Hello Tom,
Yes ! you can use the foot switch to bend a note. But you can also use the after touch feature. Press F3 for utilities.F2 for aftertouch. Look at F9 for
the slide.Use the cursor buttons to adjust slide .
Experiment with it and good luck.
I have also used the portamento feature with a steel guitar sound. That feature combined with aftertouch is great. Take Care Dan O
