OK, I will try (after my work finished today) and let you know. Many thanks again for your advise.

Hi Promidi, Thank you for your comment. I am using UR22 with WASAPI / 24bit / 96khz / minimum samples. Why I use WASAPI is I sometimes use USB Speaker (JDSound OVO) I am not sure if my Windows 10 is fully patched, but I never delay the timing intentionally at least. I happened to check the Hardware drivers just a couple of days ago so all should be fine. Sampletank 4 and other VST are working fine under the current environment.

Ample Ethno Ukulele always clashes when I use strummer function. Would someone suggest me which preference I should review? Or let me know the preferable setting. I downloaded the trial version just today. Each time I try some strumming patterns in the strummer screen, the screen freezes suddenly. I have no way but to shut down Cakewalk. Also, I have to reboot my PC because it becomes unstable to use mouse left click. I think my PC spec is enough (Windows 10, Corei7-9700, 32gb RAM). Also, I never had a problem with Ample Guitar M Lite.
