ProRecord and ProScan Installation Procedure
for Grand Pianos
With Troubleshooting Guide
March 13, 2014
Installation Procedure:
1. Disassemble the piano
oRemove the action from the piano.
oRemove the stack and keys from the keyframe.
oPlace the key upside down on a bench supported by two long pieces of wood to level the bottom
of the keys.
2. Placing reflective tape on keys 1 and 88
NOTE: The following procedure is the same whether a grand or vertical.
oLocate the reflective tape and paper jig in the kit.
oStarting with key 1 and 88, place the template on the front/bottom of the key and attach the
reflective tape. Do this on both keys.(See Ill. 1)
Note: Because keys 1 & 88 are wider than other white keys, the reflective tape is place on one side
of the key to line up with the optical sensor. (See Ill. 1 and the template)

3. Marking all keys for reflective tape position
oPlace the keys up side down on two pieces of wood to level out keys. (See Ill. 2)
oPlace a straight edge across the end of all keys to simulate how the keys will be in the piano.
(See Ill. 3)
oPlace the ruler across the bottom of the keys, at the front of the reflective tape, and draw a line
across all keys. (See Ill. 4)
oNow place the reflective tape on all keys at the line just established.

3. Install the sensor strip in the action
oPlace the sensor strip on the keyframe near the front rail.
oPlace black keys at each mounting location. (See Ill. 5)
oLocate the key spacer in the kit. (It is a “U” shaped channel aluminum.)
oPlace the key spacer over the sensor of a sharp note.
oDepress the key and note if there is any clearance between the bottom of the key and the spacer.
(see Ill. 6)
oIf there is a space between the key and spacing tool, then use front rail punchings to bring the rail
up so there is no gap and the tool can slide out without resistance.
oDo this to all mounting locations. (See Ill. 5)
oIf the key is being held up by the spacer tool then the keyframe must be cut to lower the sensor
strip the required amount. If this is necessary, go to the section – “Cutting Keyframe”.
NOTE: The spacer should just be able to slide out when the key is at full
depression. This will provide the proper clearance for the sensor strip.
Ill. 5 – Setting sensor strip height Ill. 6 – Setting height with gage
oSecure the sensor strip to the keyframe with the screws provided. It may be necessary to drill
some additional mounting holes in the sensor strip to line up to the keyframe slates. (See Ill. 7)

Ill. 7 – Additional holes drilled to secure strip
oInstall the keys checking the alignment of the reflective tape to the optical
sensors.
4. Cutting Keyframe for Sensor strip
oCalculate how much wood needs to be removed for the optical sensor strip.
oPianoDisc recommends using a “Drill Press Planer” seen in illustration 8. There are other
methods to remove wood but this is easy and precise.
oHere is a link to Wood Workers Supply where it can be purchased.

5. Pedal Sensor Installation
The pedal sensors are optical also and sense all three pedals. (See Ill. 9, 10, and 11)
oLocate the pedal sensors in the kit.

oFind the best location for the sensors on each pedal that is out of sight and best place for the least
amount of damage.
oMount each sensor with 2 screws.
oPlace a piece of reflective tape under each sensor.
oAdjust the sensor to so the spacer tab just touches the lever.
oNote that the pedal sensors need to be place so the lever moves away from the sensor.
oNote that Ill. 9 shows a soft shift sensor that was mounted inside the action cavity. This was
done because there was no room to mount on the underside of the keybed.
oTie up and route the cables to the control unit.

7. Mounting the Control Unit
NOTE: The control unit can be mounted on either side of the piano but the left side is
recommended as that is the only side where the grand pedal plug has access.
oLocate the control box mounting screws in the kit assy. bag.
oPlace the control unit at the selected location slightly recessed from the edge of the keybed.
oMount the control box to the keybed.
oIf a PianoDisc player system is installed, use the PianoDisc / ProRecord cable connected
between the TFT Record port of the PianoDisc CPU unit and the EXT port of the ProRecord
unit. The EXT port is located on the right side of the ProRecord control unit (see right side
drawing on the next page).
oIf a PianoDisc is NOT installed, use the 9VAC adapter on the back of the control unit (see rear
drawing below).
oSecure all wires with the ties and clamps supplied in the assy. bag.

8. Initial Set-up
NOTE: If the piano has only 2 pedals, disconnect the cable that is connected to the
“Sostenuto” pedal sensors. Do this before powering up the control box.
oPower On - Turn the power on.
oA chime will be heard and the “PLAY” and “REC” lamps will flash alternately
indicating that the system is in “Initial Setup Mode”
oPlay each note of the keyboard with equal force, making sure each key goes to full
depth. When each note is released, the note will sound slightly delayed indicating
that each key was calibrated.
oPress each pedal with equal force and full depth. A chime will sound after eah pedal
is pressed indicating that the pedal was calibrated. The chime for each pedal will
sound at a different pitch.
oPush the “PLAY” button. If the calibration of all keys and pedals was successful, a
chime will be heard and the “PLAY” and “REC” lamps will stop flashing.
Notes
o If the system is powered off before the “PLAY” button is pressed, the calibration procedure will not
be completed and must be done again.
o It may be helpful to pause a moment between each note to ensure that the note calibrates
properly.
o If any key or pedal did not calibrate properly, setup cannot be completed until the keys and/or
pedals have been calibrated. The system will play the MIDI note of the keys or pedals that need to
be calibrated. Play the keys or pedals again and then push “PLAY”. If the problem is with one of the pedals
not calibrating, the sensor may be too close to the pedal lever. Try moving the sensor further away from the
pedal lever.
9. Sensor Re-calibration
The sensitivity of the keyboard and pedal sensors can change with time and/or temperature. Periodic
adjustments are required to keep your system operating at its optimum performance.
oTo Re-Calibrate the system, press “PLAY” and “REC” while turning the power on.
oA chime will be heard and the “PLAY’ and “REC” lamps will flash alternately indicating that the system
is in set-up mode.
oPress any keys or pedals that need to be re-calibrated. It may not be necessary to play every key
and pedal. Only those that need calibration.
oPress the “PLAY” button. If calibration was successful, a chime will be heard and the “PLAY” and
“REC” lamps will stop flashing.

10. Devices to Record to – Wiring Diagrams
oUse the following wiring diagram for iDevices with PianoDisc.
oA lightning to 30 pin adapter may be needed depending on the “i” device version.
