I've only used Cakewalk Sonar as sysex administration
- it both have pauses in stream to allow receiver to tuck away and pauses between each sysex block
- some seriously large sysex like Hammond was helped by that
Other things, use DIN Midi interfaces, not usb. Midi interface is not the main product of REV2 or any synth, so less attention to that, I think.
But with REV2 used all banks at the same time, and a Mio interface could freeze and make entire interface needed unplug and replug. So it choked. So switched to Nektar one, and that was fine.
I assume you know about the debug screen where you can write all banks over to factory banks, if that might limit amount of transfers needed.
- keyboard version both transpose buttons and Global button gets a menu
- desktop version LPO1 and LFO4 plus global button do the same
Just a few ideas...
