Hi Joshua,

Regarding the "stuck" key: Have you checked the caps on the keyboard? 
There should be one cap per key. Sometimes these will fry and the 
corresponding note will sound continuously. I haven't experienced that 
problem on my DS-2, but it's a common ailment with Arp Omnis, so perhaps 
it's a factor here too. Incidentally, I recall a recent posting from 
someone with this same problem. It was probably in the past four to six 
weeks. Check the archive and see what you can find.

As for your problems getting poly mode to work: Have you checked to make 
sure all your IC cards are firmly seated into their slots, and to ensure 
no other internal connections have come loose? I ask because when I 
received my DS-2, the monosynth wasn't working. I opened the synth and 
found a card had slipped from its slot. I popped it back in and all was 
well.

Let me know if you find any answers to your problems, Joshua. And good luck.

Chris
