Kawai Synthesizers

i've got a very clean new-looking K1rII which unfortunately has

a problem - the sounds/waves don't play back properly, they

seem to randomly cross modulate with others at different points

on the keyboard. the sound is nearly clean sometimes but then

you hit a key and it's obviously wrong. have reloaded factory

sysex, and the battery still measures 3.16v or something similar.

(did the sysex with 2way connection too, in case)

so i put it away wondering what to do about it, not able to get more

info - other than that the proprietary chip can go bad (which one?)

and nothing can be done about it. ...

but i had another listen the other day, and tried muting operators,

and found that a waveform still sounds if you turn off the operator,

and that the envelopes have no effect. this is where the fault seems

to be appearing; need to have another look to see if i can pinpoint

anything consistent other than that.

does this ring any bells for anyone ?! :-)

i don't think i could fix it anyway; maybe someone here is interested

in this unit - if in europe, from postage point of view, although i'll

send it anywhere, if you pay. i would like to recoup my costs though.

France.
um, it has cost me 60eu.

dunno: SQLguy did an amazing job on that thread cannibalizing ;
a K1m for the part, and changing all three chips in the end
before finding the correct one. so maybe very feasible.

i've replaced it already with a k1r with a simple stereo out.
having 4 outs would really be nice on that machine but 2 is ok
as well.
