Korg Poly800/EX800 Users

HAHA! For those of you who already have an AtomaHawk and HAWK-800, the upgrade cost is <drum roll> ZERO. And I will take any currency!

The moog slayer under AtomaHawk control did not suffer from this problem. So Moog Slayer is AOK.

============ ===

reminds me of the fact that most "log taper" pots are actually two linear 
regions forming a "bent knee" shape. will this optimization also apply to 
the moog-slayer, under atomahawk control?

haha... (TV voice:) "how much would you pay for this extra feature? $100? 
$200? $300? mike, please tell the existing hawk-800 users how much this 
upgrade will cost... drum roll please..."
