Introducing ReWire! To make this integration between two audio programs possible, Propellerhead Software has developed ReWire. This technology provides the following possibilities and features: In ReWire version 1 • Real time streaming of separate audio channels, at full bandwidth, into another audio program. • Automatic, sample accurate, synchronization between the audio in the two programs. • The possibility to have the two programs share one audio card. • Linked transport controls that allows you to play, rewind etc., from either program. • Less total system requirements than when using the programs together in the conventional way. In ReWire 2 A number of features were added in ReWire version 2. The following are the most important: • Up to 256 audio channels (previously 64). • Bi-directional MIDI communication of up to 4080 MIDI channels (255 devices with 16 channels each) • Automatic querying and linking features that (among other things) allow a host to display the Device’s instruments, controllers, drum sounds etc. by name.
