Why are you guys telling him to use OctaMED SS 1.03c on an Amiga 600 (68000cpu)?
I've always been told it's a hog on a machine of this low spec, and one would be better off getting OctaMED 4.0 for a 68000 machine.
They are virtually similar in functionality when working with 4 tracks. SoundStudio gives you superior mixing, panning and 16-bit sample use, but if he's got an A600 then 16-bit is out of the question anyway.
By the way, OctaMED 4 is also public domain - having been released by the other and distributed on some Amiga magazine cover disks.

Something he may want to consider, though I also started using OctaMED S.S. on a stock A500 with 4 or 6Mb of RAM total and was still able to run the program well, though of course some of the more advanced features that OctaMED 4 don't have anyhow, were not available.
When I later upgraded to more powerful machine, I was then able to more fully explore the software.
