Dorico has been running incredibly laggy for the last couple of days, even moving the mouse around takes ages for Dorico to respond on any window (properties, Write, Expression Maps, etc.). I kept looking at the Computer Monitor, CPU was barely at 8%, RAM at 6%, with or without VSTs loaded. I even reinstalled the whole program and then it occurred to me… What if something is sending too many signals to Dorico? So I loaded an instance of Kontakt and used the Factory Mulitscript “MIDI Monitor” and there it was! MIDI CC2 was continuously being sent. My MIDI Keyboard has an Expression Pedal which is configured to use CC2, as soon as I unplugged it from the keyboard Dorico went back to being smooth as silk!
I have never had this problem with any other program, I tried it on Cubase and other unmentionable notation programs and despite all of them reporting a continuous CC2 none of them were affected in terms of performance. I thought this would be worth while reporting and seeing if the Devs can come up with a solution… Other than unplugging the cable that is !
