Unmixing Stems

I just updated to SpectrLayers Pro 7.

What does the sensitivity parameter control/modify technically when you are unmixing stems? Without an explanation it is hard to tell how to operate it optimally.

Start by unmixing without changing anything in term of sensitivity (0). Then solo each individual layer to listen to them separately and identify if some instrument is bleeding too much into a layer where it’s not supposed to be. If so, undo the unmixing, and reduce the sensitivity of that instrument that bleeded too much.
Likewise, if it looks like a layer did not fully capture an instrument it was supposed to, you can increase the sensitivity of that instrument. And then unmix again.

Thanks! I can get much better results now.
