There is a problem with the MIDI cable connections. Make sure that MIDI cables have not been pulled out or bro

37、ken. MIDI BUFFER FULL! More MIDI messages were received at once than the MC-307 was able to process. Reduce the amount of MIDI messages that are being transmitted to the MC-307. REC OVERFLOW! More recording data was received at once than the MC-307 was able to process. Reduce the amount of recording

38、 data that is being transmitted to the MC-307. CHECKSUM ERROR! The checksum value of the received system exclusive message is incorrect. Correct the checksum value. PTN REC FULL! Since the maximum number of notes that can be recorded in a single pattern has been reached, further pattern recording is

39、 not possible. Erase unneeded data from the pattern that you are recording. SONG REC FULL! Since the maximum number of patterns that can be registered in a single song has been reached, further song recording is not possible. A maximum of 50 patterns can be registered in a single song. No further pa

40、tterns can be registered. USER MEMORY FULL! Since there is insufficient user memory, the pattern cannot be saved. Either initialize an unneeded pattern. BEAT DIFFERS! Since a different time signature is set for the copy source and copy destination patterns, the pattern copy is not possible. The patt

41、ern copy operation can only be used for patterns with the same time signature. CANNOT ASSIGN! Since there are two or more un-muted parts, the phrase cannot be assigned to an RPS set. Decide on one part in the phrase that you wish to register, and mute all the other parts. NO QTZ SELECTED! Quantize i

42、s not selected. In the Play Quantize setting, select the quantization that you wish to use. EMPTY PATTERN! Since the pattern contains no musical data, it cannot be played back. CANNOT UNDO! Cannot undo. MEMORY DAMAGED! It is possible that the contents of internal memory have been damaged. Try executing the Factory Reset operation. If this does not resolve the problem, contact a nearby Roland service center. JAN, 2000MC-307 23
