In actuality, automix will start when the next TIMING CLOCK is received after receiving the CONTINUE message. STATUS 11111011 FB Continue 2.9 STOP (FC) Reception This message is received if the automix TIME REFERENCE setting is MIDI CLOCK, and will cause automix to stop. STATUS 11111100 FC Stop 2.10 ACTIVE SENSING (FE) Reception Once this message has been received, the failure to receive any message for an interval of 400 ms or longer will cause MIDI transmission to be initialized, such as by clearing the Running Status. STATUS 11111110 FE Active sensing 2.11 SYSTEM RESET (FF) Reception When this message is received, MIDI communications will be cleared, e.g., by clearing the Running Status. STATUS 11111111 FF System reset 2.12 SYSTEM EXCLUSIVE MESSAGE (F0) 2.12.1 MIDI MACHINE CONTROL (MMC) These messages are transmitted when the Machine Control section of the DM1000 is operated. 2.12.2 BULK DUMP This message sends or receives the contents of various memories stored within the DM1000. The basic format is as follows. For DUMP DATA F0 43 0n 7E cc cc tt mm mm [Data …] cs F7 For DUMP REQUEST F0 43 2n 7E tt mm mm F7 n Device Number cc cc DATA COUNT (the number of bytes that follow this, ending before the checksum) 4C 4D 20 20 38 43 39 31 Model ID tt DATA TYPE mm mm DATA NUMBER cs CHECK SUM A unique header (Model ID) is used to determine whether the device is a DM1000. CHECK SUM is obtained by adding the bytes that follow BYTE COUNT (LOW) and end before CHECK SUM, taking the binary compliment of this sum, and then setting bit 7 to 0. CHECK SUM = (-sum)&0x7F Reception This message is received if [Bulk RX] is ON and the [Rx CH] matches the device number included in the SUB STATUS. When a bulk dump is received, it is immediately written into the specified memory. When a bulk dump request is received, a bulk dump is immediately transmitted. DM1000—Bedienungsanleitung MIDI-Datenformat 355 MIDI-Datenformat 355 This message is transmitted on the [Tx CH] by key operations in the [MIDI]-[ BULK DUMP] screen. A bulk dump is transmitted on the [Rx CH] in response to a bulk dump request. The data area is handled by converting seven words of 8-bit data into eight words of 7-bit data. Conversion from actual data into bulk data d[0~6]: actual data b[0~7]: bulk data b[0] = 0; for( I=0; I<7; I++){ if( d[I]&0x80){ b[0] |= 1<<(6-I); } b[I+1] = d[I]&0x7F; } Restoration from bulk data into actual data d[0~6]: actual data b[0~7]: bulk data for( I=0; I<7; I++){ b[0] <<= 1; d[I] = b[I+1]+(0x80&b[0]); } 2.12.2.1 Scene memory bulk dump format (compress) The DM1000 can transmit and receive scene memories in compressed form.
