Right, here's an old MIDI file that I think contains the sysex messages - https://mega.co.nz/#!nJwglSSR!Ox0O47SqHQOnvm2-Z2AU2GKjn2aTBAvivQmyrEETpD0 And here's a copy of the ER-1's MIDI chart - https://mega.co.nz/#!nVQnxYrI!0gxzcXXQbO02k9OXlhkwNNXXORyAQZrJ3cg-RI5w0q8 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 Date: Tue, 9 Dec 2014 20:31:29 +0000 From: Will Godfrey <willgodfrey(a)musically.me.uk> To: linux-audio-user(a)lists.linuxaudio.org Subject: Re: [LAU] MIDI sysex over Firewire - not supported by Jack MIDI?

Can I use one of the drivers other than firewire? > 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.
