Hello, i think it’s really depends about Music Genre according to the app notion of Analog Rytm. I would not use it before to really understand the AR Structure and Saving. When you get it, and handle it just fine, then you can introduce some things on top of what you understand perfectly.
Yes Overbridge is cool, when the marriage is successful with the computer you have. (system requirement, specifications match well)
If i were you i would introduce a portable and light mixer like a small mackie to get instant mixing, good gain staging or at least more easy to handle… on a stage. It’s not really that expensive and from my point of view it’s really important. (You can when booked to asking for one) But in the prepare of your LIVE writing, i would do that… (and if you have 2 aux effects with return it will be perfect with your two Strymons so you could find something useful with the AR individuals outs to deal with Effects Routing)
Also, as @Silmae told there’s a compressor, and a good one. But you can want to compensate the loose (body & punch thinner) of some frequencies in the low end AND a EQ after the compression in LIVE situation is nice so basically your mixer can be very appreciable for that matter 
I don’t know where you are but in a lot of town there’s Concert hall with rehearsal studio, and you can Rent a rehearsal/repetition studio so you can get an idea of a middle sound system and adjust few things. But at the END when you will play your first LIVE you will have 30-45minutes to adjust things with the person in charge of the Sound System.
Try to not introduce the computer in your Live rig it USUALLY where coming problems. (Not the one you can’t deal with but more it’s complicated and less FUN and Lose confidence appears…)
Accept to start simply with something efficient and accept and understand you will have a progression curve it will make you better and better, the one you consider as your MASTER, are all start somewhere and was probably not as talented as today when they start
