(9) Set the basic channel of the connected MIDI keyboard to channel 1. In this
configuration, either keyboard can be master or slave. The keyboard on which
you play becomes the master. In this setting, the sounds of both keyboards
- can be played in ensemble to make a "thick voice or totally new sound.
* The polyphony of the CT-670 unit is 12-note in the MODE A.
* Use as multi-timbral sound source
By connecting the CT-670 to a multi-track sequencer and setting the CT-670
to multi-timbral mode (MODE B), a single CT-670 unit becomes capable of
handling the rhythm, melody, bass and obbligato parts at the same time.
* In the MODE B, the polyphony of each channel is;
channel 1=6-note, channel 2=4-note, channel 3=2-note and channel 4=4-note (when used as
the fourth voice).
