Can somebody please help me with telling me which file type I should import to my Ketron MS100 to load it as a user voice?

David Ryu,
The Ketron MS100 can load up to 4 propriotry sound files (of type .SND) developed by Ketron at any given time. The sound grooves (.GRV) are loaded when patterns associated with particular loops are loaded too.
Hope this helps,
Thanks,
AJ

Thanks, AJ. I was hoping I could create sounds for it, but as I checked, Cool Edit exported *.snd files it recognizes as corrupted. Is there still a way to obtain the Ketron Discs for MS series?
Cheers
