3.3 Dump Request When the DTXTREME IIs receives dump request (reception only), it transmits requested bulk data. $F0 $43 $7D $2n $44 $54 $58 $54 type1 type2 type3 type4 numM numL $F7 n: device number ID, ASCII char 'D' ID, ASCII char 'T' ID, ASCII char 'X' ID, ASCII char 'T' type, ASCII char type, ASCII char type, ASCII char type, ASCII char object number MS7bit object number LS7bit Type specifies the type of bulk data. See the bulk dump format for available types. Object number specifies a unique number from multiple similar kinds of data (like drum kit number, song number or so on). If the target data is single (like system common data, edit buffer data or so on), this value must be $7F $7F ($3FFF). If the target data is a song, the DTXTREME IIs will not respond to $7F $7F ($3FFF). 4. System Common Messages 4.1 Song Select $F3 $nn nn is song number. Reception only. 5. System Realtime Messages Supports both transmission and reception. 5.1 Timing Clock When the "MIDI sync mode" system parameter has a value of "ext" or "auto," the DTXTREME IIs synchronizes to incoming timing clock. 5.2 Start, Continue, Stop When the "MIDI control" system parameter is set to off, the DTXTREAME IIs does not receive start, continue and stop messages. 5.3 Active Sensing Reception: If an active sensing message is received and there is no subsequent MIDI data coming in for more than approximately 300 milliseconds, the DTXTREAME IIs will mute all current sounds playing. Transmission: The DTXTREME IIs transmits MIDI data including active sensing message every (approximately) 300 milliseconds. 6
