The ReBirth Input Machine is a device dedicated to receiving audio from the Propellerhead program "ReBirth RB-338" (version 2.01 and later). This is achieved by using ReWire technology, where Reason will act as master and ReBirth as a slave device. If you don't have ReBirth installed, you cannot use this device. If you are a ReBirth user, you can use the ReBirth Input Machine for the following:
Receive up to eighteen channels of streaming ReBirth channels in Reason.
You can create more ReBirth Input Machines, but only one can be active at a time.
Sample accurate synchronization between the audio in the two programs.
The two programs can share the same audio card and take advantage of multiple outputs on that card.
