Digital piano decay time volume dependent?

[1piano4joe]

Hi all,

Does turning the volume knob up on a digital increase the decay time?

I have a high end acoustic but a super low end Casio with 61 unweighted keys that are NOT touch sensitive. The volume knob doesn't seem to increase the decay time on this "toy".

I will be purchasing a high end digital soon and was just wondering, Joe.

Decay time varies from digital to digial, from what I've seen Casios are short all across their brand. Volume doesn't help. But I've got a Kawai digital which allows me to set between 10 levels of decay time.

There is a cutoff point in dB where you don't discern the tone any more, based on your hearing acuity.  With the volume, amplification, and speaker system punching out a higher dB to begin with, that cut off point will shift and present a longer (percieved) decay time slightly on better DP's.  Some lower quality DP's will quite abruptly cut out far short of what an acoustic piano does.  Also, with the sustain pedal engaged, an acoustic will add to the tone with all the undampened strings sympathetically vibrating along, this builds sustain time on the played note by coupling vibrations on the strings via bridge and on through to the soundboard.

Depends on the instrument. I have a Yamaha P35 and after playing through some sections of the Military Polonaise, say, the sound lives for another ten years
