As far as i know… the octatrack just doesnt do sysex sequencing in any way or form…
so yes. if you want to save/store/restore SysEx files you need a librarian-like tool.
C6 will do it… midiOX will do it… but your octatrack will not.
the octatrack sequencer can only handle CC events as far as i know.
you cannot record/play nrpn’s or sysex with your octatrack… u might be able to trick your other gear if you combine the correct 2 CCs in the correct order into creating an nprn message… but thats not something i would recommend doing / persuiing.
to make things even more complicated… the octatrack sequencer will only record CC information if you teach one of the knobs to “react” to that particular CC…
for your information… the only 2 hardware sequencers i had that could correctly record/playback both nprn and sysex information was my roland mc909… and my roland mv8800…
and please dont take this as a shitty cliche thing… but do yourself a favor and actually google:
What is midi
What is a continious controller (midi)
what is System Exclusive (midi)
knowing this information and understanding it… will absolutely help you out in trouble-shooting and or connecting various devices to eachother and making it work.
Enjoy
