Cool thread!
The only recording I do with it is for live remixing of my Model Samples, and Typhon. And for transitions.
I don’t record into it to bring in audio to work on tunes, in the traditional sense. I just use a DAW for that. The audio I use to write tracks on it all come in on the CF card.
The MIDI sequencer is rarely used since I got the MS. Previously I used it to sequence Ableton Drum Racks. see: Octatrack MIDI + Ableton Drum Racks = Powerful Drum Machine!
I never use the arranger, just like all other hardware I’ve ever owned that had a song mode.
While I do use a Twister controller for some audio tracks, I don’t use the CC direct connect, since the parameters the Twister controls are not ones I want to interact with on the OT and I only use the Twister on the same Bank and Part (controlling FX for external input tracks). It’s something I could set up, but then I’d have to complicate my setup with a thru box and additional MIDI cables, and changing control setups on my other gear. It’s just easier for me to ignore the CC direct connect feature.
Cue outs aren’t used either, as my inputs are all taken up by MS and Typhon, and I don’t want to add a mixer to bring back an FX return. So the Blackhole pedal I use is a master reverb run out of the main outs at about 20% wet with the low reverberations killed.
Finally, I try not to use multiple projects. Preferring to make the most of a single project so that I have the most material available for live performance without project reload. Occasionally I’ll copy the project and remove the stuff I won’t use live from the new copy, to make room for new material. And then the old stuff just lives on the backups. Constantly iterating.
