Page 2: Principle Of Operation
We already connect these jumpers for you. In the case of the Korg Lambda there is 1 common signal. Installation Before you place the boards please stick insulation tape on the bottom side of the boards to prevent short circuits with the tinfoil.
Page 3 Now solder the switch board wires to the key contacts: Take care that you don’t accidentally desolder the internal wires. Switch board 1 (20pin connector): Wire 1 gets soldered to the common connection (bus bar). Wire 2 gets cut. Wires 3 – 18 get soldered to key contacts 1 – 16. Wires 19 and 20 get cut.
Page 4: Power Connection
Power connection You need to extend the wires of the power connector by about 20cm. To do so take some stranded wire with different colors, strip and solder to the power connector wires. Use shrinking tube to cover the joints. Then solder the wires to the power supply board.
Page 5 Installing the midi socket Decide where you want to install the MIDI socket. Use the provided drill guide to center punch the locations of the 3 holes. The two small holes need to be about 3.5mm in diameter, the large hole 15mm.
