Yamaha Personal Electronic Piano YPP-15 - Manual (Page 14)

If you set up a Hand-Shaking connection between
the YPP-15 and the sequencer, there are two things
to be noted:
If the sequencer is set to transmit the same MIDI infor­
mation as received at its MIDI IN jack (This is called
“Echo On”, “Soft Thru On”, etc., depending on the
make), set the YPP-15 to “Local Control Off If you
fail to do this, pressing a single key will sound twice as
many notes as in normal play. As a result, it will reduce
the polyphonic notes you can play at a time.
Conversely, when the sequencer is set to “Echo Off”
(“Soft Thru Off”, etc.), you cannot play directly from the
keyboard If it is in “Local Control Off”, because the
sequencer doesn’t retransmit any received MIDI data. In
this case, you have to set the YPP-35 to “Local Control
On”, which enables you to control the sound module
from either the keyboard or the sequencer.

(*1) Local Control On/Off: Normally, the YPP-15’s
keyboard is connected to its internal sound module,
which means that when you play, a sound is output
from the instrument, and when you select a different
voice, the sound changes. This state is called “Local
Control On”. However, if desired, the YPP-15 can
be set to “Local Control Off.” In this state, the
keyboard is disconnected from the sound module,
which means that if you play something, a sound will
not be produced from the instrument itself, but your
performance can be transmitted via MIDI to an
external instrument.
- Setting to Local Control Off
While holding down the MIDI/TRANSPOSE button,
press Voice Select button PIANO 1. To return the
YPP-15 to Local Control On, repeat the same pro­
cedure.
One of the most exciting features of the YPP-15 is
that it is capable of playing all of its five voices at the
same time. This feature is called Multi-timbre, and
is most useful when using the YPP-15 as a Slave
from a sequencer.
The YPP-15 has two play modes: Normal and Multi­
timbre. When the instrument is turned on, it is
always in Normal mode, that is, you play a single
voice on the keyboard. When in Multi-timbre mode,
however, the YPP-15 will act as ten independent
sound modules, with all 5 preset voices available for
use in an ensemble performance.
- Entering Multi-timbre mode
While holding down the MIDI/TRANSPOSE button,
press the HARPSICHORD Voice Select button. To
exit from Multi-timbre mode, repeat the same op­
eration once again.
Now, try using the YPP-15 in Multi-timbfe mode with
a sequencer(*).
* To best use the YPP-15 in Multi-timbre mode, you will
need a Master device which can control other devices
with different MIDI channels at the same time. This could
be a sequencer, MIDI-equipped personal computer, or
MIDI master keyboard.
The following diagram relates to a Hand-Shaking
connection between a YPP-15 and a sequencer.
Try going quickly through the following steps, to
become familiar with the use of Multi-timbre mode.
The object is to record an ensemble performance of
several parts onto the sequencer, then play it back
with each part sounding in a different YPP-15 voice.
