Kurzweil MPS10 - The Function Button Pair; Function Mode Parameters

When using the MPS10 with a computer via MIDI, the MPS10 may
play the same note twice-noce by the direct sound engine
connection and once by the“echo”through the sequencer and
coming back. You can eliminate the echoing of notes by setting
default setting is“On”.
