I am also thinking about this.
But honestly, i dont want to loose stereo.
Carefully selecting and ordering your sounds/samples that goes to you devises and know them in and out is key.
Then, add samples and sounds to your soundpool that might fit into the song/project.
When you are in live performing mode, tests samples/sounds when you are unsure if they fit with a single manual beat-matching trig.
I route my elektron devices to Ableton and use the cue output. I recommend using a looper device as well so you can pre-listen new tracks while the loop is still playing.
And I fully agree with the previous tips:
Categorize your tracks per BPM and scale so you know which tracks will fit
Don’t go crazy with the stereo field if you’re planning to play in clubs. I almost never pan my tracks.
Your proposal seems a bit cumbersome to be honest. You want an approach that’s super intuitive and easy to use. You’re never on your A-game when playing live (nervous, a bit drunk, etc) so keeping things extra simple is what works best for me.
