I recently purchased the Roland Vh-11 and zourman conversion module to overcome some of the hihat issues on legacy 2box kit. Now I have following challenges:
1) Loud bow sound
On hihat the bow sound is more loud than the edge sound with the same stock hihat sounds that had no issues with 2box hihat. This means when i play my normal style on 4/4s: 1s and 3s stick hits more towards edge and 2s and 4s to bow. ..all songs sound like reggae as the 2s and 4s are louder (on last gig Billy Idol's Rebell Yell sounded like never before...

) . I already got good advice from Anders to purchase the Dsound manager to lower the volume of bow sound of hihat which worked to some degree, but I'd like to hear other thoughts as well.
2) very loud sound when hittin the stick "horizontally" to bow
When I hit the hihat so that bigger surface than just the tip of the stick hits the bow, the volume of the output is again very loud. This causes strange dynamics while normal playing. Anyone else noticed this and any ideas how to overcome this?
3) What's the function of the bow cooler? I tried to tweak it to overcome the issue 1 with some variation but not a full fix.
4) Have you encountered any issues on sound stability / interference, etc if not tieing HH pedal and bow/edge cables to the hihat pole?
5) What settings are you using for zourman cooler, and UNIT (and which sounds used) for gigging?

Best regards,
Juha
