As above, how long is it? I've seen the newer PX series and its double the length of my CDP, but have no info on the Yam.

Thanks

I don't see anything in the manual defining a specific value.
Now I went to start answering about the different styles and
the knob on the value, but that's for reverb. So I guess you're
talking about the pedal-induced effect. Which I hardly ever
play with (so far). Do you measure something like this by
just counting seconds a note will hold when holding the sustain
pedal all the way down?

How long a note sustains will be the same with or without a sustain pedal, you can just hold the key down with your finger. However, the decay time will vary depending on which note you strike (a low note sustains longer than a high note), and, I believe, how hard you strike it.

Hmm I wasn't very clear....

Anyway on a video of the PX350 some guy had the 330 and the 350 side by side.

He played a fairly wide chord on the 330 and then the 350 and the 350 sustained almost twice as long as the 330.

I've not seen a similar comparison with the P95 and the P105.

I'm not sure what they would report is really the right number. The time it takes for a sample to run completely out to silence is irrelevant most of the time because no one holds notes that long. What matters is how long it takes for most of the sound to decay, and this is what people complain about when they say inexpensive digitals have short decay. The manufacturers modify the samples so most of the sound decays quickly. This hides a multitude of sins the samples manifest--looping, etc.
