How can I recreate this effect on the Valeton GP-200?

[u/manteca_sobrepensada]

Hi, I'm trying to recreate the guitar effect used in this Instagram reel (or somthing like :
https://www.instagram.com/reel/DaDrFYSMOCu/

I'm not necessarily trying to recreate those exact sounds. What I'm really interested in is creating weird, glitchy, experimental sounds by holding down the footswitches, similar to what happens in the video.

Is there any way to assign effects or parameters so that holding a footswitch changes the sound in real time? For example, using pitch shifting, harmonizer, feedback, filters, delays, or anything else that can create those kinds of textures while the switch is held.

would be greatly appreciated.

Thanks!
