Hi,

I've been meaning to reply to your email for a while, but I was waiting
until I had time to test my own SysEx code with NetBSD 3.0. A while ago
I wrote a patch editor and librarian for the Roland Alpha/Juno
synthesiser[1], but I encountered problems with SysEx dumps. Like you, I
found that the dumps would stop after the first couple of bytes. I sold
my Alpha/Juno last year, but I've just bought a Roland W-30 workstation
and I'd like to write a SysEx dump librarian for it. My MIDI interface
is a Yamaha UX-96, but the problem seems to be in the generic MIDI code
rather than the USB code. The original author (Lennart Augustsson I
think) said that the SysEx support was untested. I'd be happy to
coordinate debugging efforts with you if you're still interested in
fixing this problem.

Regards,

Chris
