Step - output for performance

Hi - So the input thread establishes that the stereo input ends up in the output of the polyend step, unaffected. I have a few questions about the output:

  1. Not possible to change the relative levels I assume. Stereo input level informed only by what is feeding into the Step, and the Step volume would control the combination of input and output. Right?
  2. If I want to minimize cables, if I just do one of the outputs (say, left) will it represent the whole sound of the input plus the Step output, at least for the default songs and tracks? Or is there any panning setup with the default tracks and kits, so a single mono output would not represent the sound well?

Those are some specific questions. In general I’m also looking for a recommendation on how to best run the combination of pedalboard plus step into a speaker or amp with the least complexity (eg number of cables) and the best sound.

Thanks!
