Appendix MIDI data format 1. Functions 1.1 MIDI-SETUP There are two types of serial connector: the MIDI connectors and the TO HOST. They have the same functionality, and you can select which type to use as appropriate for the connection destination. Both types use the MIDI format for communication. In the case of the TO HOST connector, the transmission method must be selected appropriate for the other device. The available methods are listed below. Regardless of which method is selected, MTC is transmitted from the dedicated MTC OUT connector. You can select either THRU or OUT as the function of the MIDI THRU/OUT connector. If THRU is selected, messages received at the MIDI IN connector will be retransmitted without change from the MIDI OUT/THRU connector. Name Connector Transmission speed Destination MIDI MIDI 31.25k for MIDI PC1 ToHost 31.25k for NEC PC9800series PC2 ToHost 38.4k for DOS/V Mac ToHost 31.25k for Macintosh (contain CLOCK) 1.2 SCENE CHANGE When a program change message is received, a scene will be recalled as specified by the [MIDI Program Change Assign Table]. Program change messages are transmitted with the program number specified by the [MIDI Program Change Assign Table]. If multiple program numbers are assigned to that memory number, the lowest-numbered program change will be transmitted. 1.3 MMC CONTROL Basic recorder operations such as stop/play/rec/locate can be controlled. If you select MMC MASTER from the MIDI SETUP menu, MMC commands will be transmitted according to operations of the transport. If you select MMC SLAVE, the internal recorder will operate according to the MMC commands that are received. 1.4 EFFECT CONTROL Depending on the effect type, note on/off messages can be received for control. These settings are made by the parameters of the corresponding effect. 1.5 MIDI CLOCK transmission If you select MIDI CLOCK transmission from the MIDI SETUP menu, MIDI clock messages will be transmitted during playback and recording. When the AW4416 is in MIDI clock transmission mode, Start/Stop/Continue commands will be transmitted by the corresponding operations, and MIDI Clock and Song Position Pointer messages will be transmitted according to the MIDI Tempo Map. 1.6 MTC master If you select MTC transmission from the MIDI SETUP menu, MTC will be transmitted during playback and recording. 1.7 MTC slave synchronization If you select SLAVE operation from the MIDI SETUP menu, the AW4416's internal recorder will operate in synchronization with the MTC messages received from the MIDI IN or TO HOST connector. 2. Internal settings and operations 2.1 MIDI-SETUP 2.1.1 MIDI Channel 2.1.1.1 Transmit channel Select the MIDI channel used for transmission. However, transmissions in response to requests are transmitted on the Receive Channel in order to specify the transmitting device. 2.1.1.2 Receive channel Specify the MIDI channel used for reception. In general, MIDI messages are received only if the MIDI channel matches, but this is not the case if OMNI is turned on. 2.1.2 ON/OFF 2.1.2.1 Program change Reception and transmission can be enabled or disabled. If OMNI is turned on, program changes will be received regardless of their MIDI channel. If ECHO is on, they will be echoed regardless of the channel. 2.1.2.2 Control change If ECHO is on, these messages will be echoed regardless of the channel. 2.1.3 MMC Device ID Specify the ID number used when transmitting and receiving MMC commands. 2.1.4 PORT Select whether serial communication will use the MIDI IN/ OUT connectors or the TO HOST connector. (MTC is always transmitted from the MTC OUT connector.) If the TO HOST connector is selected, you must also select one of three settings as appropriate for the other device. 2.1.5 THRU You can select whether the MIDI OUT/THRU connector will function as OUT or THRU. If THRU is selected, messages received at the MIDI IN connector will be retransmitted without change from the MIDI OUT/THRU connector. If MIDI THRU is selected, the connector will function as THRU regardless of the PORT setting. In order to function as MIDI OUT, the PORT setting must be set to MIDI IN/ OUT. 2.2 MIDI program change assign table The correspondence between program change numbers and scene numbers can be set freely. This conversion is applied to both transmission and reception. Appendix-50 - Reference Guide
