Note: If the Transmit Channel of the Drum Machine is fixed
on a specific Channel number and disable to be changed,
first (A) send MIDI Program Change number 100 (which is
corresponding to Voice number 76 PERCUSSIONS) from
the Drum Machine (or other Master device), or (B) assign
the Voice number 76 PERCUSSIONS for the same
Channel on the PSS-590 following the methods in
"Assigning Voice Selection on Each Receive Channel" on
page 33. Then set the Transmit Note number on the Drum
Machine as already mentioned. Even if this is not available,
when hitting the pads or buttons on the Drum Machine,
Desired sounds are not always reproduced from the PSS-
590.
« Example 4 » When making a Larger Polyphonic
ensemble
When you Receive a larger composition data (in case it is
required to sound more than 28 notes at a time), you can
use a MIDI connection as shown below. For example, you
can use two units of PSS-590, and assign the 1st PSS-590
(Receive Channels 1-8/Enable, the rest/Disable) and
assign the 2nd PSS-590 (Receive Channnels 9-16/Enable,
the rest/Disable). If you use two PSS-590s dividing their
Receive Channels like this, you can have them play in 56
Polyphonic Sounds capability.
