I am not an expert, and I am using EZD3 as a plugin in Reason12. The hihat controller doe not seem to work correctly as a plugin (it responds to open-close as a pedal, but as soon as I hit with the sticks the sound is always “open”, if it makes sense). I used a couple of different expansion packs as well to no avail.
However, it works really nicely as a standalone with my TD-50x (the software is matched to the drum module). I suspect there is something really trivial I should do to get it to work properly with Reason12.. would you mind to direct me to a post in the forum discussing this or perhaps give me some suggestion?
