I think the Octatrack is a lot like a modular synth but it’s like the recorder/sampler/looper equivalent of a modular. And I think just like with modulars there are essentially two modes of working.
The first is sort of an experimental approach where you sit down with a blank slate and explore whatever thing you don’t quite understand or haven’t tried yet, or you have a certain idea you want to explore. With a modular it’s like starting with nothing plugged in and thinking “what happens if a plug x into y”. With the OT it would be starting with an empty project and exploring some idea you haven’t tried yet like “what if I make a scene that does x”.
The second mode of working is when you have a specific goal in mind and you set it up to accomplish that task. If you have an idea of what you want to use it for you can just go straight to that and figure it out by asking here or searching. But the two modes work together. You play around and experiment, discover new things, and then you have more tools in your toolbox for when you want to be in mode 2.
This might be controversial but in a way I don’t think that the OT is really an instrument that you master. It’s more like a toolbox or a system that you play instruments into, kind of like a daw.
It’s also really not that hard, it just has some quirks that seem weird when you don’t understand why they work that way. I think the “history” suggestion makes some sense. Like it seems to me that pickup tracks were added later as sort of a template to be an easier to use premade looper rather than just learning to set up a flex track as a looper.
Just play and experiment, have fun, take baby steps, and don’t jump into doing anything too serious. I think people start out trying to make full tracks and then rage when they lose what they did. I’ve been trying to learn it by just doing casual experimental stuff and recording the output to another recorder so it’s no big deal if everything gets screwed up.
For example, I didn’t try the MIDI section at all for a while, so lately I’ve been taking one synth and the OT, and sequencing the synth via MIDI with lots of probability and making some kind of weird aleatoric thing, then recording it into a loop, adding effects, lfos, plocks, etc then changing the sound on the synth and adding another layer, and so on to build up some krell patch type of soundscapes. I’m using track 1 as my recorder and have all of the memory allocated to recorder 1 and then have all of the other tracks set as flex tracks so I can easily keep looping and building up multiple tracks.
But anyway that’s just an example of a “mode 2” type of system that I built up from lots of “mode 1” playing around and experimentation and thinking about what I wanted to accomplish.
