save the setting in a sound memory, then use the memory in R1, save another sound with another setting in another sound memory, then use that sound in R2 - same or different effects in both sounds at the same time via the wheel.

each sound is made up of 4 samples, so you could make one sound in R1 of piano and strings for instance, and have only the strings affected by volume when moving the wheel, and have the piano not affected, or affected with a different function via a filter so as the strings got louder the piano got brighter.

glide shifts a semitone via a footswitch.

it's all programmable and in the manual.
