I recently had to perform a live an EP of electronic (experimental/neo-classic) I released. Vocals are being radically altered through an FX chain.
Despite that I did some tests in my home studio without feedback, once at the rehearsal in the club, I encountered a massive feedback problem (+ that night the usual PA was replaced by a sound engineering student) and I had to cancel all the tracks featuring vocals.
I am very new at performing vocals and I would like to know what I am doing wrong and how to find a way around or compromise to still be as near as possible to the EP vocal's vocal processing while avoiding any feedback issues.
My setup is the following:
IN: Mic → Scarlett 2i2 (soundcard) connected to MacBookPro/Ableton
OUT: MacBookPro/Ableton -> Scarlett 2i2 (soundcard)
FX on vocals
1.utility (raise volume up)
2.vocal control multiband compressor
5.Reverb (25% wet)
6.Tube amp simulator
Basically I then simply layer my live vocals on top of the instrumentals and chorus background:

The subwoofer was on the floor and the rest of the speakers were suspended 1m50cm above the floor. I had two behind me (my setup was put on the table in the picture), and two others cornered in the space.
