The  K4 waves would be particularely interesting but i have

to figure out a easy way to compress these waves from 16 bit to 8bit! >>

I used to work in product development at Kawai (just after the K4 was 
introduced).  Almost all of the waves in the K4 are actually 8-bit samples.  As I 
recall, the K4 actually only had a few real 16-bit waves in its ROM.  It did have 
16-bit DAC's, though.  Those DAC's and those couple of 16-bit waves allowed 
them to call it a 16-bit machine!  A lot of those K4 single-cycle waves were 
ported over from the 8-bit Kawai K1 (you don't notice the crappy resolution on 
those so much, because of their single-cycle nature, and because they are 
full-scale amplitude continuously looped tones).

BTW, the Kawai XD-5 used the same sound engine as the K4, but had a different 
wave ROM.  Almost all of the XD-5's waves are 16-bit samples (some of the 
single-cycle waves were ported over from the K4 - the drum samples are all 16-bit 
and were done here in the USA).
