Yamaha YPP-100 F7

YPP-100

The Function Mode

•Always use a high-quality MIDI cable to connect MIDI OUT to MIDI IN terminals. Never use MIDI

cables longer than about 15 meters, since cables longer than this can pick up noise which can cause

data errors.

F7 MIDI Functions

F7.1: MIDI Transmit Channel Selection...............................................................................

F7.2: MIDI Receive Channel Selection.................................................................................

The MIDI system allows transmission and reception of MIDI data on 16 different chan-

nels. Multiple channels have been implemented to allow selective control of certain instru-

ments or devices connected in series. For example, a single MIDI sequence recorder could be

used to “play” two different instruments or tone generators. One of the instruments or tone

generators could be set to receive only on channel 1, while the other is set to receive on

channel 2. In this situation the first instrument or tone generator will respond only to channel-

1 information transmitted by the sequence recorder, while the second instrument or tone

generator will respond only to channel-2 information. This allows the sequence recorder to

“play” two completely different parts on the receiving instruments or tone generators.

In any MIDI control setup, the MIDI channels of the transmitting and receiving equipment

must be matched for proper data transfer. A “Multi-timbre” receive mode is also available,

which allows simultaneous reception of different parts on all 16 MIDI channels, allowing the

YPP-100 to play multi-channel song data received from a music computer or sequencer.

There’s also a “1-2” mode which allows simultaneous reception on channels 1 and 2.

Use the [–/NO] and [+/YES] buttons to select the desired transmit or receive channel. The

transmit channel parameter can also be turned “OFF” if you don’t want the YPP-100 to

transmit any MIDI data. To select the multi-timbre receive mode, set the receive channel to

“ALL”. Select “1-2” for multi-timbre reception on channels 1 and 2 only.

Press the [–/NO] and [+/YES] buttons simultaneously to recall the default setting: transmit

= “1”; receive = “ALL”.

•In the dual mode, first voice data is transmitted on its set channel while second voice data is transmit-

ted on the next greater channel. No data is transmitted if the transmit channel is set to “OFF”.

•Demo/preset song data and recorder playback data are not transmitted via MIDI.

•No MIDI reception occurs when the demo/preset song mode is engaged.

•Program change and other like channel messages received will not affect the YPP-100’s panel

settings or what is being played on the keyboard.
