How to use this workflow
Locate the passage
Listen to the source before soloing and note the low instruments you can identify.
Compare the evidence
Compare the bass estimate at an exposed note and at a dense passage. Separate a repeated synth line from a faint sustained background.
Save a usable reference
Decide whether the result supports your practice goal. If you need separate acoustic and electronic bass faders, request the original tracks.
Worked example and evidence boundary
Use this original decision worksheet: if a synth doubles the bass line, mark shared role; if a pad only overlaps the low register, mark possible leakage; if the mix has synth bass and no bass guitar, mark synth as the intended bass source. These are listening hypotheses, not measured classifications. Confirm each against your actual source.
What to verify before using the result
A frequency filter can reduce some overlapping material but cannot guarantee instrument isolation when both sources share frequencies. The current splitter has no acoustic-bass-versus-synth switch or MIDI extraction. Keep any uncertain instrument label out of a definitive transcription or client delivery note.
Common questions
Will lowering the bass stem remove only the synth?
No. Reducing the role changes all audio in that estimate. Independent balance requires separate source tracks or a different supported separation target.
