Page 2: 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 Switch board installation Mount the switch boards on the underside of the keyboard as shown in in the picture using the M3x16mm screws. The 3 left boards have 16 pin connectors, the last one on the right has a 20 pin connector! To mount the switchboard you need to unscrew the white plastic bracket.
- Page 4 After you removed the white plastic bracket it should look like this: Then take 1 of the M3x16mm screws and screw the switch board and the white plastic brackets back in place. Do that for all 4 switch boards.
- Page 5 Please note that the board are installed upside down in reverse order (counting from right to left) to make sure we don’t need a too long interconnection cable between the main board and the first switch board. That also means the key assignment is reversed, switch 1 triggers the highest note and switch 49 triggers the lowest note.
- Page 6 Use the interconnect wires to connect the main board and the 4 switch boards. This is how we routed the interconnection cable from the main board to switch board 1, see also the picture of the main board placement. Make sure the cable doesn’t get squished when closing the synthesizer.
- Page 7 Installing the key contacts Cut the ribbon cables to length and strip the wires. Switch board 1: The first wire of the 20 wire ribbon cable gets soldered to the common contact. Wire 2 gets cut. Wires 3-18 get soldered to the first 16 key contacts. Be careful not to desolder the internal wires.

Page 8: Power Connection
Power connection You need to extend the included power wire assembly. Solder the yellow cable of the assembly to the yellow cables on board LC82810, the black one to the black one, and the red one to the brown one. Make sure there are no shorts! - Page 9 Installing the midi socket The midi socket can be installed on the back of the machine like we did. Use the provided drill guide to center punch the locations of the 3 holes. The two small holes need to be about 3.2mmm to 3.5mm in diameter, the large hole 15mm.
- Page 10 Wires are not included in the kit. Press the learn button and while it is pressed send a midi note on any midi channel. organDonor will use this midi channel from now. These settings are saved.
