Had not thought about that?
not sure if the remark is ironic, but there are literally TONS of free soft synths around, at least for windows.
check google and type "soft synth free" or "moog emulator" or something and you'll find lots.
youtube can also be a useful way to "see" and hear wht it sound like.
once (and if) you get hooked, there should be people here to help with the technical stuff, since i don't own a mac.
