* For Drum Parts, these messages are received when Rx.NOTE OFF = ON for each

Instrument.

* The velocity values of Note Off messages are ignored.

Status 2nd bytes 3rd byte BnH 54H kkH

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

*A Note-on received immediately after a Portamento Control message will change

continuously in pitch, starting from the pitch of the Source Note Number.

* If a voice is already sounding for a note number identical to the Source Note Number,

this voice will continue sounding (i.e., legato) and will, when the next Note-on is received, smoothly change to the pitch of that Note-on.

* The rate of the pitch change caused by Portamento Control is determined by the

Portamento Time value.

Example 1. On MIDI (Description) Result 90 3C 40 (Note on C4) C4 on B0 54 3C (Portamento Control from C4) no change 90 40 40 (Note on E4) glide from C4 to E4 80 3C 40 (Note off C4) no change 80 40 40 (Note off E4) E4 off

Example 2. On MIDI (Description) Result B0 54 3C (Portamento Control from C4) no change 90 40 40 (Note on E4) E4 is played with glide from C4 to E4 80 40 40 (Note off E4) E4 off

NRPN MSB/LSB (Controller number 98, 99)

Status 2nd bytes 3rd byte BnH 63H mmH BnH 62H llH

n = MIDI channel number: 0H-FH (ch.1-ch.16) mm = upper byte of the parameter number specified by NRPN ll = lower byte of the parameter number specified by NRPN

* NRPN can be received when Rx.NRPN = ON. “Rx.NRPN” is set to OFF by power-on

reset or by receiving “Turn General MIDI System On,” and it is set to ON by “GS

RESET.” * The value set by NRPN will not be reset even if Program Change or Reset All Controllers

is received. * Not Received in Keyboard Part.

**NRPN** The NRPN (Non Registered Parameter Number) message allows an extended range of control changes to be used. To use these messages, you must first use NRPN MSB and NRPN LSB messages to specify the parameter to be controlled, and then use Data Entry messages to specify the value of the specified parameter. Once an NRPN parameter has been specified, all Data Entry messages received on that channel will modify the value of that parameter. To prevent accidents, it is recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished setting the value of the desired parameter. Refer to Section 4. Supplementary material “Examples of actual MIDI messages” <Example 4> (p. 12). On the GS devices, Data entry LSB (llH) of NRPN is ignored, so it is no problem to send Data entry MSB (mmH) only (without Data entry LSB).

On the AT-S, NRPN can be used to modify the following parameters.

NRPN Data entry MSB LSB MSB Description 01H 08H mmH Vibrato rate (relative change on specified channel)

mm: 0EH-40H-72H (-50 - 0 - +50)

regardless of the preset value.

RPN MSB/LSB (Controller number 100, 101)

Status 2nd bytes 3rd byte BnH 65H mmH BnH 64H llH

n = MIDI channel number: 0H-FH (ch.1-ch.16) mm = upper byte of parameter number specified by RPN ll = lower byte of parameter number specified by RPN

* Not received when Rx.RPN = OFF. (Initial value is ON) * The value specified by RPN will not be reset even by messages such as Program Change

or Reset All Controller.

**RPN** The RPN (Registered Parameter Number) messages are expanded control changes, and each function of an RPN is described by the MIDI Standard. To use these messages, you must first use RPN MSB and RPN LSB messages to specify the parameter to be controlled, and then use Data Entry messages to specify the value of the specified parameter. Once an RPN parameter has been specified, all Data Entry messages received on that channel will modify the value of that parameter. To prevent accidents, it is recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished setting the value of the desired parameter.Refer to Section 4. “Examples of actual MIDI messages” <Example 4> (p. 12).

On the AT-S, RPN can be used to modify the following parameters.

16384 (the value of Control Number 0 is other than 0 (00H)).

The System Exclusive Messages received by the AT-S are; messages related to mode settings, Universal Realtime System Exclusive messages and Data Set (DT1).

System exclusive messages related to mode settings

These messages are used to initialize a device to GS or General MIDI mode, or change the operating mode. When creating performance data, a “GM2 System On” or “GM1 System On” message should be inserted at the beginning of a General MIDI score, and a “GS Reset” message at the beginning of a GS music data. Each song should contain only one mode message as appropriate for the type of data. (Do not insert two or more mode setting messages in a single song.)

Data transmission

AT-S can receive the various parameters using System Exclusive messages. The exclusive message of GS format data has a model ID of 42H and a device ID of 10H (17), and it is common to all the GS devices.

Data set 1DT1

This is the message that actually performs data transmission, and is used when you wish to transmit the data.

Status Data byte Status F0H 41H, 10H, 42H, 12H, aaH, bbH, ccH, ddH, ... eeH, sum F7H

Byte Explanation F0H Exclusive status 41H ID number (Roland) 10H Device ID 42H Model ID (GS) 12H Command ID (DT1) aaH Address MSB: upper byte of the starting address of the transmitted data bbH Address: middle byte of the starting address of the transmitted data ccH Address LSB: lower byte of the starting address of the transmitted data ddH Data: the actual data to be transmitted. Multiple bytes of data are

transmitted starting from the address. :: :: eeH Data sum Checksum F7H EOX (End Of Exclusive)

* The amount of data that can be transmitted at one time depends on the type of data, and

data can be received only from the specified starting address and size. Refer to the Address and Size given in Section 3 (p. 8).

* Data larger than 128 bytes must be divided into packets of 128 bytes or less. If “Data Set

1” is transmitted successively, there must be an interval of at least 40 ms between packets.

* Regarding the checksum please refer to section 4 (p. 13).
