Salutations David for on the 11 Mar 96, verilly did you scribe;

Assuming you don't use some nifty more efficient method to store your
samples of course...

Ah ha. Sounds interesting. Personally I think we need a CyberSFX RTA system
and a relatively cheap multi channel sound card for the Amiga. Just this
with Octamed Sound Studio support would make the Amiga a killer audio
platform again.
