i am Dorico owner now, because after checking out Finale and Sibelius via demo, i have to say Dorico has a more modern design and better tools for playback and virtual instruments.
Unfortunately I have recognized some sudden midi velocity peaks since I have installed Dorico. Now I constantly have sudden midi velocity peaks again and again. For example I am recording or playing a soft piece within Cubase and I constantly have around 5-6 sudden midi velocity peaks in some minutes. Then you really get scared, because it is maximum velocity peaks. I also have this problem when I only play with an stand-alone virtual Instrument.
It could be that Dorico installed something that is now causing these glitches. But I don´t know what.
