JambaLaya MIDI Performance Software For Macintosh OS X

The Mixer Channel is the place to set up a complete audio and MIDI path. From the top down:

MIDI Input Selector: Choose which MIDI buss to read for control information.

Audio Source Selector: Click the triangle in the colored tag to pop up a menu allowing you to select an audio source. An audio source can be a virtual instrument, an audio input (or stereo pair) from your audio interface, or an external synthesizer defined in Audio MIDI Setup. All sources are treated equally in JambaLaya, allowing you to use it as both an instrument host and a conventional audio mixer.

JambaLaya lists MIDI devices defined in Audio MIDI Setup along with virtual instruments and audio inputs in the Mixer Channel source signal selector. When a device is selected, a viewer pops up allowing you to specify the audio input that the device is plugged into and selectors choose which bank and patch to use. This information is stored with the song so switching songs switches patches on your synth. JambaLaya is the only MIDI performance application to treat virtual and external synthesizers as peers.

Use the MIDI Learn window to map MIDI control messages to mixer faders, solo, and mute buttons. Just select the control to map, then move your external controller. The last received message is remembered as the control message. Map your entire mixer to a hardware controller in seconds.

Drag either end of the colored bars to specify keyboard range mappings. See which instruments are mapped where at a glance. No more trying to remember if that lead instrument starts at C5 or C6.

Access MIDI Channel Routing, Event Filtering, Note Doubling, and keyboard transposition from the easy to access MIDI Detail Panel. Use Transposition to move things into a more convenient key or move things whole octaves to more flexibly map your keyboard. Move that harmonica part down to the far left, then transpose it up so it doesn't sound like a foghorn. Clicking the colored track label changes the background color of the detail panel so you can see what channel has focus.
