Hi, I’m using Cubase 9.5 Pro at Windows 10 Enterprise N 2016 LTSB.
Keyboard is Komplete A61, and audio interface is UR22 mkII.
Some VSTi sounds are changed like adding modulation after few seconds later or press shift tab to change window.
For example, I add Sonatina Orchestra from bigcat, Upright Piano from 99 sounds to instrument track, then
after 1 min, it sounds change like adding modulation.
Like Sine wave frequency got much faster.
Even, Trilian from Spectrasonics has same problem.
I choose TR-Juno Phat Philter from Trilian, it sounds OK.
Then alt + tab to see other window, then come back to Cubase window, then it’s sound is changed.
If I duplicate that track, then new instrument track sound is OK.
But if I do alt + tab or something(it’s not sure), it sounds changed again!
It’s very annoying. I want to know what could be cause.
