Buy sustain pedal made for CASIO or switable model.
Pedal for Yamaha or Roland will work in reverse on a Casio.
If you cannot return for exchange, then open up and solder a different type of micro switch.

SOURCE: Casio 1600 sustain pedal problem

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.
Good luck!
Paul

SOURCE: bought a sustain foot pedal and it works the opposite

Yep!!! Happens all the time and only a few synths have the option of selecting the operating mode.

NOW if you can open the pedal, USUALLY the switch has both the Normally Open and Normally Closed functions that a single wire can be moved to reverse the operation.

USUALLY you will need a soldering iron to make the change.

Make sure you are plugging it into the place for the sustain pedal. If you happen to plug it into the audio out it may kill the sound.

If you caan get to the pivot point, try putting a little CRC226 on the pivot bearing and mechanism. You can get this in the electrical dept of Home Depot. About $2.70 for a can with spout. This is plastic safe. Use sparingly. Lube movement points.

Looking for a sustaining pedal for the Casio ctk 401 keyboard. What models will be compatible?


They are all compatible. Make sure the port on the keyboard is the same size as the plug on the pedal, usually a phono plug. Also make sure it is a sustain pedal and not an "on off " switch.

My son has started learning piano using the CTK 651. The music teacher needs a metronome function in this keyboard. Is there a option for this here? How do i get to that.


Most of these keyboards have such a function... the manual doesn't show any... however one could select drum set 5 and use the claves setting for a rhythm and control the rate with the tempo. This might be too complicated and it might be simpler to get a small metronome... some are very inexpensive.

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

Casio CTK-651 keyboard wont switch on


An internal fuse is UNLIKELY.

More likely is either a bad connection/connector at power input or a bad or intermittent power switch.

Is a sustain foot pedal similar to a tattoo machine pedal?


The sustain pedals have only two wires. Usually they terminate in a 1/4 inch mono plug.

yamaha USUALLY sustains when switch is closed. Roland usually sustains on a switch between the wires when the switch is open.

NO POWER should be supplied BY the sustain pedal... it is ONLY a switch.

Roland DP-2 pedal not functioning correctly.


There are two types of damper pedal switches, on that is closed until you press it, and one that closes when your press it. It sounds like your Casio is expecting one type and your Roland pedal is the other type. A quick way to test this is to plug a guitar cable into the Casio pedal input and see if the keyboard sustains. If it does, then your Casio requires an "normally closed" switch.

Some pedals have a small switch near the cord or even on the bottom of the pedal that will reverse the switching operation (BOSS pedals, a division of Roland, have this feature). If you can find that, then change the switch position and you should be OK.

If not, and you feel like digging into your pedal, you could take the bottom off of the pedal and check out the switch itself. Many pedals use a switch that can be used either way. The clue will be on the switch itself. If there is an extra tab on the switch that is unused, then switch the wire that is furthest away from that tab to that tab. This will probably involve soldering, but it is nearly impossible to damage anything.
If moving the wire that is furthest away does not do anything, then try putting that wire back and switching the other one.

If your pedal does NOT have an extra tab, you're SOL, unless you want to buy a replacement switch (unsure of make). If this is the case, you are probably better off getting a different damper pedal - preferably one that is marketed as "universal"
