Change in tone selecting mod destination with mod wheel down

Hello all, New user here.

Last night i was creating a new patch with the calibration patch as a starting point. I hadn’t made any changes to the calibration patch and i noticed that when my mod wheel is all the way down, LFO rate at zero and mod amount at zero, If i cycle through the mod destinations the tonal quality of the raw waveform changes subtly. When the destination is pitch it sounds ok but switching though filter, wave and osc2 it seemed to loose a bit of the harmonics.
Not a big deal, Its hardly noticable.
Is this normal? Does it happen to anyone else?
Thanks
P.s When i turn on my Phatty it outputs a tone via the output, Like a pitchbend down for about 1 second. Is this normal?
I’ve only just noticed it as i don’t usually connect an output until i turn it on. When the output is connected and turn it on i get the tone.
Again, Not a problem, Just wondering.
