Yes, and it is always the "A" key - why is that???

Usually, contact strips come in sections. Two or three are needed for the entire range. The reason why specific notes tend to go bad is that they are usually at the END of one of the strips, so there is a much larger area for moisture and dirt to be able to creep in and mess with the closest contact.

The problem seems to be there since the beggining...

Yes, this is a note in the middle.

It's rare, so I don't care too much, but the last time it was when the bride enters ...

Yamaha contact strips, both for the PSR and Tyros series, come in octave strips. They're about $20 and fairly easy to install. You'll find complete instructions at the PSR Tutorial site.

What is strange, is that it seems to be related to the sustain pedal.

Dan,

It really has nothing to do with the sustain pedal, but when you hit the pedal it exacerbates the problem dramatically.
