The point I was trying to make was;
PGMusic products require you to set a bit rate for a project.
If you want to end up recording 24 bit somewhere along the line, you should set it at the beginning.
RB will convert the WMA or wavs to 24 bit as you generate .. and when you record your own audio tracks they will record at 24 bit.
Since this appeared to be the desired outcome, my suggestion was to set the project to 24 bit early on and not have to worry about up-converting your recorded tracks later. Matters not if the generated tracks were WMA originally .. your end result (recorded tracks) is the bit rate (I think) that was desired and suggested by others.

Much better to do this than try to up-convert finished product later (as Herb pointed out). That's route is pretty fruitless really.

And yes most use 32 bit floating rate *for the math* (during processing), not the bit rate conversion once written.
Eventually things get defined.

I do not work here, but the benefits are still awesome
