MIDI FUNCTIONS

Function Parameters

No.	Parameter Name	Display Name	Range/Settings
81	Remote Channel	RemoteCh	off, 01 - 16

This determines how the PortaTone is controlled by a “remote” (external) MIDI keyboard.

Set this to one of the 16 channels (01 - 16) for using an external keyboard to remotely control the PortaTone functions over the selected channel. (The remaining 15 channels can be used for multi- timbral operation.)

When this is set to “off,” the PortaTone can be used as a full 16-channel multi-timbral sound source. The default setting is “off.”

82 Keyboard Out KbdOut on/off

This determines whether the keyboard performance data of the PortaTone is transmitted or not.

When this is set to “off,” notes played on the PortaTone will not affect (not be transmitted to) the connected MIDI device. When this is set to “on,” the following keyboard data is transmitted: Main voice part over channel 1, Split voice part over channel 2, and Dual voice part over channel 11. The default setting is “on.”

If both Keyboard Out and Local Control (#84 below) are set to “off,” neither the connected MIDI device nor the PortaTone voices will sound when playing the keyboard.

83 Accompaniment Out AcmpOut on/off

This determines whether Auto Accompaniment data is transmitted via MIDI OUT or not.

When set to “on,” Auto Accompaniment data is transmitted over channels 3 - 10 (as listed below). The default setting is “on.”

Accompaniment Transmit Channels:

Channel 3	—	Bass
Channel 4	—	Chord part 1
Channel 5	—	Chord part 2
Channel 6	—	Pad
Channel 7	—	Phrase part 1
Channel 8	—	Phrase part 2
Channel 9	—	Rhythm part 2
Channel 10	—	Rhythm part 1

You can use Accompaniment Out in several ways. One useful application would be to play all or selected parts on a connected MIDI tone generator. In this way you could reinforce the PortaTone sounds by layering (or substituting) with the sounds of the tone generator. In a different application, you could record the individual parts from each channel to a sequencer, and use the comprehensive editing features of the sequencer to re-arrange the accompaniment parts.

84 Local Control Local on/off

This determines whether the keyboard is “connected” to the internal Voices of the PortaTone.

When set to “on,” the Voices respond to notes played from the keyboard. When set to “off,” the Voices respond only to incoming MIDI data (via MIDI IN). The default setting is “on.” If you are routing the MIDI OUT on the PortaTone to a sequencer and back to the MIDI IN, you may want to set this to “off” to avoid MIDI “feedback.”
