By "ok for live" I just mean that I wouldn't use it for
routing in a recording studio.
I've played live with it without worries.
I'm expecting to completely eradicate any hum using "humfrees",
it's just the standard rack hum.

Well, I spent a *lot* of time sussing out the Alesis circuitry.

The Rane circuitry is arranged differently around the area where I'd hack 
an
insert into the Alesis, it certainly doesn't offer the exact same simple 
fix.

(here's the tech speak)
I would use the Expand Out socket as an insert send.
Then I'd sever the connection where the main bus goes to the main volume 
control.
The Expand In socket would be used for the Insert Return, it goes
to a simple buffer circuit the output of which would be re-routed to the 
main vol control.
Without an fx (or patch lead )inserted the mixer wouldn't function at all.

Note, the expand In/Out sockets are on single TRS jacks for a stereo 
signal.



You could always get a quote to have the mod done on the Rane, as Rane 
have the schematic 
available online.
