Since I am still looking for a quick way to switch kits without fiddling with the touchpad of my notebook, I figured that I should be able to send program change messages from my drum module. I read in a forum that EZ Drummer 2 was able to interpret these messages, but could not find any documentation neither for my Superior Drummer 3 nor for EZ Drummer 2.
Since there seen to be no options for this anywhere in SD3 and since SD3 is not responding to these messages at all (except for bank select CC0 and CC32 showing up in the eDrum mappings menu), I assume that this is not implemented in SD3.
Hence: Feature request 🙂
