Slight vibrato buglet?

[jamos]

Hey all. New Pro 3 SE owner here.

My instrument (01642) has an interesting quirk. Occasionally, I get a light vibrato from LFO1, even when the mod wheel is at 0 and the LFO amount is set to 0. It goes away when I calibrate the oscillators. I have calibrated the wheels as well and this does not change things.

Is this a common thing? I find it puzzling, and since there is a workaround I am loathe to return the instrument just for this.

Ooh. I figured it out. It was a mod wheel calibration problem. Turns out that when I pull it down and hold it, the mod wheel is slightly past its true lower limit; it springs back a smidge when I release it. So I recalibrated with the mod wheel resting at its lower limit, not pulled tightly against it, and everything seems fine.
