Rear panel

Any MIDI device (sequencer, keyboard, WX7/11 wind controller, G10 guitar
controller, etc.) can be connected to MIDI IN to play the sounds of the SY99.
Data produced by the SY99 keyboard and the SY99 internal sequencer is
transmitted from MIDI OUT. By connecting a tone generator module or synthe-
sizer to this terminal, you can play it from the SY99 keyboard.
The data received at MIDI IN is re-transmitted unchanged from MIDI
THRU. Another MIDI device connected to this terminal will receive the same
MIDI data that the SY99 receives.
This knob adjusts the contrast of the LCD. Adjust it to suit your viewing angle.
(At extreme settings the display will not be readable.)
By connecting an optional BC1 or BC2 breath controller to this jack, you can
expressively control various aspects of a sound by blowing into the breath con-
troller. For example, a voice might be programmed so that the tone or volume
changes in response to breath controller signals. (The effect will depend on the
breath control sensitivity parameter settings of each voice.)
This knob adjusts the volume of the click (metronome) produced by the
sequencer.
An optional foot controller (FC7, FC9, etc.) can be connected here to regulate
the overall volume of the SY99.
An optional foot controller (FC7, FC9, etc.) can be connected here to use in
realtime modulation of voice parameters assigned to the foot controller in Voice
Edit mode.
