Beyond the digital logic, the service manual pays profound attention to the of the instrument: the key-bed. The Pa700 features a semi-weighted key action designed for rapid arranger playing. The service manual dedicates full spreads to the rubber contact PCB (Printed Circuit Board) and the scanning matrix. In the world of vintage analog gear, a dead key might be a broken wire or a cold solder joint. In the Pa700, the manual reveals a "diode matrix" scanning system. This allows the single-chip CPU to read 61 keys using only a handful of wires. For the technician, this means that if an entire row of keys fails (e.g., C4 to B4), the problem is likely a broken trace or a dead diode at the edge of the PCB. If individual, isolated keys fail, the culprit is likely physical dirt or a torn rubber contact. The service manual thus translates a physical touch into a logical map, bridging the gap between human expression and machine code. Korg Pa700 Service Manual
