JULY 2015 Pedal Functions.

Here is an article I wrote for the Yamaha Club some while ago, but it is still relevant on most models

A couple of articles ago I explained how to use the pedals on a Clavinova to change the REGISTRATION BUTTONS while you were playing.

This month we will be looking at some of the other functions available to use on the pedals.

I am using a CVP409 this time but the procedure is much the same on all models, including most of the keyboards.




Press the PIANO RESET button to bring the Clavinova back to straight forward piano.

Press DIRECT ACCESS and then press one of the pedals. It doesn’t matter which one.

You will now be on the CONTROLLER page.

By pressing buttons A and B you will be able to see what the current function of each pedal is.   ie



LEFT           SOFT

AUX            VOLUME


SELECT CENTRE using the A and B buttons. This pedal is not used very often in normal playing so is ideal to play around with while you are experimenting.


Now use the upper and lower number 1buttons under the screen to alter the FUNCTION from SOSTENUTO  to GLIDE.

You will now find that when you press the middle pedal it will make the sound you are using glide down and then back up again.

This is not so good for the piano sound but can be very useful on things like Trombone, Hawaiian Guitar, Bass Guitar etc.

Along the bottom of the screen you will see that you can alter whether the sound glides DOWN or UP.

How far it glides, anywhere between 1 and 12 semitones, and, using buttons 4 and 5, how long it takes to get there and back.

Buttons 6-8 let you apply the function to either LEFT, RIGHT 1 or RIGHT 2.


The next FUNCTION you come across is PORTAMENTO.

Play and hold a low note on the piano using a TROMBONE  sound, press the middle pedal and now play a high note. You will hear the sound slide from one note to the other.

This can be very effective on some of the SYNTH sounds.



This works much the same as GLIDE but the sound goes from one note to the next without the glide in between.


The two following FUNCTIONS called MOD 1 and MOD 2 apply a vibrato or tremolo to the sound being used. This will vary depending on the type of sound being used.


The next FUNCTION is called S.ART and will add different sounds only to SUPER ARTICULATION voices.

These are sounds that have, S. Articulation, written above them on the VOICE page such as SAXOPHONE and CONCERT GUITAR.


The next FUNCTION called DSP VARIATION, switches the VOICE EFFECT on or off.

You will only hear any difference if there is a voice effect applied to the sound being used.

Try using DANCE ORGAN sound. The pedal will switch the “Leslie” effect from fast to slow.



This will switch the tremolo sound off and on.

Try it with the TREMOLO VIBES sound.


The next FUNCTION called HARMONY/ECHO is a lovely one.

Try using the ORGAN RHUMBA from the BALLROOM section, turn on the ACCMP and the OTS LINK button and select style Variation 4.

Make sure that the middle pedal is set to HARMONY/ECHO and press the pedal on and off

while you are playing the rhythm along with tune. Try playing Spanish Eyes.

You will hear a harmony part being added to your right hand melody as you press the pedal.


There are loads more functions that we will look at next time.


As usual, if you get stuck, give me a call on 07932 626585, or email, roger.hagarty@ntlworld.com

See you next time.
