MIDI Data Format 3. Realtime messages 3.1. Reception 3.1.1. Active sensing Once active sensing is received, monitoring will begin, and if no MIDI input appears for an interval longer than approximately 400 msec, the MIDI receive buffer will be cleared, and the tone generator will be damped. 3.1.2 Timing Clock, Start, Continue, Stop When Program LFO Sync is set to MIDI, the LFO frequency and phase, the frequency of temposynchronized effects, and other time settings can be controlled via reception of Timing Clock ($F8), Start ($FA), CONTINUE ($FB) and STOP ($FC) messages. 4. UNIVERSAL SYSTEM EXCLUSIVE 4.1. SAMPLE DUMP STANDARD Transmission occurs when sample bulk dump is carried out using Format=SDS#nnnn or a Sample Dump Request is received. The A5000/A4000 will automatically detect whether the MIDI connections are an open loop or a closed loop, and will automatically switch to use or not use hand shaking. When the channel number and device number matches for each message that message is effective. The message is processed regardless of the device number when the received channel number is $7F. The sample number is in the range of 0-1024 (displayed as 1-1025), and samples will automatically be assigned to sample objects. For transmission, these numbers or the specified number will be used. For reception, sample numbers in the range of 0-16383 will be recognized, and the sample will be kept as"MIDI nnnnn" where sample number nnnnn is added to the name. 4.1.1. Dump Request 0 11110000 $F0 1 01111110 $7E 2 0nnnnnnn nnnnnnn = Channel Number 3 00000011 $03 4 0sssssss sssssss = Sample number(LSB first) 5 0sssssss sssssss = 6 01110111 $F7 When this message is received, the A5000/A4000 will search for the correspondingly-numbered sample, and if that sample exists, a dump header will be transmitted. If the corresponding sample does not exist, processing will be terminated. This message is not transmitted. 4.1.2.
