OK, stay with me on this. AND I think I've done this successfully before today, so I'm asking to make sure I haven't forgotten something.
1/- 2 instance of Vegas open: VA & VB
2/- Locate a piece of audio in VA, BUT want it in VB - just the Audio, not the video
3/- I don't want the whole piece of Audio
4/- Open Event within VA in the Trimmer
5/- Scrub to the bit of audio, create a highlighted Loop and Copy this to VB
6/- The Audio is a bit weak so I apply Audio Volume FX
7/- I get Low Mem warning.
8/- Can't open AS Copy in Sound Forge either - low mem
9/- Check all mem and gallons of it.
10/ Repeat experiment BUT doing this from within VA - this works
Soooo... I can copy from one instance to another, but it would appear I can't copy to another instance and THEN apply an FX ( here audio ) without getting a low mem warning.
PLUS, the Loop in Trimmer CAN be opened in SF - no low mem warning.
TIA,
Grazie
