"Flash" is likely a typo for "Korg" (the manufacturer), or you may be looking for a "flash memory" save function (which this analog synth does not possess). The number "124" is likely a typo for the model number or part of a specific document ID. The most common models are the original Monotron , the Monotron Duo , and the Monotron Delay .
