QuadraSynth Reference Manual 27
¥ Or, the keyboard only sends on one MIDI channel, but you change the channel
on the QuadraSynth for each separate track on the sequencer (CH SOLO).
In OUT 1 Ñ OUT 16 mode, you will not hear the QuadraSynth unless your
sequencer echoes the MIDI data back to the QuadraSynthÕs MIDI IN. This is a way of
verifying that the sequencer is set to receive properly. Depending on the capabilities
of your sequencer, it may Òauto-channelizeÓ the echoed MIDI back to the
QuadraSynth on a different MIDI channel (usually, the MIDI channel that the
selected record track is assigned to). In FRM MIX or CH SOLO mode, the
QuadraSynth sounds are internally played from the QuadraSynth keyboard, so any
echo features of the sequencer should be turned off.
When using the QuadraSynth with a MIDI sequencer, the usual choice for the
Keyboard Mode is ÒOUT 1.Ó This is equivalent to turning the QuadraSynthÕs local
control off. For more information, see page 45
Using the S4 with a Sequencer
For most sequencer applications, the S4Õs ÒMix Group ChannelÓ parameter (on page
2 of the Global display) should be set to OFF. See page 109 for more information.
Pedal and Footswitch Hookup
The QuadraSynth keyboard has two PEDAL jacks that accept a Roland model EV-5
(or equivalent) volume control pedal, or a standard switch pedal. Each pedal can be
assigned to independent modulation functions within a program. Example: One pedal
could control volume, and the other vibrato depth.
The SUSTAIN footswitch jack accepts a momentary footswitch unit, included with
the unit (it is packed in the center of the end caps). This provides the same function
as the sustain (or damper) pedal on a standard keyboard. You can use either a
normally closed or normally open momentary contact footswitch. Plug it into the
rear panel SUSTAIN footswitch jack before powering up the QuadraSynth; on power
up, it will automatically sense the footswitch polarity and calibrate itself accordingly.
If your footswitch seems to respond backwards (notes sustain unless the footswitch is
pressed), turn off the QuadraSynth, make sure the footswitch plug is fully inserted into the
footswitch jack, then turn the power back on.
