What driver do you want to install?

Hi
I'm not sure I completely understand your problem but......it sounds like you might be in "Fingered On Bass" mode. This means if you play a chord like F using the notes FAC- if you play them in 2nd inversion (so the order is CFA) the psr-1000 will make the note "C" the bass note. In this mode if you played ACF then "A" would be in the bass part. Change to "Fingered Chord"-this will enable you to play any chord with the tonic (the name of the chord) F whether you play FAC, ACF or CFA in the bass part. I don't have access to a psr-1000 but often with Yamaha instruments this can be changed by pressing and holding the "Auto Accompaniment" button. I hope this helps.

Hi, This is probably due to worn rubber contacts. The sound is switched by pressing a key which in turns press a carbon contact on the PCB under the key. In time these wear out and need to be replaced.

Firstly open up the keyboard and locate the rubber contacts, check to see if each one is seated squarely, if they are not seat straight then this can create the problem you mention.

If all are OK then you will need to replace the strip which is causing a problem.

Spares are available from many sources including :

If you have any key note problems with your yamaha psr 9000 and need It repaired contact a qualified engineer at [email protected]

Check that the power adapter is the genuine part for this keyboard. The wrong adapter would cause this problem.

That sounds like a serial number... they are long... The product ID probably isn't needed

Search Ebay for "psr 450 adapter"... They cost about $16

You have to completely remove the circuit boards. If this is the keyboard I'm thinking of then the keys are all mounted on the same part like parts on the sprue in a model airplane kit. If its a different one then you have to remove the assembly and take the spring of the key you want and at the other end when you flip it over there is a strip glued on the metal frame to secure the keys that you have to peel off for that sector.
