Electric piano Sounds like Clavinet D6
PANEL
Range: On/Off for 4 switches
NRPN MSB=0, NRPN LSB=4 
Data Entry MSB Range: 00...15 
Allows you to set the switches of the side control panel and so the sound characteristics.
The first four switches allow you to apply different filters useful to "colour" the sound, like this:
-
Brilliant: very brilliant hi-pass filter.
-
Treble: band-pass filter regulated on the high frequencies.
-
Medium: band-pass filter regulated on the mid frequencies.
-
Soft: low-pass filter to obtain o very loud sound.
Range: On/Off for 4 switches
NRPN MSB=0, NRPN LSB=5 
Data Entry MSB Range: 00...2 
Last two switches control the combination of the two available pickups in this way:
-
C+A: "Lower" pickup, warm sound.
-
B+C: "Upper" pickup, bright incisive sound.
-
B+D: both pickups, very full sound.
-
A+D: both pickups on, out of phase; the fundamental cancels somewhat and you're left with a pretty sharp sound.
SLIDING MUTE LEVEL
Range: 0...50
NRPN MSB=0, NRPN LSB=6 
Data Entry MSB Range: 0...50 
Sets the position of the sliding damper, in order to control the sound decay time.
TANGENT
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=0 
Data Entry MSB Range: 14...64...114 
Determines the sound loudness and timbre.
Underneath each key of the piano keyboard there is a rubber tip, called a tangent. When a key is pressed, the tangent
strikes the corresponding and traps it against a metal stud for the duration of the note, splitting the string into a
speaking and a nonspeaking part. Moving the slider to the left you can change the characteristic and size of the
Tangent
and thus its influence on sound loudness and timbre.
With negative values you can get a duller sound, while positive values give you brighter sounds.
DAMPING YARN
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=1 
Data Entry MSB Range: 14...64...114 
Allows you to change the sound release time.
When a key is pressed, the tangent strikes the corresponding string and traps it against a metal stud for the duration of
the note, splitting the string into a speaking and a nonspeaking part. The nonspeaking part is bent by a damping yarn
that stops its oscillation. When the key is released the string parts unite allowing the oscillating part of the string to be
damped by the yarn. By changing the DAMPING YARN parameter you can change the amount of yarn and thus the
sound release time.
The effect of the DAMPING YARN parameter can be better heard on bass notes. Positives values correspond to the
increase of the yarn and thus decrease the release time, while negatives values correspond to the decrease of the
yarn and thus increase the release time.
PICKUP POSITION
Range: -50...0...+50
NRPN MSB=0, NRPN LSB=2 
Data Entry MSB Range: 14...64...114 
Allows you to change the character of the sound.
Guitarists well know the pickup position affects the guitar timbre. With the PICKUP POSITION parameter you can get a
similar effect by moving the pickup location in respect to the Clavy strings. When the pickup is close to the bridge
(string end) the timbre is sharper, and when it's moved towards the string centre the timbre becomes softer.
AGE
Range: 0...50
NRPN MSB=0, NRPN LSB=3 
Data Entry MSB Range: 0...50 
Allows you to change the character of the Clavy sound.
When some parts of the Clavy age, like the tangent rubber or damping yarn, they change their characteristic
influencing the attack time, release time and impact noise.
