ENGLISH MIDI Functions MIDI Functions You can make detailed adjustments to MIDI settings. MIDI Transmit/Receive Channel Selection In any MIDI control setup, the MIDI channels of the transmitting and receiving devices must be matched for proper data transfer. This parameter enables you to specify the channel on which the P-70 transmits or receives MIDI data. NOTE In Dual, Voice 1 data is transmitted on its specified channel and Voice 2 data is transmitted on the next greater channel number relative to the specified channel. In this case, no data is transmitted if the transmit channel is set to "OFF." Setting the Transmit Channel While holding down the [DEMO/SONG] and [GRAND PIANO/VOICE] buttons, press one of the C1-E2 keys. Setting the Receive Channel While holding down the [DEMO/SONG] and [GRAND PIANO/VOICE] buttons, press one of the C4-F5 keys.

This allows simultaneous reception of different parts on all 16 MIDI channels, enabling the P-70 to play multi-channel song data received from a music computer or sequencer. 1+2: "1+2" Receive. This allows simultaneous reception on channels 1 and 2 only, enabling the P-70 to play 1 and 2 channel song data received from a music computer or sequencer. Program change and other like channel messages received will not affect the P-70's panel settings or the notes you play on the keyboard. Data for the demo song and 50 piano preset songs cannot be transmitted via MIDI. "Local Control" refers to the fact that, normally, the P-70 keyboard controls its internal tone generator, allowing the internal voices to be played directly from the keyboard. This situation is "Local Control On," since the internal tone generator is controlled locally by its own keyboard. Local control can be turned OFF, however, so that the P-70 keyboard does not play the internal voices, but the appropriate MIDI information is still transmitted via the MIDI OUT terminal when notes are played on the keyboard. At the same time, the internal tone generator responds to MIDI information received via the MIDI IN terminal. While holding down the [DEMO/SONG] and [GRAND PIANO/VOICE] buttons, press the C6 key. Pressing the C6 key repeatedly toggles between Local Control On and Off. C6 C7 Default setting: ON 22 P-70 Owner's Manual
