RE: [disklavier] Fault with new DKV Mark IV

2013-05-07 by Geoff Ward

The piano selected is the grand piano.  The settings have all been checked
by a Yamaha rep.  The tonal problem is noticeable in playing any file or
playing from the keyboard in quiet mode.  

The 8th keyboard lock-up happened tonight.  In fact, the whole thing was
frozen in quiet mode and no sound could be obtained at all.  It needed a
reboot.

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?

the digital piano in quiet mode is a close tonal approximation of the
acoustic piano - or is there a big difference - like chalk and cheese? None
of the dealers where I live have a Mark IV on display.

digital piano suddenly stopped playing. The only way to get it working again
was to power off and on again. A string of I/O errors were reported on the
screen of the PRC100.

fault, claiming that because I have connected a laptop to the USB port and
played some MIDI files on several occasions, that this has somehow upset the
settings of the DKV. 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.

immediately noticed that the digital piano had lost its "guts" -playing
loudly does not produce near the volume that it used to. 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.

opinion) before the fault occurred. He says it sounds ok. Hence, my question
above.
