4.1. SAMPLE DUMP STANDARD
Transmission is performed when you execute the Sample Editor command “Bulk” with the Standard
format, or when a Sample Dump Request is received.
The A3000 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.
Messages will be valid when their channel number matches the device number.
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.

When this message is received, the A3000 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.
