Re: MIDI sysex over Firewire - not supported by Jack MIDI?

Right, here's an old MIDI file that I think contains the sysex messages -

And here's a copy of the ER-1's MIDI chart -

I just timed the full data dump, and it takes 1:36 to complete. This is every knob and sequence setting over 4x64 patterns, and 20 songs.

cheers, Oliver

That is a seriously big chunk of data! Using Simple Sysexer My Yamaha QS300
takes about 30 seconds for a full dump.

It's a long time since I did any work with programs to send and receive SYSEX
(Acorn Archimedes) but I seem to remember that the sender could elect to send
just one massive block of data or a bunch of smaller ones. Do you know which
the Korg uses (is it switchable?)

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
