While restoring this CS50 I thought, that a mono-unisono mode would be very helpful for tuning. So I am looking for a description of that modification (especially for a CS50). I've searched the groups archive for it, but did not find any details about it. I only found it mentioned as taken for known.
Are there any detailed explanations somewhere?
I tried to understand the principle of the KAS board, but I don't find any signal that resets the voice counter. I also don't find any significant difference between the KAS board of a CS50 and a CS60 (at least in this aspect).
