Hi,
I think the versionb.128s sounds better . Not perfect, but nicer than the first snapshot.
Hervé
thank you for your help
It is another test version
This version works in the following way: if noise value of AY register 6 is 01 then it plays 30kHz noise on enterprise noise channel, if AY reg 6>01 then stops channel 3 and plays polynomial distortion with value AY reg 6 x 4 on it (it is similar to sound of noise channel), only channel 0 and 1 plays noise with >01 value, and if noise value <=1 then channel 3 is restored.
Is this version good, or I should involve noise channel for all noise values?
