rebirth

One of my favorite music programs, from Propellerheads (the makers of Reason), is Rebirth. It is the most accurate software synthesis of Roland's TB 303, TR 808, and TR 909. Accept no imitation! There are probably hundreds of programs that claim to reproduce the classic techno sound of the 303, and I can affirm that Rebirth is the closest thing to actually owning a unit itself. The TB 303 is a popular bassline synthesizer commonly used in Acid or house music from around twenty years ago.  Both the TR 808 and the 909 drum machines have been used in pretty much every electronic or hip hop album since Adam and Eve partook of the forbidden fruit in the Garden of Eden. It is freeware (for the last few years) and can be downloaded from the Rebirth Museum.
