It's an straight line. I want to know if it happens to someone else or just me.
If anyone can try the experiment I show with the melda vst, It would be helpful to know if it happens to someone else.
For my the problem is how melda plugins work in cakewalk.
I will test with other Freqshift plugins and I'll show the result, if it works well with other plugins it will be because of how it works with Melda vst
