All voicebanks are glitchy when they sing

I havent tried anything other than a vsqx, but everytime i try playing a vsqx on synth v it just glitches out when they sing, I mostly use eleanor forte, but genbu and renri are glitching out too if you can please fix this

What’s kind of setup do you have? DAW, CPU, ram etc. Have you any additional plugins running at the same time?
It sounds like something is eating a lot of resources. If you open up task manager, you should be able to confirm CPU and memory usage at playback.

Maybe you should turn off “Convert Out-of-range DYN to voicing” option when you import vsqx or use eraser to fix the voicing parameter.
