On modern hardware

How can one add sounds to plugin files using modern hardware? I'm on an Intel MacBook running Snow Leopard, which cannot run ResEdit. I do have access to an old iBook G4, though. Would I need to use that to add sounds to a plug? Or is there an option that I can use on newer machines?

If you know how to add sounds using ResEdit, then I suggest Rezilla. It's basically the same application but for OS X. A bit down from the top of this post you'll find a link for Rezilla and a plug-in to turn it into an editor of sorts for EVN.

Okay, thanks. I think that might be what I'm looking for, but I'll need to try it to be certain.

rezilla is a great replacement for resedit
