Roland Music Atelier AT-100 Midi Implementation Manual

MIDI Implementation

1. Receive Channel

■ Performance Parts and Transmission Channels
This instrument contains two sound generators: one for SMF data playback (GM2/GS) and one for
keyboard performance. Normally, data received at the MIDI In connector will control only the
sound generator for SMF data playback. However by changing the MIDI IN Mode setting, you can
also control the keyboard sound generator from MIDI In.
For instructions on changing the MIDI IN mode, refer to the Owner's Manual. For instructions on
controlling each sound generator, refer to the "Received data" section.
* In this document, the Music ATELIER AT-900/900C/800/500/300/100/75 models are collectively
referred to as "the ATELIER."
❍MIDI IN MODE
Mode Explanation
MODE 1 Control the instrument as a GM2/GS sound generator.
MODE 2 Channels 5 through 10 and Channels 12,14,15 are transmitted to the GM2/
GS sound generator, and all other channels are transmitted to the
keyboard sound generator. When the Pedal part tone has been selected,
Channel 2 is transmitted to the sound generator used for the keyboard
performance; if no tone has been selected, it is transmitted to the GM2/GS
sound generator.
The correspondence between channels and parts in each mode is described below.
Channel MODE1
1 GM2/GS
2 GM2/GS
3 GM2/GS
4 GM2/GS
5-10 GM2/GS
11 GM2/GS
12 GM2/GS

14-15 GM2/GS
16 GM2/GS
* The AT-300/100/75 do not have Manual Percussion.
■ MIDI Channels on SMF Music Data
This instrument contains two sound generators. Commercial SMF music data is played back using
the GM2/GS sound generator. The correspondence between channels and tracks when the AT's
Track Mute function is used is described below.

SOLO 1
When SMF music data created using the ATELIER is used, the parts of the performance played by
hand are transmitted to the sound generator used for the keyboard performance, and the
automatic accompaniment portions (rhythm performances, Arranger) are transmitted to the
GM2/GS sound generator.
The correspondence between channels and parts for SMF music data created using the ATELIER is
described below.

2. Transmit Channel
■ Keyboard and Transmit Channel
You can control external MIDI devices using the ATELIER's MIDI Out connector. Data describing
what is played on the Upper keyboard, the Lower keyboard, and the pedalboard is transmitted
over MIDI channels for the respective parts. Messages from the ATELIER's expression pedal and PC
Numbers set in the Registrations are transmitted on the Control channel. The channels used for
transmission can be changed individually for each Registration. For instructions on how to change
the transmission channels, refer to the Owner's Manual.
Channel (default) Content Transmitted
Upper (4) Key information from the Upper keyboard is transmitted.
Lower (3) Key information from the Lower keyboard is transmitted.
Pedal (2) Performance information from the pedalboard is
transmitted.
Solo (1) When "Solo to Lower" is set to ON, Solo part key information
from the Lower keyboard is transmitted.
Control (16) Expression pedal information and PC Numbers set in the
Registrations are transmitted.
* The PC Number is transmitted when Send PC Switch is set to ON.
* For more details regarding the data that is transmitted, refer to "Transmit data" (p. 8).
3. Receive Data
[GM2] This indicates that the message will be received if the MIDI IN Mode is
MODE 1 and the unit is in GM2 mode. Use GM2 System On (p. 5) to select
GM2 mode.
[GM1] This indicates that the message will be received if the MIDI IN Mode is
MODE 1 and the unit is in GM1 mode. Use GM1 System On (p. 5) to select
GM1 mode.
[GS] This indicates that the message will be received if the MIDI IN Mode is
MODE 1 and the unit is in GS mode. Use GS Reset (p. 5) to select GS mode.
[AT] This indicates that the message will be received on the keyboard part if the
MIDI IN Mode is MODE 2. For details on the keyboard part, refer to "Receive
channel" (p. 1).
■ Channel Voice Messages
●Note off [GM2] [GM1] [GS] [AT]
Status 2nd byte
8nH kkH
9nH kkH
n = MIDI channel number:
kk = note number:
vv = note off velocity:
* For Drum Parts, these messages are received when Rx.NOTE OFF = ON for each Instrument
[GS].
* The velocity values of Note Off messages are ignored.
●Note on [GM2] [GM1] [GS] [AT]
Status 2nd bytes
9nH kkH
n = MIDI channel number:
kk = note number:
vv = note on velocity:
* Not received when Rx.NOTE MESSAGE = OFF [GS]. (Initial value is ON)
* For Drum Parts, not received when Rx.NOTE ON = OFF for each Instrument [GS].
●Polyphonic Key Pressure [GS]
Status 2nd bytes
AnH kkH
n = MIDI channel number:
kk = note number:
vv = key pressure:
* Not received when Rx.POLY PRESSURE (PAf) = OFF [GS]. (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial settings,
there will be no effect [GS].
* Not Received in Keyboard Part.
