12

The numbers are as follows:

91 – Reverb Level 92- Reverb Type Select (0,1, 2) 93 – Chorus Level 94 – Chorus Type Select (0, 1)

Digital effects are sent out over MIDI, using controller messages 91 for reverb, and 93 for chorus Because ProKeys always sends

the current effect values, it can be used to control the reverb/chorus amount in any midi device that can receive these controllers.

Programs will maintain their correct effects when responding to incoming MIDI information as the settings are stored with the

programs.

MIDI Control Section

After pressing the program button, pressing the (+) or (-) button will send the program change immediately.

For more information on Program Changes, please see page 14.

Bank LSB/MSB Buttons

These buttons have an identical use to the Program Button except that they send Bank LSB or Bank MSB Messages respectively.

These messages are used to select different banks of programs in your MIDI device. As with the Program Button, Bank Messages

are sent immediately.

Channel Button

This alters the transmit channel of the keyboard. The channel is not updated until a valid entry has been made and normal mode

resumes. When the Channel Button is pressed, note- off messages for all notes are sent out to prevent a “stuck-note” situation

where a note off is sent to a new channel for a note on sent on the previous channel (which causes a hanging note that never ends

Local On/Off Dual Buttons

Pressing the Channel and Program Buttons at the same time toggles the Local Mode on and off. When these buttons are pressed

at the same time, the LED will display ‘on’ or ‘off’ accordingly. The default setting is ‘on.’

If Local is turned off, the keyboard will no longer play the internal audio instrument sounds, but can still be used to play the sounds

of external MIDI synthesizers. However, the internal audio continues to be accessible via external MIDI messages from external

sequencers.

MIDI Out from USB Dual Buttons

Pressing the Program and Bank LSB Buttons at the same time toggles MIDI Out from USB Mode on and off. If this mode is active,

the MIDI Out port transmits MIDI data received at the USB port instead of MIDI data that is generated internally by the device . As

with the local buttons, the LED will display ‘on’ or ‘off’ as these buttons are pressed at the same time.

currently assigned Program and Bank values.

Note: Although the Program, Bank LSB and Bank MSB Messages that are transmitted when these buttons are pressed can be

altered, this does NOT affect the Program Change required to access the 14 internal sounds from an external MIDI device.
