Well the strange noise following the sounds is resolved. Still dealing with the programming issues of the atomahawk features:
- 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
