Using MIDI to change parameters within stomps with an expression pedal

hey there,

I am using my kemper along with a boss es8 effects switching system.

so far, i am just sending MIDI from the es8 to switch stomps off/on.

I have an expression pedal and an ehx 8-step that control parameters within a few of my midi pedals (h9/hog2/timeline).

I would really like to use the expression pedal to scroll through the intervals on the harmonic delays of the kemper

I see it is possible to change delay and reverb mix and feedback with MIDI cc, but is there a way of delving into the other stomps' parameters too?

any help greatly appreciated!

...seems other stomps can be controlled using the kemper's morph feature, but not with the midi available with an es8.

these don't include melodic intervals though...

Thanks for your reply.

I am limited to what the boss es8 is capable of with midi and unfortunately it goes nowhere near that level of detail.
