There's unnatural muting of sounds when closing the hi-hats slowly. It's a bit noticeable at speed too though. Essentially any sustain is stopped dead, very electronic. Is there anything that can be done about it?
It's by design I'm afraid. The pedal splash accounts for both the chick and splash by cutting the splash sample short. You can replace the pedal splash with pedal chick articulations from a VST and extend the sample length by increasing the hold, but its not really a solution as it affects every zone.
The artificial muting is less artificial on dry hihats, but there really isn't a perfect solution unless they add a chick zone or allow a natural decay for zone 9.
Shame, it would be better if it played the chick sound regardless of velocity rather than let the sample stop dead. I've emailed 2box as a bug report/feature request since it does seem a rather nasty side effect of coping with the splash.
