Now I get an anoying delay: every time I press a key it doesn't inmediately play the sound. and i get a buzz sound when i press a key too. my pc is windows 7 inspiron 1545

Ugh! the only way to fix this is to dismantle your D-20 to get to the bottom of the key bed. There are rubberized strips under the keys that have pads which make contact (hence, key contacts) in several places with the actual keys. The strips are attached with rubber nibs that snap into place on the base of the key bed. The reason for the lack of sound and/or the millisecond delay is a speck of dust that somehow made its way onto the contact for that key. If you decide to take this task on by yourself, make sure you clean the rubber strips (yeah I'd do all of them while you're in there) completely with canned air and contact cleaner in a dust free environment, and be sure to attach the rubber strips completely to make a dust-free barrier. Once you see the strips, the explanation will make sense. If this sounds overwhelming, take the board to a repair shop and their tech will fix this for you, as they see this issue all the time with velocity-sensitive keyboards. Good Luck!

Is this a synth?
Check the attack settings

I can totally relate, Tom. Good old multitrack recorders!
This may sound stupid, but you don't have like a slap back delay turned on by mistake, do you? Other than that, I'm afraid I'm not much help.

Hi J Wade. I'm Dave P. I'm not a guitar amp expert or technician but I've been using amps and effects for 35 years and there are a couple things I can suggest.

That kind of periodic noise/switch noise can be a symptom of having the polarity of the amp reversed. If your amp has a 3-position OFF/ground switch, try reversing the ground. If it doesn't, take the plug and turn it around. Just don't get near a microphone unless you're sure your amp is grounded the same as the P.A. It could fry your lips off.

Dirty switches to that too. You said the noise is in time with the delay's tap time which is set by a foot switch. If tapping that switch the first time generates a pop, the delay may have catch it and is repeating it. Turn off the amp, remove the delay foot switch and turn it back on. Still noisy? If not, give the foot switch a good cleaning.

When you turn the EFFECTS knob up, is it scratchy? Might need the potentiometer cleaned. What happens when you specifically turn the DELAY level down all the way while using the other effects? Noise still there?

That's all I've got. Hopefully, it was helpful. Don't wrack your brain over this too much. There could very well be an internal problem with your amp that will require a trip to the shop. You don't want to open it up yourself. Rock on but be safe.

Usually that is a programed feature, but you can try the support center at the manufactures website.

Check the switch to be sure the keyboard is in normal mode and not chord mode. This will cause there to be no sound unless you play a chord on those first 11 keys. Pressing play activates whatever song is loaded at the time, allowing full keyboard use.

I have an older Casio, and the same thing happens all the time, especially when I'm in a hurry and don't check where I put the switch.


Hope that helps!

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/cameron_463100ffd54b591d

The green light is NOT a tempo light and will not be in sync with applied audio. If you need a tempo indicator, turn on a click track in your computer or use a metronome.

If this is happening on all keys it sounds like your aftertouch is not set right. You may not have gotten the key assembly lined up quite right also. Check these first.

Try restoring to factory settings first by turning it on while holding down the Level,Fx,Setupand Trans keys all at the same time. Your key delay function might be out of adjustment. You also have to remember to keep at least one of your thumbs on one of the earth plates. Refer to your owners manual. Start with the factory settings and compare each page of the manual to your instrument until you familiarize yourself completely with the manual. Play the instrument for a while with factory settings until you decide where you have to make changes. Work slowly with each adjustment and the manual until you get what you want. Some adjustments will affect others. Take careful note of what the manual says about temperature and humidity changes.

You are suffering from midi latency. There is a good article about this at www.thewhippinpost.co.uk/latency.htm There is also some good advice there.
