Yamaha PortaSound PSS-795 Owner's Manual page 42

That is, it enables you to start Auto Accompaniment running
at an identical tempo that is set on the Master, and stop it.
Note: Orchestration assignment, Fingering selection, and
Fill-in insertion should be operated manually on the
PortaSound. In matching the Transmit Channel on both
units, if you set Channel 10 to 16 (dedicated to Auto
Accompaniment), your performance and Auto
Accompaniment will run against each other. For example,
when you select a Voice or Style, the accompaniment
reselect another. So don't select Channel 10-16 as
Transmit Channel.
<< Controlling Song Memory by
External Keyboard >>
Step 1: First match the Transmit Channel on the external
keyboard with the KEYBOARD TRANSMIT CHannel on the
PortaSound.
That is all for you to control the Song Memory from an
external keyboard. And you can do the recording on the
Tracks: MELODY 1 to 5, PAD, and AUTO ACCOMP. For
recording onto VECTOR SYNTH Track, you should play the
Vector Synthesizer on the PortaSound.
Step 2: For actual recording, you can follow the same steps
as explained in "Song Memory Section".
Note: You can control Voice selection, Voice Effects from
the external keyboard. That is, Voice selection will be
executed by Program Change message, and Voice Effects'
value will be assigned by Control Change message. They
could be done by simply transmitting those message to the
PortaSound referring to the Correspondence Charts (: on
page 41 for Program Change and on page 37 for Control
Change). However, as previously explained, in case you
set the Transmit Channel on both units to one of 10 to 16
(dedicated to Auto Accompaniment), Voice selection of
yours and that of Auto Accompaniment will run against
each other.
Additionally, for controlling Tempo, or Start/Stop of
Recording/Playback from the external keyboard, follow the
same step in "Controlling Auto Accompaniment by External
Keyboard".
« Example 3 » when using a Drum Machine or Pad
Controller
First, you set the Transmit Channel of the Drum Machine to
«16», and set each Transmit Note number same as the one
corresponding to the PSS-795's Percussion sound you
wish, refering to the correspondence list on page 41. When
you play the Drum Machine, the Percussion sounds of
PSS-795 will be reproduced by the performance data
including Strength and Weakness (according to Velocity
data).
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 96 PERCUSSIONS) from
the Drum Machine (or other Master device), or (B) assign
the Voice number 96 PERCUSSIONS for the same
Channel on the PSS-795 following the methods in " Voice
Selection on Each Receive Channel" on page 39. Then set
the Transmit Note number on the Drum Machine as already
mentioned.
« 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-795, and assign the 1st PSS-795
(Receive Channels 1-8/Enable, the rest/Disable) and
assign the 2nd PSS-795 (Receive Channnels 9-16/Епа
the rest/Disable). If you use two PSS-795s dividing their ^
Receive Channels like this, you can have them play in 56
Polyphonic Sounds capability.
2nd PSS-795
Receive Channel: 9-16 7%
1st Р55-795
Receive Channel: 1-8 Enable
< Example 5 > when controlling an external Sound
Module from PSS-795
If you set the Sound program number of the external Sound
Module which matches to a MIDI Program Change Number
of PSS-795 beforehand, you can do the external Sound
program selections PSS-795. In this case, if you select a
similar Sound Program to a PSS-795's Voice and the
Sound Module has Multi-Timbre mode, you can also apply
Song Memory or Auto Accompaniment function to the
Module.
