MIDI data format MIDI data format 1. Functions 1.1 MIDI setup There are two types of serial connector: the MIDI connectors and the TO HOST connector. Each has the same functionality, and you can select either of these to use, depending on the type of device that will be connected. Both types use the MIDI format for communication. When using the TO HOST connector, you must select one of the three transmission methods listed below. Regardless of the type of connector you select, the MTC OUT connector will output MTC. Since the MTC transmitted from the MTC OUT connector is generated by hardware, its precision is very high. The MIDI OUT/THRU connector can be used as either THRU or OUT. If THRU is selected, the messages arriving at the MIDI IN connector will be re-transmitted without change from the MIDI OUT/THRU connector. Name Speed Applicable to PC1 31.25k for NEC PC9800 series PC2 38.4k for DOS/V,NEC PC9800 series Mac 31.25k for Macintosh (CLOCK=1MHz) 1.2 Scene change The settings of the [Program Change Assign Table] specify the scene that is recalled when a Program Change message is received. The settings of the [Program Change Assign Table] specify the program number that is transmitted when a scene is recalled. If more than one program number has been assigned to that scene memory number, the lowest-numbered program number will be transmitted. (If a memory number is recalled for which there is setting in the [MIDI Program Change Assign Table], the Parameter Change (Function Call) listed later in this section will be transmitted.) 1.3 MMC control These messages allow basic recorder operations such as STOP/PLAY/REC/LOCATE. If you select the MIDI SETUP menu item MMC MASTER, MMC commands will be transmitted according to the operation of the transport. If you select MMC SLAVE, the internal recorder will operate according to the received MMC commands. 1.4 Effect control Depending on the type of effect, note-on/off messages can be used for control. These settings are made for the parameters of each effect. 1.5 MIDI Clock transmission If the MIDI SETUP menu item [MIDI CLK] is ON, MIDI Clock messages will be transmitted during playback and recording. In MIDI Clock transmission mode, Song Position Pointer and Start/Stop/Continue commands will also be issued, and during playback or recording, MIDI Clock will be transmitted according to the MIDI Tempo Map. 1.6 MTC master If the MIDI SETUP menu item [MTC] is ON, MTC will be transmitted during playback and recording. MTC will always be transmitted from the MTC OUT connector regardless of the [MTC] setting. 1.7 MTC slave synchronization If the MIDI SETUP menu item [MTC SYNC] is set to SLAVE, the internal recorder will operate in synchronization to MTC messages received from the MIDI IN or TO HOST connector. 1.8 Realtime control of parameters The internal parameters can be input or output in realtime using control changes or parameter changes. 1.9 Transmission of scene memories or library data The bulk dump function can be used to send data to another device, or copy settings from another device to the AW2816. 1.10 MIDI Remote MIDI data created by the user can be transmitted from the AW2816 by operating its faders or ON keys. 2. AW2816 settings and operation 2.1 MIDI Setup 2.1.1 MIDI Channel 2.1.1.1 Transmit channel This sets the MIDI channel that will normally be used. However, transmission in response to a request will occur on the Receive Channel, in order to specify the desired that transmitted the request. 2.1.1.2 Receive channel This sets the MIDI channel that will be used for reception. MIDI messages are normally received only if the MIDI channel matches, but if OMNI is ON, they will be received regardless of the channel. 2.1.2 ON/OFF 2.1.2.1 Program change Enable/disable reception and transmission. If OMNI is turned ON, reception will occur regardless of the MIDI channel. If ECHO is ON, messages will be echoed regardless of the channel. 2.1.2.2 Control change Enable/disable reception and transmission. If OMNI is turned ON, reception will occur regardless of the MIDI channel. If ECHO is ON, messages will be echoed regardless of the channel. 2.1.2.3 Parameter change Enable/disable reception and transmission. If OMNI is turned ON, reception will occur regardless of the MIDI channel. If ECHO is ON, messages will be echoed regardless of the channel. 2.1.2.4 Bulk Enable/disable reception. 2.1.3 MMC Device ID Specify the ID number used to transmit and receive MMC commands. 402 Appendix
