The Accordionist,
The XD-series can be updated with new sounds once you purchase the new Sound chip extention. This chip is very easy to install and once installed, you are now open to a new lib. of sounds that partain to you ... including accordion sounds.
Currently available is the new Contemp. package from Ketron that does include accordion voices (in stereo).
Contact your closest dealer (or Bell Douvox Corp.) for more details.
Thanks,
AJ
