Hi,
Maybe this is a little late for your user, but just to add to the
record...
So, besides the one (with GUI) for the Mac, is there anything else
recommended ? The advice for Csound et alia is good, but the asker
doesn't know any audio programming languages.
Pure Data: http://puredata.info/
It is an audio programming language but it's visual,
so might id well suited for that and it can go from simple oscillators
to funky maths. I would take a look at it.
