MIDI IMPLEMENTATION Model: AT-S Series ❍Portamento Time (Controller number 5) Date: May. 8, 2002 Status 2nd bytes 3rd byte Version: 1.00 Bn H 05H vv H

1. Receive data n = MIDI channel number: 0H-FH (ch.1-ch.16) vv = Portamento Time: 00H-7FH (0-127), Initial value = 00H (0)

■Channel Voice Messages This adjusts the rate of pitch change when Portamento is ON or when using the

●Note off Portamento Control. A value of 0 results in the fastest change.

vv = Volume: 00H-7FH (0-127), Initial Value = 64H (100)

n = MIDI channel number: 0H-FH (ch.1-ch.16)

Volume messages are used to adjust the volume balance of each Part.

kk = note number: 00H-7FH (0-127)

Not received when Rx.VOLUME = OFF. (Initial value is ON)

vv = note on velocity: 01H-7FH (1-127)

Not Received in Keyboard Part.

Not received when Rx.NOTE MESSAGE = OFF. (Initial value is ON)

For Drum Parts, not received when Rx.NOTE ON = OFF for each Instrument. ❍Pan (Controller number 10) Status 2nd bytes 3rd byte Bn H 0AH vv H

(Center)

n = MIDI channel number: 0H-FH (ch.1-ch.16) kk = note number: 00H-7FH (0-127)

For Rhythm Parts, this is a relative adjustment of each Instrument’s pan setting.

Not received when Rx.PANPOT = OFF. (Initial value is ON) Not Received in Keyboard Part.

Not received when Rx.POLY PRESSURE (PAf) = OFF. (Initial value is ON) The resulting effect is determined by System Exclusive messages. With the initial
