Mute switches, scene memo- ries, and muting can be controlled by a MIDI keyboard or sequencer. When using a MIDI sequencer synchronized to a recorder, the mute switches on the 2412 may be synchronized as well. This is an excellent feature during mixdown operations when rapid and varied muting sequences are required. The MIDI controls may be programmed allowing you to sequence the mutes accurately in real time. While these procedures may initially seem complex, with a little practice they are very easy. Please use the following information to set up the 2412 for MIDI control operations. MIDI Interface The 2412 MIDI interface The 2412 has various MIDI functions. It can: ■ receive a PROGRAM CHANGE, and change snap shot patterns. ■ receive a NOTE ON/OFF or the CONTROL CHANGE message, change muting ON or OFF, and control the L-R, PAN switches. receive a CONTROL CHANGE message and automatically store the status of the mute, L-R, PAN switches to scenes A through D memory. Setting up a MIDI channel The 2412 uses the mute switch of the input module for setting the MIDI channel. To set the MIDI channel for either transmitting or receiving, while pressing the mute switch of the channel that you wish to set, turn the power on. This process will set the MIDI channel. dnput module channel 5> Example: Setting the MIDI channel to "five”. While pressing the mute switch of channel five, turn the power on. • If the power is turned on without pressing a mute switch, the MIDI channel will automatically be set to 1. • When pressing multiple switches, the MIDI channel is assigned to the smallest number. • When initially turning on the power, the 2412 will be in the OMNI "OFF" mode. In the OMNI "OFF" mode, the 2412 receives only one set channel MIDI message. After receiving an OMNI "ON" message, the 2412 will enter the OMNI "ON" mode. In the OMNI "ON" mode, the 2412 can receive "all channel" MIDI messages. Rccall and dear the mute pattern by PROGRAM CHANGE By sending a PROGRAM CHANGE message to the MIDI IN connector, the 2412 can recall snap shot patterns stored in memory scenes A through D. Programs number one through four are each applied to scenes A through D. Applying program number zero will clear the recalled memory. Program change byte composition of program number "3 Cnh 03 h _ This will indicates "program number=3" (MIDI channel) This is the status byte of the program change. * Each byte ”h" indicates the hexadecimal. * Please refer to the specific MIDI equipment manual for further information. < NOTE > Scene A, when assigned to program number "1", is not "0". Pressing the scene keys recalls the memories and outputs the program change messages of the program number that is applied to the scene memory from the MIDI OUT connector (when the store and preview indicators are extinguished). Pressing the STORE and PREVIEW buttons clears the recalled memory and outputs the program change messages. Setting the MUTE, L-R, PAN switches to ON/OFF Initializing Procedure When controlling MUTE, L-R, and PAN switches by MIDI messages, the 2412 may be switched to either NOTE ON/OFF or CONTROL CHANGE. < NOTE > When turning on the power, the 2412 automatically enters the NOTE ON/OFF message mode. If you are using NOTE ON/OFF messages only, the following operations are not necessary. 4 :: MIDI Interface :i ; When assigning NOTE message mode control, transmit the CONTROL CHANGE message to the 2412 as follows: Byte composition of CONTROL CHANGE message Bnh OOh OOh -Indicates "Control number = 0" -Indicates "Value = 0". _ This is the status byte of the CONTROL (n = MIDI channel) * Each byte "h" indicates the hexadecimal. * Please refer to the specific MIDI equipment manual for the writing and transmitting of CONTROL CHANGE messages. Example 1: When setting the 2412 MIDI channel to "8": Transmit to the 2412 llBlBiijillMBSpi Example 2: When setting the 2412 MIDI channel to "12”: Transmit to the 2412 =' Selecting the CONTROL CHANGE message When assigning the control mode with the CONTROL CHANGE message, transmit the CONTROL CHANGE message as follows to the 2412. MIDI Interface The "xx" range of the 2412 MIDI commands is 19h to 60...
