Page 2: Principle Of Operation
Principle of operation OrganDonor uses analog switches to simulate keyboard presses directly. Normally this would require to solder two wires for each key. Luckily this can often be avoided by grouping common signals. OrganDonor features solder jumpers to connect common signals on the back of each analog switch board. - Page 3 Switchboard 1 20pin Header – make sure to install the header on the top side of the board. Solder the jumpers on the backside of the board as shown. Switchboard 2 16pin Header – make sure to install the header centered on the top side of the board.
- Page 4 Switchboard 3 16pin Header – make sure to install the header centered on the top side of the board. Solder the jumpers on the backside of the board as shown. Switchboard 4 (Single Switch) We already soldered the jumper on this board, you can use it as is.
- Page 5 Switch board installation Mount the switch boards and the main board on the bottom plate of the synthesizer as shown in in the picture using the 15 2,9x4,5mm screws. The switchboards are mounted in reverse order to keep cable length short.

Page 6: Power Connection
Power connection Unplug the two connectors on the power supply pcb. Remove the 4 screws holding the pcb. Flip the pcb away from you so you have access to the bottom side. Solder the wires of the power cable assembly as shown in the picture. Take care not to create solder bridges. - Page 7 Installing the switch contacts As the switch boards are installed in reverse order switch 1 triggers the highest note and switch 49 triggers the lowest note. That also means that the key assignment is in reverse order. Keep that in mind should you wish to play with the configuration! Cut the ribbon cables to length and strip the wires.
- Page 8 Switch board 2: Wires 1-16 get soldered to key contacts 33-18. Switch board 3: Wires 1-16 get soldered to key contacts 17-2. Switch board 4 (single): The single wire gets soldered key contact 1. Installing the midi socket The midi socket can be installed on the back of the machine. Use the provided drill guide to center punch the locations of the 3 holes.
- Page 9 The configuration tool can also be used to experiment with settings and key assignments.
