol to read the data is:
PR,{{(Y.A80)}},(K&7F),F7.
Using LookOut, I checked what was happening. There were a mixture of "Protocol
errors" and "MIDI communication errors", and LookOut reported multiple read
errors and re-tries. I *could not* get Music-X to load the library from the
Korg. This, I presume, is because the AmigaDos filing systems tasks are
causing mis-reads from the serial port. In order to get any valid data across,
I had to unplug my Hard drive and my 2nd floppy, and even then it was
unreliable. Could this simply be due to the fact that I'm transferring a large
(2k) chunk of data? The Korg doesn't handshake, so I can't transfer the data
in blocks. Is there a clever way to do this? Has anyone had similar
experiences?
My system is A500+ 0.5M internal RAM + A590(0.5M ram) + external floppy.
My hard disk has 4 partitions. If I could reduce that, might this beast
work?
