HOW TO ON YOUR K2700 · 2046 Editor Template
The factory does not route Trk B while ~A to a sound on its own: set one up on 2046 Editor Template and hear it on the pitch.
In Program mode choose 2046 Editor Template, a plain one-layer program to build on (KEYPAD, 2046, ENTER).

Press EDIT, then MORE and DSP MOD. On the Pitch row set Source 1 to FUN2 and its Depth to 1200 ct: FUN2's result, −1 to +1, now bends the pitch up to an octave either way.

MORE, then LFO+. On the FUN2 row set Input a to MIDI29 and Input b to MWheel.

Move to Function and turn the Alpha Wheel to Trk B while ~A.

Hold a note and move the mod wheel: the pitch follows it. Turn the Variation button on and move the wheel again: the pitch stays where it was until Variation is off.
Press EXIT and answer NO to leave the factory program as it was, or SAVE to keep your version on a USER ID.
