So, NAMM is over and a some products made I found to be very nice. Digitechs FREQOUT Pedel for example. You press it and it let´s your note go into what sound like a natural harmonic (5th, 8ve, etc). What I couldn´t replicate was the neverending sustain of the note to make up for an ebow. But the transition from the note to it´s "harmonic" sounds pretty convincing with these settings:
Put a chromatic Pitch stomp in slot A
Set Voice Pitch 1 to the desired harmonic (e.g. 12 for octave)
Engage Formant Shift and set it to a negative amount (e.g. -3.5)
Set Mix to -50
EDIT: Don´t forget to set the voice balance to -50!
Now the the morphing part:
In the RIG Settings page 5 set Rise Time to 1/2. And enable Tempo on page 2 (80bpm it is at the moment). This way you can change the rise time with the TAP Tempo button of the remote
Select "Momentary" on said page 5
Go back to the Chromatic Pitch Stomp page 2. Press and Hold the Switch (1,2,3, 4 or 5 - whereever your current rig is)
Set Mix to +50. Done
I raise also the gain when morphing is engaged the prolong the sustain a little.
Please forgive me for wasting your time, if someone else already made up something like this.
