Reply to midifighter classic - static sound when using beatmasher buttons

Recently, my midifighter has been giving a staticy sound when using the beatmasher buttons (+ gater but to a lesser extent). It either happens when a button is pressed or released. It doesnt happen all the time but enough to be a problem.

I can use same effect parameters on x1 with no static.

Any ideas on possible causes? I've tried to adjust my latency and have tried a different usb cable but no luck. Would a midi conflict be a possible cause? Doesnt seem like pressing one of the buttons should affect sound quality but Im at a loss..
