Native multitrack stem export from source tracks (not post-mix separation)

The problem Stems extracted from a finished mix have a hard quality ceiling. For producers, the gap between Songer's current stem output and what external splitter tools can already do isn't wide enough to justify the workflow. Since stem quality determines whether the output is actually usable in a real production, the current approach falls short for that audience. The ask Make the individual generated tracks (vocals, lead instruments, rhythm, etc.) available as clean, isolated stems straight from the generation step, instead of (or alongside) the existing extraction-from-mix flow. The goal: true multitrack stems, not separation. Why it matters For the producer segment, stems are the headline reason to subscribe to Max. Native multitrack export would close the gap with professional DAW workflows and make Max an unambiguous value for anyone bringing Songer tracks into a real production, remix, sync placement, or sample pack.
