Voodoo Lab

I recently purchased a PX 8 Plus and love the preset mode but I'm having trouble using its midi capabilities. I only have 1 midi pedal which is the Source Audio Collider. I am new to midi and after reading the manual for the Collider and PX8+ as well as other posts, I'm still stuck. My goal, for example is to have a preset on the PX8+ that uses a slap back delay/reverb sound and then another preset on the PX8+ that has a shimmer sound.

Can someone please outline the steps/ connections/ buttons to press/ needed to do this?

I do have other drive/ effects pedals in the other loops and put The Collider in loop 8.

Thanks so much
Marcel

Hello, I just gotthe PX 8 plus pedal power/board package and am confused on the order of using the insert send/return loops. For example, I have a boost pedal that I want to use in loop 1. Does the Send of loop 1 go into the input jack of my boost pedal and then the output jack of my boost pedal goes into the Return of Loop 1? ( Basically each pedal is connected to its own loop)
I did this for all my pedals and am not getting any sound.

Thanks and if there's any charts/diagrams or videos explaining this it would be great.
