Need help with an Atomahawk problem

2015-01-01 by basecamp_88@...

I'm having a problem with the Atomahawk install that I just can't nail.

Here's what I've identified:


  • Moog slayer seems to be stuck in an on state (P2 58 - 1)
  • Changing the value of P2 58 does not change the state of moog slayer
  • Moog slayer resonance can be changed with P2 51
  • With P2 68 set to 1 or 2, P2 61 will distort the notes
  • Unable to determine if other FM800 control works
  • Hard to tell for sure, but 12/24db filter appears to be working
  • There is a "noise" with every note press that follows the note sustain -- here is a demo of the noise: Atomahawk Problem
  • Removing the Atomahawk, keyboard functions properly

Here is how the Atomahwak is wired up:

Pin Poly800

2 R23(low)
3 R21(high)
4 R21(low)
5 IC5 - 7
6 IC4 - 7
7 C103(high)
8 IC1 - 5
9 IC1 - 6
10 IC4 - 4

Boot 1.99
Firmware 2.59a

Does anyone have any insight, this is driving me crazy!
