Midi click!!!

[sub guy]

I recently purchased a Linnstrument midi keyboard to control my Model D and my Sub 37. Even though it has a lot of functionality it is just a basic midi keyboard sending universally recognized midi signals.

The problem I am having is that when using it with the Model D it is creating a clicking sound whenever I have on key pressed and then also press another (like when playing fast). My Model D has never been a clicky instrument like some synths can be. Do you have any idea why using a midi keyboard with the Model D could cause this noise artifact?

Also and this is strange but once that clicky sound showed up it now happens even when I am using the Model D's keyboard even though I am sure it was not happening before using the midi controller....

Signal chain is Linnstrument--Model D reissue-- PA. NO midi hubs just the cord.
