24 QuadraSynth Reference Manual
Typical Application 1: MIDI
Keyboard/Master Controller for Live Use
Most live applications use the QuadraSynth to generate sounds, with (possibly) the
MIDI output driving other MIDI devices, such as a QuadraSynth S4 rack unit,
QuadraVerb Plus, and other keyboards and sound modules, etc.

To drive MIDI controlled devices from the QuadraSynth, patch the QuadraSynthÕs
MIDI OUT to the MIDI deviceÕs MIDI IN. If there is more than one MIDI device,
patch the first deviceÕs MIDI THRU to the second deviceÕs MIDI IN, the second
deviceÕs MIDI THRU to the third deviceÕs MIDI IN, etc.
In Program mode, the keyboard sends and receives MIDI information on only one
MIDI channel at a time. In Mix mode, however, the keyboard can transmit on as
many as 16 MIDI channels, each with its own keyboard range (for more information
on Program mode and Mix mode, see Chapter 4).
When using the QuadraSynth as a master keyboard to play other MIDI devices, be
sure the Keyboard Mode is set to ÒFRM MIX.Ó The Keyboard Mode parameter is
found on Page 2 of Global mode (for more information, see Chapter 8).
Caution: Do not attempt to connect more than three or four units together using thru
connections as this may impede the MIDI data flow to the connected devices.
Instead, insert a MIDI patch-bay to the QuadraSynthÕs MIDI OUT so that all devices
receive its MIDI information simultaneously.
Using the S4 in Live Performance
Depending on the capabilities of your MIDI controller keyboard, you have two
different options available for how the S4 will respond when it is in Mix mode:
If your controller can only issue commands on one or two MIDI channels
simultaneously, you may want to set the S4Õs ÒMix Group ChannelÓ parameter (on
page 2 of the Global display) to a channel between 1 and 16, so that your controller
can play a mix of several S4 programs in response to a single channel of MIDI.
