Mac & PC musicians worldwide are creating songs together no matter how far apart they are. RiffWorks T4 users get 24 tracks/layers plus drums while collaborating. An unlimited number of musicians may contribute to a song (4 at a time). Contributions are saved on and can be opened later in RiffWorks to continue recording. As a track is recorded, it streams to other players and is perfectly in sync. RiffWorks loop-based recording workflow allows collaboration without latency or distance issues. For a small fee RiffWorks T4 users can collaborate online with musicians worldwide. Includes 4 tracks plus drums, 7 effects, InstantDrummer, AmpliTube 2 Duo LE and Studio Devil BVC amp plug-ins, a Quick Start tutorial in 14 languages (Danish, Dutch, English, Finnish, French, German, Greek, Italian, Japanese, Nowegian, Portuguese, Russian, Spanish, and Swedish), and more. Record ideas at the moment of inspiration, create songs, and cast tunes to. RiffWorks T4 is free guitar recording software.
