You can get
Rebirth for free as a torrent, pro software. It's an 808/909 simulator, really old school (built for Windows 98 I believe) and sort of archaic, but if you absolutely have to be legit and like that 808 feel, go for it.
Otherwise, grab Reason wherever. Redrum is highly intuitive and versatile (Dr. Rex loops help fill things out too) I do believe I owe you a copy, miss Squawk.
