Application 3 - Using The MPL 1204 As A Keyboard Submixer
Here, various keyboards and MIDI tone generators are connected to the channel line inputs of the MPL 1204. Signal processors are connected to Aux sends and returns and to channel inserts as required. The Main output can then be routed to a stereo input channel of a live performance or recording mixing console, with the performer having complete control over the blend of signals being provided to the sound engineer.
