JambaLaya is an AU host designed for live performance. Size the rainbow colored bars to set up keyboard splits and layers. Eight mixer channels can take either audio input or virtual instrument as the sound source and provide four insert effects. This allows guitar and bass players to jack in and take advantage of great amp emulations.
JambaLaya also supports external hardware synthesizers by sending MIDI patch change information when switching songs, putting your virtual instruments and legacy hardware on an equal footing in your rig.
Songs can be arranged into sets by dragging. MIDI learn is extensively supported for switching songs and mixer controls. JambaLaya also replaces your 'fake book' by storing a chunk of styled text with each song and displaying them in the lyrics view.
JambaLaya is for players. There is no support for recording or sequencing.
