I found that if I plug in the sustain pedal BEFORE turning the power on, it works fine. If I plug in the sustain pedal AFTER turning the power on, then it works in the opposite way. Probably just the design. So I would try playing with that before doing anything drastic.

Re: Sustain Pedal Opposite Effect
No , there is only one solution, open the pedal and fix it.
Teh sustain pedal has a circuit that can work in two ways:
Sustain from compressor: This will create sustain by using a series of compressor (device that compress the wave and cause the sound to sustain, Black Sabbath's Tony Yommy loved this effect). The compressor is built with a small IC or with a series of capacitors and oscillators.
Sustain from digital effect: This uses an IC similar to the one used by Digital Delay pedals.
In either case, if the sustain is well connected, and it keeps it cutting the sound, that means that there is an internal fault.
Check first all your cables and connection, with particular attention to the pedal input cable.Also remove batteries from pedal to reset it.
If the pedal keeps cutting the sound, then there is a blown component or a broken solder joint inside, it must be opened , tested and fixed.

Yep... Roland pedals are reversed, that is, normally closed contacts. Unlike some Yamaha keyboards, the Casio doesn't have an inversion function available. You have two choices to solve this: 1. Buy a pedal with the corect sense 2. Open the Roland pedal and MAYBE with a soldering iron you can move a wire to select a contact with the opposite sense.
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.
The function setting is for the PANEL sustain (Page 68 of your manual)
The other method of sustain is by footswitch or pedal option. See page 13.
If you use a footswitch, it needs to be a normally open contact type. If you plug a Roland type in, it is opposite polarity and will sustain UNLESS the pedal is pressed. Make sure nothing else is plugged in the sustain jack... headphones that are inadvertently plugged in there would sustain.
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.
What I figured out is that when i turn on the keyboard, if i hold down the pedal by accident, it will work in reverse. I dont know if this is what you mean. If it is, just dont touch the pedal when you turn it on. If it isn't, try to return the pedal. I dropped one, it had this problem, and they gave me a new one. Your cord for it might have been bent (?). Also, turn the keyboard on with the pedal already plugged in. It's not made to be plugged in while it's on. Hope this helps. - Matthew
Not if its like mine, its a completecircuit vs.incomplete circuit problems.
I had the exact same problem with my Casio keyboard and a Yamaha sustain pedal I bought.
I'm not an electrical genius, but I was able to get it to work by opening it up and doing a little modification. Of course I first just tried switching the white wire with the black one but that didn't change anything at all when I tried it. It turns out the Casio wants the circuit completed to sustain, and broken for no sustain, which is the opposite of what the Yamaha pedal does.
I opened it up and mine had three three flat metal strips let's call them Top, Middle and Bottom. The Middle and Bottom ones were joined together on the right side, and the Middle and Top ones were touching on the left side when the pedal was not pressed. These seperated when the pedal was pressed, thereby breaking the circuit because the wires were on the top plate and on the joined Middle/Bottom plate.
So to flip it I: 1. Unsoldered the Bottom wire 2. Cut apart the Bottom and Middle plates on the right. 3. Bent the Middle plate on the right to touch the Top plate instead and soldered those together. 4. Soldered the Bottom wire back on.
That's it! Once I figured it out, it took only a few minutes to fix.
