You never described the problem around your musical intent but jumped right into what appeared the problem to you.
Now it seems that what you thought was the problem, ended up not being the issue preventing you from getting to your musical intent.
Without you articulating what your music intent was or what you heard compared to what you expected, makes this entire thread a rather frustrating experience for those like me, who have spent their own volunteer time in an attempt to help a fellow music maker.
In a last attempt to get this deeply unsatisfying feeling out of my head, let me take a final shot at asking you a clarifying question / along with a guess at the real problem:
Are you trying to use pitch bend (with the mod wheel or via drawing) to create a realistic guitar string bend from a guitar sounding VSTi?
And is what you’re getting as a sound either no pitch shift or what appears to be a jump to a different note?
If this is the problem, then I may have an explanation:
While most synth-oscillator based plugins feature very good pitch bends,
quite a few sample based VSTi plugins seem to have unsatisfying implementation of pitch bend. – This has nothing to do with the DAW, but is simply a lack of programming in the VSTi plugin.
If this isn’t the underlying issue, I’m out of guesses what you are trying to achieve and you’d have to explain the real issue some more.
