Seeking live performance advice from live sound engineer

[mhat]

I am putting together a set of material I've been working on. The ingredients are:
Me
My laptop
Ableton Live
Firepod
Midi keyboard
Beringer midi foot controller
Vocals (via SM58 to Input 1)
Acoustic guitar (via SM57 to Input 2)
Electric guitar to small tube amp (via SM57 to Input 3)
Etyomotic in-ear headphones (my monitor)
I have programmed drums and bass and etc parts that I play along to. Some songs I do piano, some guitar, some I switch in between, some I set up loops...etc
My questions:Do any live sound engineers foresee a problem of me sending a stereo mix to the board and I handle all the levels inside Ableton? I am monitoring through head phones so I don't have any stage volume to compete with. Will my mic'd acoustic be ok (feedback)? Have I overlooked something?

I'm not a live sound engineer, so I'm perhap's not allowed to answer this...

(BTW, there is no live engineer on this board, we're all absolutely unexperienced people just joking around and waisting time with useless and unending strile discussions... )

jokes aside,

There is nothing wrong with your setup, just pay attention to the plugs you put on each channel (compression, limiters...). The feedback problems can occur wether you mix "in the box" or on a real console, but inserting limiters in the signal chain will prevent you from real problems. (you still have to watch out for your mics and stage monitors position though, limiters or not )

I would advise you to get a midi controller with faders, so as you can adjust the different levels on the fly, like you would do with a real console, though,

because when you got lots of audio tracks in ableton, and when you need to lower or rise the level of a single track, it can be tedious, time consuming and buggy to search the right track and tweak it with the mouse, when you got a guitar in hands or whatever else...

(behringer bcF, stuff like that, you can find some fader controllers for cheap.)

^^^ what he says

generally feedback you can't ever for sure eliminate beforehand, it always MIGHT occur, but reading you use SM57/58 you already use very feedback resistant mics, pretty much ideal for stage use...

also, you mentioning in-ear monitoring, another plus to eliminate feedback, stages are usually setup that the PA is blasting from the stage edge towards the audience away from the artist... hence the open monitors blasting into your mics are the ones usually causing feedback... (which you don't use)

that might be a different in clubs that typically hosts DJs, those PAS often are pointing also towards the DJ booth or stage... and can cause feedback...

basically from your described setup, it sounds pretty much being on the safe side as much as you can beforehand, the rest you need to figure at the venue and it's circumstances and adjust your levels accordingly, rule of thumb, start slow and low and work yourself up (level wise)

good luck

+1 for some physical faders or knobs for adjusting your mix/monitors live on stage - just a couple or as many subgroups as you feel comfortable with, so you're not fishing for them with a mouse.

the short faders on a lot of the current MIDI kbds will be fine, or another good cheap and sturdy option is this:

I forsee no problems.. just be sure to mute the guitars when not playing .. they pick up resonances while not being played.. and can cause feedbacks

The only real use of a sound engineer would be if you output several channel for the vocals, guitar, and other stuff.
