The pitch effect is mostly uniform. There are a few places where the pitch "pattern" does something different - but I think if you setup a PEG to handle the pitch effect (to always do that double "flutter") - then that would be good enough. For that lead part - make it so a certain high velocity would invoke the PEG flutter sound and a normal velocity would have the normal flat PEG curve. The response in volume to velocity should be set such it is not velocity sensitive so the hard hits for the flutter do not drastically stand out from a volume perspective.

That's one way to do it. Alternatively, you could construct a motion sequence which is velocity sensitive. Then use that to apply pulses/curves to pitch as a destination. This would be non-looped and the last value has to return the pitch offset back to 0.

I'm suggesting using velocity since it's, to me, easier to deal with than using a button.

Hi Roberto,

the pitch envelope and in this way modulate the pitch of the part ? or other solutions ?

since only one note in this intro needs the effect in always the same way, you can assign a Part or an Element with Pitch LFO to this key. I programmed the voices for this song a time ago for a customer on MOTIF XF. The benefit is that you can use the left hand to play the other synth. 😉
