Question about Casio Music

Casio Celviano Ap420 - Metallic G

G above middle C frequently (about half of the time) plays with a strange tone. It sounds as if the hammer has been compacted or if a tack were place on the hammer before striking the strings. Of course, there is no hammer and no strings, so... Usually more of a problem when playing the key louder. Tried a factory reset, but no help. Only the one note, too, but I like playing in G and C and D and Eb, etc.

Hello a_marechalro,

You can try to reset your instrument.
Turn off the EWI,
Press the LEVEL, FX, SETUP and TRANS buttons.
Then turn on the EWI.
This is a Factory reset.

I hope for You this is the solution.
Kind regards,
Fred Roubos.

SOURCE: My Roland Rd-500 has no sound....the factory demo

You either did not get the ribbon cable seated OR got it upside down.

If this cable is the flat ribbon with exposed solder plated points of contact, OFTEN those connectors have a latch to release by GENTLY moving tabs on eaither side in the direction of pulling the cable out. This lock MUST be moved out slightly to allow the cable to seat properly. The solder plated contacts will be FULLY into the connector when seated properly.

These cables ALSO can be inserted backwards and NO connection will be made.

SOURCE: HI there, I Have a casio cz1 synthesizer, great

Hi,
I had a similar thing happen.
Definitely change the internal battery and initialize back to factory settings. Just hold down the red initialize button (top right hand corner) while you turn it on. It will then ask on the LCD - hit "yes".
I also had to change the battery in my external cartridge (if you have one).
There are some great (free & pay for) sound patches on the web for the CZ1 (way better than the presets) you can load them in via midi sysex.

SOURCE: Brand new AKAI EWI 4000S was playing great for 30

This sounds like a power supply issue... Since the unit is new, make use of the warranty for repair or replacement.

Yamaha DGX 220 All E and Bb keys above middle C will not play. All others OK


Just a shot in the dark but a lot of keyboards allow for splitting the keyboard in half or even in quarters to assign multiple sounds... have you tried a total reset? Or explore the manual for setting up a split keyboard. Might help.

Tone knob and switch info


the switch, has three positions. Typically forward or up will be your neck (or rythm) pick ups, only and will work with one volume knob(usually top right as your looking at guitar), and one tone knob ( top left as your looking at the guitar). when the switch is in the far right or all the way down position, that will be the saddle (or lead) pick-ups. And that works with only one volume knob(bottom right as your looking at the guitar) and the corresponding tone knob. when the switch is in the middle position, botjh volume knobs work and both tone knobs work. You've gotta kinda play around with them to find whatever sound yopur looking for. and tone knobs are very subtle in their changes. good luck

Hi i have problems with my speakers on my pa 800 ,when i just play tones its clear but when i play the rhytms doesn't play right is not clear


Read your user manual about keyboard split. OFTEN the rhythms use the keys below F sharp for the chording of rhythm. When in this mode, you should restrict your melody to notes above F sharp that is to the left of middle C. If you play melody below this it will confuse the rhythm chording. You can likely change the split point of the keyboard, however, the F sharp split is the standard and I would suggest staying with it.

My boss DD-3 makes a strange tapping sound on all modes. tapping sound gets more frequent when i turn the delay time pot to the right. its like a little tap sound getting into the circuit with the guitar...


Check your power source or battery. The sound is probably due to the internal processor recycling due to watchdog timer. If power is OK, then service will be necessary to repair the problem.

The problem I have with my music man bongo bass 4 strings,,, is that the string 4 at fret 5 sounds very strange as making waves, but it sounds good with the other tones, on the other strings when I play...


Check first it is not hitting or touching the next few frets, in case they are high. Or maybe the 5th fret is low. You could raise the action and/or adjust the neck relief to test this.

If it is not a fret problem, it may be a real dead spot on your bass. If so, it would be regardless of the pickup used and could be heard acoustically if you could hear notes that low easily. Most guitars have notes on the fretboard somwhere that are a little dead. It is due to destructive interference and there is not much that can be done. To happen at the 5th fret is unusual though. Make sure the string is wound properly around the head, and that nothing is loose and actually moving/buzzing when you play the note.
Other causes can be a loose fret, loose bridge parts or a loose neck joint.

The keys in the middle range of my Yamaha electronic piano P-200 seem to be stuck and are very difficult to play - takes a lot of strength to get any sound. Could humidity be a problem? Could piano...


Although the keys have a weighted feel, this is not because of a system involving connection t hammers as in an acoustic piano. This is done mechanically, however, which would indicate a need for cleaning. If you have an authorized Yamaha service center in you area they would need to do the cleaning.

Neck and Middle pickups make little sound even with volume at max


Hi There!!

I am a gitarist myself too and firstly let me tell you u have purchased an excellent guitar to begin with!! 
Now about the Neck\blues pickup.....If you say there is little sound this can be because of:-
1)Faulty bridge adjustment
2)There can be a problem also because of  the neck of the guitar being a bit bent in or around the place where u have the pick-ups though the chances of that are rare.

If there is no sound then please contact your dealer to change the piece....
Have a great time playing

Hoping this helped.Any help regarding the above steps , feel free to ask them.
See ya.

Do you cover the keyboard when not in use as small particles of dust can make their way in between the keys?

You can try blowing any obstruction out with a can of compressed air, may solve your problem.

As I'm not familiar with this Model, does the keyboard have 'touch response' on board? If so there will probably be a 'Contact' strip made out of tubular rubber under the keys and this can sometimes 'burst' especially on a certain key that is played most of the time. For example if you play mostly in the key of 'G' or keys that use that note....

Hope you find this helpful......

Problem with volume dials in an electric guitar.


If you can't clean the pots or if you just want to try replacing them, try using
500k pots again, in case one or both of the pots is worn or dirty or
defective. If that doesn't work, and cleaning or replacing the
switches doesn't work, then the problem is probably elsewhere.
You could put a 500k resistor (with a sufficiently-high power rating of at least half the power rating (Watts) of the pot) in parallel with the pot, or, to cover all bases, put a 500k resistor from each of the two outer lugs of the pot to the middle lug. That should change it into the equivalent of a 250k pot. You could even just temporarily clip the resistors on, with alligator-clip leads, if you're very careful, just to test it.

Good luck,

The dude.
