Advice on setup needed
 

Hi, I am looking to start performing live using the following instruments and hope you would be able to assist me.

Instruments:
Cort Acoustic Guitar
Ibanez Electric Guitar
Arturia MIDI keyboard (Essential 88)
AKAI MPD218
Presonus Studio Mic
Normal Mic

Equipment:
Apple Macbook
Presonus Audiobox USB

Pedals:
Boss RC-30 Looper pedal
Boss FS-6 Dual Foot Switch Pedal
Multi-FX pedal

What I need to know:

Would it be possible to run all instruments through the equipment in the following way:

Attachment 7347

What I need to know is if this will work as I am on a budget and seeing as most venues nowadays have their own audio systems set up, I feel it is not needed to purchase my own mixer and speaker system. However, if it would be the best I will see what I can afford until I can upgrade at a later stage.

The goal: To be able to loop all instruments through the Boss RC-30

PS: Sorry for not specifying all instruments....

Thanks!
