Welcome
Please read through these installation instructions prior to attempting the installation. Taking the time to
understand this product before starting and exercising care during the installation will promote immediate
success.
On which keyboard instruments can I install a PNOscan II sensor strip?
The PNOscan II was designed in
such a manner that it can be installed in virtually any piano. For most acoustic pianos the installation
process is straightforward. Occasionally with pianos, and more frequently with organs and other keyboards,
a successful installation will require some creativity on the installer's part.
Acoustic pianos:
There must be enough room between the bottom of the key and the highest portion of
the key frame so that the key does not hit the sensor housing. Fortunately, for most acoustic pianos this is
not a problem. More than likely you will have to shim the sensor strip higher.
Please unpack your kit and report any damage or missing parts immediately. See page 6 for the complete
parts list.
Brief Description
Key Scan Assembly:
The key scan assembly consists of a series of optical sensors, one for each key. Each
optical sensor has one small plastic "tower." The tower transmits and receives a beam of infrared light .
As the key moves it gradually changes the intensity of the amount of light detected. The assembly is
mounted to the key frame, positioned so that the bottom of each key reliably reflects the light. Since it
is optical, absolutely nothing effects the touch of the key. The travel of the key is not restricted by the
assembly - each key still has the same range of motion it had before. The Key Scan Assembly consists of
four printed circuit boards inserted in a metal track.
Pedal Sensors:
Although PNOscan
II
was designed to detect the movement of all three pedals, only two
Pedal Sensors are supplied with the PNOscan
II
system. The smaller “Sustain” Pedal Board is used to detect
motion of damper tray on a Grand, or the Pedal Lever on an Upright, when the sustain pedal is depressed.
The larger “Soft” Pedal Board” detects movement of the key frame on a Grand, or the Hammer Rail on an
Upright, when the soft shift pedal is depressed.
TUSB Interface:
The TUSB Interface is the control center for the system. Used to setup, or calibrate, the
sensors after the installation. Lights indicate activity and buttons are used to change operating modes. The
interface transmits MIDI data, allowing the user to connect to external synthesizers and sequencers.
Will you be connecting this PNOscan
II
record system to a QRS Petine controller?
If so, you will need a MIDI Adapter Cable, #99140, and set the jumper on the Petine
!
