I read mention that sysexxer (?) is no longer
maintained,
It still should work. I heard rumors that there will be a replacement.
so which app
should I use? In my Windows days, a MIDI sequencer could do this, so
I'm guessing that I might could use Rosegarden, but I haven't
confirmed this. Any suggestions?
At least MusE should be able to record and playback sysex, and I doubt
that Rosegarden doesn't.
And at least there's amidi on the command line.
Best regards
