TUNE MODE
The MKS-900 features the Tune mode in which
it can tune the connected sound modules. To
turn to the Tune mode, simply set the Chan-
nel Selector to the TUNE. The Display will
show flashing A-4 for about 3seconds, and
The Key Indicator A4 will light up. Then each
sound module will output A4 note for you to
use for tuning. Here, the MIDI Channel Requ-
est Is also transmitted, so that tuning can be
automatically done, if the sound module fea-
tures Autotune function.
if the Filter Switch is set to ON, Anote will be
continuously heard. This is useful for tuning
piano like sound.
When you have finished tuning, change the po-
sition of the Channel Selector Switch.
*For about 3seconds after the Channel Selec-
tor is set to the TUNE position, the connected
sound module is muted. So if you do not want
to be annoyed by the sound from the sound
module, simply rotate the Channel Selector
quickly enough.
*The Tune Request is transmitted right after
the MKS-900 is turned to the Tune mode or
the Filter Switch is changed to ON.

The MKS~900's are assigned to the sound mo-
dules which are to be driven by the computer.
Set the Channel Selector of each MKS-900 to
the appropriate Channel number that belongs to
the connected sound module. Now, the perfor-
mance of each sound module can be respective-
ly glasped on the MKS-900.
NOTE
*If you change the positions of the Channel
Selector with the Filter Switch set to ON, you
may be annoyed by the Pitch Bender or Mod-
ulation effect which goes on undisirabiy. To
avoid this, turn the Pitch Bender and Mod-
ulation effect off before moving the Channel
Selector. This applies to the On/Off of the
Filter Switch.
In this setup, asequencer is used, and several
MIDI channels are sent to the MKS-900. Set
the Filter Switch to OFF and the Channel Selector
Switch to the MIDI Channel number you like.
The part of each instrument can be visually gla-
sped without affecting the performance. When
the Filter Switch is set to ON, only the sound of
the selected Channel will be heard, therefore
you can easily tell which synthesizer Is played,
on which channel.
