Disklavier

I also have a software background (and some hardware experience) and 
took a look at the MarkIV software.

The MarkIV doesn't run RedHat, its an embedded distribution based on 
Redhat (as are many distros) that runs on a non-x86 cpu. Mounting the 
disk is likely easy, but not very useful. You can see quite a lot of 
stuff on the MarkIV install CDs, but I don't think there is anything 
useful there for the hobbyist hoping to make a PC based controller - its 
all for a different CPU, and all of the useful software is proprietary 
Yamaha software and will likely have licensing restriction. There are 
some playable media files there, but nothing interesting.

I'm more than a little disappointed at Yamaha for not producing a 
replacement controller offering the MarkIV features for owners of older 
pianos. Dealers used the upgradability of the DKV as a sales argument 
when I bought my MarkIIXG upright as end of line. Several dealers told 
me, independently, that Yamaha would produce revised control units for 
older pianos as new features were introduced. One even showed me the 
DCD1 and DSR1 on a wagon grand demonstrating Mk3 capabilities on one of 
the first generation of instruments. This appears to have ceased, and 
given that Yamaha don't produce a MarkIV upright, and as I don't have 
room for a grand (like many people in Europe) I'm stuck with a control 
unit with almost embarassing synth sounds (the MarkIII didn't sound much 
better either).

(cue loads of people telling me that the MarkIV is far more than just an 
upgrade to the control unit... WHOOOSH)

Best bet is to produce a home grown solution I think, for owners of all 
player pianos and digital pianos. Probably a big market for 
cross-platform media too.
