Slow interface/Mac OS 10.14.6

  • Hi , I love the sound/flexibility of bias amp/fx (DEMO 22.2.10)but the interface is frustratingly slow ( stand alone/plug in)Like just changing knob value/selecting amp. If I can resolve this I will happily purchase..The FX 2 plug in is particularly slow almost unusable within Logic X.I do not have any draw /display issues with other plug ins/stand alone's ie.Amplitude /Waves/Kontakt etc.Does the app have to connect to the tone server every time I select an amp/pedal? Is there a known problem/fix for Mac OS users.Please advise. Many thanks
