It's in the Parameter Guide p50 but as usual they omit a vital step to increase the AMS 'intensity' (P2:pitch) to +/- 2.0 (for a +/- wholetone bend).Selective pitch-bend, using only the joystick
You can also use a single AMS source as both the Control Source and a value source:
1.Set the Control Sourceto JS X.
2.Set Control At Note-On Only to On (checked).
3.Set the Threshold to 00.
4.Set Below Threshold to AMS A:JS X.
5.Set At & Above Threshold to a Fixed Value of 00.
6. On the OSC Pitch page, assign the AMS Mixer to control the pitch.
7.With the joystick in the center, play a chord, and hold it through step 9.
8.Bend the joystick to the left, and then play a new note above the chord.
(If the pitch changes, go to the OSC Pitch page and set Pitch JS(+X) and JS(–X)to +00.)
9.Use the joystick to bend the pitch of the new note.
The new note will bend, but the original chord (played before you bent the joystick down) will not.This method is particularly good for bending the top note of a chord up to pitch.
Anything played before touching the joystick is unbent, as soon as the joystick is moved anyway left the next note(s) are bent according to the X-left point. Chords sustained with a damper pedal, will sustain unbent, anything played after a joystick X-left move is bent.
