This Digital Keyboard does not come with a pedal unit. • You can use the PEDAL1 jack to connect an optional (SP-3, SP-20) sustain pedal. You can use the.

I would suggest cleaning the volume pedal jack as the next step.

Thre is a sustain pedal jack next to the foot switch jack. The pedals used are different. The foot switch is a latching switch, the sustain pedal is a momentary.

I would suspect the sustain pedal jack on the keyboard is either dirty or defective. Try using some contact cleaner first, and if that doesn't work replace the jack.

The Casio Privia 410r has two pedal jacks at the back. One is the sustain pedal, the other is the soft/sus jack. Please use the other jack if you want to use sustain pedal. Only 1 of the 2 jacks can be used.


However, if you have the optional sp30a pedal which plugs UNDER the piano instead, then only can you have 3 different piano pedals.

every sustain pedal got different polarity.. normally just go to global setting on your keyboard and change damper polarity setting to plus or minus (select which one work with your sustain padle).

Sorry, but the Yamaha pedal has the opposite sense (it is a normally open contact) than what is REQUIRED by Roland equipment. Roland requires a Normally Closed contact. Unfortunately, one is confused because the Roland jack for the sustain shorts itself to no sustain when you unplug a pedal. SOMETIMES one can open a pedal and with soldering iron change a wire to reverse the pedal sense IF the particular pedal has both contacts available.

1.Make sure you are plugged in to DAMPER (not FC1 or FC2) 2. Check to see if the notes STOP sustaining when you PRESS the pedal. If that is the case, first try turning off the Roland with the pedal plugged in and restarting with the pedal pressed down. 3. Press the EDIT button and scroll to Damper Polarity. See if it's set to Standard or Reverse. 4. If problem persists after all that, try holding the pedal jack into the Roland at different angles and then try the same with where the cable connects to the pedal. At that point, you can either attempt to repair the pedal or get another one.
Hope this helps, Stewart

CLOSED is typical for Roland pianos when at rest. (open to sustain).

Note that the jack PROBABLY has a grounding contact so when no pedal is used/plugged in, the jack is shorted at the piano.

Usually that indicates that the polarity of the jack for the sustain pedal has been switched or someone has substituted another pedal with the wrong polarity. Try looking in the manual to see if that is an editable parameter for people who might not be able to obtain an original pedal. You may have to initialize the keyboard which is on page viii of the manual. The jacks on the back for footswitches are on page 1 and 2. The footswitch settings are on page 9. I found the manual here:http://soundprogramming.net/manuals/Ensoniq_KT-76_KT-88_Manual.pdf I don't know if you have the single footswitch or the optional stereo footswitch. If it is the single footswitch, the default setting should work correctly if it is the original SW-2 or SW-6 pedal switches. If it is the optional SW-10, the FTswL setting should be Unused. Hope this helps.
