Applied acoustics multiphonics , gui bug when playing pc keyboard

Applied acoustics has released a modular which sounds pretty good , problem is when using the pc keyboard while interacting with the gui (even moving the mouse cursor across the gui ) there is a enormous amount of lag and sometimes note event’s are delayed becasue of this lag
Problem only exists in renoise , tried it in the free vst host cantabile ( with pc keyboard ) and everything runs smooth .
Already contacted the developer , but like I said …it’s a renoise issue
