VST plugin stops sounding in Cubase Artist 10

I use Cubase Artist 10.
I want to use a third party plugin I purchased (UJAM’s ‘Virtual Drummer’ Bundle, suggested by Steinberg). After installation, I successfully choose it in Cubase and it loads. Everything functions as described and expected to play it alone. Only, a problem starts when I import a MIDI drum file and send it to sound from the ‘Virtual Drummer’. The first time it plays. When I replay it , there’s NO SOUND anymore. And no sound even if I play the pads in the ‘Virtual Drummer’ window. What could be the reason for that problem and how to overcome?


Hi and welcome,

Could you try to increase Audio Device Buffer Size?
