Mouse sensitivity and controlled parameters

[Giuseppe]

Hello everyone,
there's a strange thing I'm noticing when using a widget (knob) to control a modulator, but I guess this would apply to other controlled parameters as well.
Simply put, if I drag the widget with my mouse abruptly, some values of the controlled parameters are skipped. In the case of the modulator, I'm controlling the Pitch of the sampler (-12 to +12 semitones) and if I move the mouse very quick from default value (0) to the minimum or maximum, I can see that the modulator intensity stops randomly at -4, -7 etc. It doesn't happen if I drag the mouse slowly.
I partially solved it by increasing the mouse sensitivity in order to make the widget less "slippery", wondering if it's a know behaviour or if there's something amiss in my script.
Regards,
Giuseppe
