29 MODEL D User Manual
6.4 Poly Chain System
Poly Chain
If you have multiple MODEL D units, you can connect them
in a Poly Chain as shown, so that the rst MODEL D plays the
lowest note, the second MODEL D plays the second lowest
note, and so on, to produce polyphonic sound.
1. Each MODEL D must have the same MIDI channel number
set using the rear panel switches.
2. Only set the Poly Chain ON for the rst MODEL D in
the chain. This is done by pressing its A-440 switch,
"on, o, on, o" within the rst few seconds of powering
on. The Power LEDs will ash fast four times when Poly
Chain is ON. The other MODEL D units will automatically
work in Poly Chain mode once the rst unit is set up like
this.
3. Adjust the controls of each MODEL D to be the same,
similar, or experiment as required.
4. If the Poly Chain system is no longer required, turn o
the Poly Chain mode of the rst MODEL D by repeating
step 2. The Power LEDs will ash slowly four times when
Poly Chain is OFF.
