The only way to get a usable sine wave for vibrato in the Note Expression Event Editor is to set global snap to a small value (1/8 or 1/16). However, for this to work you have to turn on global snap, which automatically turns on Horizontal Snap in the Event Editor, which destroys the sine wave. Turning off the Event Editor horizontal snap turns off the global snap, which prevents drawing a usable sine wave (it then draws a very long half wave). Anyone know a workaround for this, or is it a bug?
As far as I know, the Event Editor Snap and the Key Editor Snap should be in sync. Why/how does it destroy the sine wave?
Could you attach some screenshots and step-by-step process, please?
