Hey @dltfm - thanks for this amazing tool!
Check out my post below. Would you consider adding the functionality I describe here, so that The Deliverer can extract effected stems exactly as they appear in the context of a song, which, when summed, would sound precisely the same as the master output? Essentially I realised, after trying to extract a set of “wet” stems, that muting unwanted tracks - rather than soloing as you go - produces stems that incorporate effects that are dependent on other tracks, eg a signal follower controlling the “ducking” of a stem you are extracting.
