STATUS 11110010 F2 Song position pointer DATA 0vvvvvvv vv Song position LSB 0vvvvvvv vv Song position MSB 7. TIMING CLOCK (F8) Reception If the automix TIME REFERENCE setting is MIDI CLOCK, this message is used to synchronize automix. It is also used to control effects. This message is transmitted 24 times per quarter note. STATUS 11111000 F8 Timing clock 8. START (FA) Reception This message is received if the automix TIME REFERENCE setting is MIDI CLOCK, and will start the automix. In actuality, automix will start when the next TIMING CLOCK is received after receiving the START message. STATUS 11111010 FA Start 9. CONTINUE (FB) Reception This message is received if the automix TIME REFERENCE setting is MIDI CLOCK, and will cause automix to start from the current song position. In actuality, automix will start when the next TIMING CLOCK is received after receiving the CONTINUE message. STATUS 11111011 FB Continue 10. 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 DM2000 Version 2—Manual de Instrucciones Format Details 383 Format Details 383 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 12. 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 13. SYSTEM EXCLUSIVE MESSAGE (F0) 13.1 MIDI TIME CODE (FULL MESSAGE) The Automix synchronizes these messages when they are received at a port specified by the TIME REFERENCE setting. 13.2 MIDI MACHINE CONTROL (MMC) These messages are transmitted when the Machine Control section of the DM2000 is operated. 13.3 BULK DUMP This message sends or receives the contents of various memories stored within the DM2000. 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) Model ID (for DM2000, 4C 4D 20 20 38 43 31 32) tt DATA TYPE mm mm DATA NUMBER cs CHECK SUM A unique header (Model ID) is used to determine whether the device is a DM2000. 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 The DM2000 can transmit and receive BULK data only if the size of a MIDI packet (F0 - F7) is 4096 bytes or smaller. If large data consists of multiple MIDI packets, they can be transferred sequentially. 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. Transmission 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]); } 13.3.1 Scene memory bulk dump format (compressed data) The DM2000 can transmit and receive scene memories in compressed form.
