Quick update: I noticed that J:\bb is creating the file ...

06/04/2024 08:42 PM 10,666,030 DRUMS_TEMP_RENDER.WAV
(filesize is an intermediate size before it's done writing to the temp file)

While C:\bb\DragDrop is now creating the [origfilename]_render.wav temp file.

What I had to do is:

1) Restart BIAB
2) Move the MGU file to the C: drive (it was previously saved in J:)

Now my renders using drag/drop are taking under 3 minutes (around 3.5 minutes if regeneration is necessary) even though the J:\bb\DRUM_TEMP_RENDER.WAV file (which ends up being ~60MB) is being created. This is a big improvement. I'm not sure I understand why the DRUMS_TEMP ... file is stubborn and stays in j: but I'll take a 4x improvement any day. If I could force DRUM_TEMP to C: somehow, I'd probably shave off some more time.

Thanks for the tip -- it got the ball rolling.

I retested the original "normal" audio render (not drag/drop) and with the MGU file on C: this also takes ~3min. So it looks like the big savings here is moving the MGU to the "fast" drive. With the "normal" audio render the same DRUM_TEMP file is showing up in J:\bb as drag/drop.
