Re: [disklavier] Fault with new DKV Mark IV

2013-05-06 by CarolRPT

There are several different piano tones included on that sound card.  The headphone jack used to have its own amplifier and a sampled version of the Yamaha CFIII concert grand piano.  So check the settings and see what tone is being played and that the volume is set to your liking.  It also depends on the data in the music files.  Are you having this problem playing Yamaha files?

In none of the instances when the keyboard drop-out fault has occurred, has the laptop been connected to the DKV.  I have agreed with Yamaha that we will wait and see if it happens again.

The tonal quality (in my opinion) has also suffered.  Before this occurrence, the digital piano in quiet mode was a very good approximation of the acoustic piano.  Now it sounds like a $1,000 cheapie. The tone is a flat tone with no harmonics or overtones that you can hear from the acoustic piano.  This is somewhat subjective - when I first got the DKV I was amazed at how good the digital piano sounded.  Now I am embarrassed to show it to anyone.
