Playing eve online with razer synapse installed, Macro required for keyboard binding

Using Razer DeathAdder for playing Eve online and since mouse software update to Razer Synapse 2.0 facing with binding keyboard key on mouse button issue: after pressing mouse button 4 (Ctrl binded) Ctrl isn't holding, it's On and Off shortly, like just single click on a keybord. This issue appiers only in Eve, in other games mouse binding works like a real key on a keyboard. Somebody told me to do a macro for the key to hold it longer but I don't know how? Can you please advise?
