This is going be a bit rambly because I'm just starting to think seriously about how I'm going to do this and am already coming up with various obstacles and mental knots to untangle.

The goal of my next challenge is to record in real time a performance using just the Lyra-8 and Subharmonicon. And maybe a kick drum or some other minimal percussion? Not sure.
I have my effects chain already done (discussed in another thread) and a BOSS RC-5 looper. My goal is to have the output of the looper going straight into my interface and press record. What it gets is what it gets, so I'm expecting this to take days or weeks to get a performance I can live with. As I am off the last two weeks of November, that's my target to work on it in earnest.
The first challenge I was met with was: how long will this be? And will I have any control over how long it will take to get it 'right', or at least 'good'? My guess is that this piece will end up being quite long, probably between 20-30 minutes total. That doesn't worry me, my pieces tend to be very long anyway.
But how to approach this with the looper had me stumped for a few hours today. My original idea was to record 30 minutes of blank space and then overdub layers. However that would lead to the piece being hours long! I kept trimming and trimming and I think I've settled on a length of 1 minute for the track. If I start with a 1-minute long blank, I can then get the first drone layer up, overdub, and then 'perform' each subsequent layer as I improvise, record, and layer again and again.
The idea is, in theory, when I have a dense enough bed of layers, I can improvise a 'lead' layer of the Subharmonicon over the rest. I'm pretty happy with this approach and it looks pretty sound. I'm sure that during the coming weeks this will be modified and tweaked to match the real world constraints of doing this all live -- to say nothing of becoming proficient in improvising with this setup in the first instance!
Overall, I'm excited to start documenting the project here and am looking forward to recording something as a 100% live performance.
