Render tool

live_render_track bounces a track’s pre-FX audio over a beat range to a WAV in the temp directory and returns the path. It is the seam the Gain Stage Doctor extension measures on. The render is pre-FX (the source level into the track, before the track’s own effects) and practical for audio tracks; it does not produce a post-FX master bounce. It produces a file, so there is nothing to undo.

live_render_track write

Render a track's pre-FX audio over a beat range (startBeat..endBeat) to a WAV file in the temp directory, and return the path. The render is PRE-FX (before the track's device chain) and practical for audio tracks; it is not a post-FX master bounce. This writes a file and does not change the Set, so there is nothing to undo.
