ENGLISH F8. MIDI Functions You can make detailed adjustments to MIDI settings. For more information about MIDI, see the "About MIDI" section (page 44). The [HOST SELECT] switch on the bottom surface must be set to "MIDI" to enable the MIDI connectors. When you use the [TO HOST] connector, set the [HOST SELECT] switch to the appropriate position for the type of computer you are using (pages 44-48). In this situation, all MIDI settings described below will affect the MIDI signal in and out of the [TO HOST] connector. 1. Engage Function mode and select . 2. Press the [+/YES] button to engage the MIDI function's sub-mode, then use the [TEMPO/ FUNCTION# ▼, ▲] buttons to select the desired sub-mode. Press the [-/NO] or [+/YES] button to set a selected parameter. Sub-mode F8.1: MIDI Transmit Channel Selection In any MIDI control setup, the MIDI channels of the transmitting and receiving equipment must be matched for proper data transfer. This parameter enables you to specify the channel on which the P-90 transmits MIDI data. Setting range: 1 - 16, OFF (not transmitted) Normal setting: 1 In Dual mode, Voice 1 data is transmitted on its specified channel. In Split mode, right voice data is transmitted on its specified channel. In Dual mode, Voice 2 data is transmitted on the next greater channel number relative to the specified channel. In Split mode, left voice data is transmitted on the next greater channel number relative to the specified channel. In either mode, 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. F8.2: MIDI Receive Channel Selection In any MIDI control setup, the MIDI channels of the transmitting and receiving equipment must be matched for proper data transfer. This parameter enables you to specify the channel on which the P-90 receives MIDI data. Setting range: ALL, 1&2, 1 - 16 Normal setting: ALL ALL: A "Multi-timbre" Receive mode is available. It allows simultaneous reception of different parts on all 16 MIDI channels, enabling the P-90 to play multi-channel song data received from a music computer or sequencer. 1&2: A "1&2" Receive mode is available. It allows simultaneous reception on channels 1 and 2 only, enabling the P-90 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-90's panel settings or the notes you play on the keyboard. No MIDI reception occurs when Demo/Preset Song mode is engaged. F8.3: Local Control ON/OFF "Local Control" refers to the fact that, normally, the P-90 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 P90 keyboard does not play the internal voices, but the appropriate MIDI information is still transmitted via the MIDI OUT connector when notes are played on the keyboard. At the same time, the internal tone generator responds to MIDI information received via the MIDI IN connector. Setting range: ON/OFF Normal setting: ON 40 P-90 Detailed Settings - [FUNCTION]
