Just dropping a thought:

I'm mixing a huge project file with many heavy VSTs, each of which with unique settings (so applying FX to the bus is out). My computer is a shitty old laptop.

I'm happy with my drum mix, so I'm going to solo the drum bus, render it, and then re-import that as a single two-channel stem. Fewer tracks for Reaper to handle, hopefully less CPU.

-s

Edit: It worked! and it worked even better when I made it a drum + bass stem!

Edit 2: My God, Reaper has a function that does this for you automatically. It's called Freeze Track. They have thought of everything.

Here it is in the manual: https://dlz.reaper.fm/userguide/ReaperUserGuide731d.pdf#page=117 (section 6.17)

You can do the same thing by freezing tracks. It will reduce memory and CPU usage for VSTs and tracks. You also have the option to freeze partial tracks, or only selected plugins that are CPU intensive.

Also, you don't have to render and re-import the track. There is a function to render to a stereo track that holds everything internally. They are under the TRACK functions. Select the tracks you want to lock and freeze them. You can unfreeze later to make changes if you need to. The result should be the same... .a stem track that uses no VSTs or FX, just a straight audio track.

@TalismanRich this has made my life so much easier :) you don't know the juggling I was doing to keep my PC running... "I gotta wait till this part is over to open the compressor interface or Reaper will crash" lol
