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. We already connect these jumpers for you.
In the case of the Roland RS-09 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 case. Then stick
double-sided tape on top of the insulation tape and place the boards on
the bottom of the case under the keyboard like shown in the picture.
Plug in the interconnection cables and the switch board cables.
Now solder the switch board wires to the key contacts:

Take care that you don’t accidentally desolder the internal wires.
Switch board 1:
Wires 1 – 16 get soldered to key contacts 1 – 16.
Switch board 2:
Wires 1 – 16 get soldered to key contacts 17 – 32.
Switch board 3:
Wire 1 gets cut.
Wire 2 gets soldered to the common connection bus bar).
Wires 3 – 14 get soldered to key contacts 33 – 44.
Wires 15 – 18 are not used.
Wires 19 and 20 get cut.

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 guide the wires under the keyboard to the power supply board.
Then solder the wires to the power supply board.
The yellow wire gets soldered to the -14V terminal, the black wire to the
ground GND) terminal and the red wire to the +14V terminal.

Installing the midi socket
The midi socket can be installed on the back of the machine, we
recommend the space right next to the external input. As the space is
very tight you could also use a 3,5mm stereo jack instead of the
standard 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. Here we typically use a stepping drill.
Installing the learn button
The optional learn button can be used to set midi channel. It needs to be
connected to the IO “2” and “G” pin on the main board. The back of the
main board has labels on it). 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 on. These
settings are saved.
Configuration
We already flashed the corresponding configuration file to Organ Donor.
There is, however, a software configuration tool available, in case you
want to play around with settings and key assignments.
You`ll find the configurator here:

This is a browser application, it works with Chrome and Safari right
away, Firefox needs to be configured for web MIDI.
The configurator allows you to upload your settings directly from your
browser to OrganDonor, safe and load settings and export settings as
SysEx files for uploading to Organ Donor via another SysEx tool.
