Well, certainly for me, basic op amp mixer circuits are as easy as it gets.
I like the idea of an output mixer as well. But, I have a question for
P.S., J.H. or those easily more qualified than me. Is there a functional
limit to the number of input connections for an op-amp in a standard summing
inverting mode? We see 3 and 4 all the time. But, what about 8 or 10.
Does that work just as well? Or, does one reach a point where two the
number of inputs justifies dividing them between a couple of summing
circuits and then summing the output of those?

Subject: [motm] Output Mixers and other ideas
I'm going through the output mixer dilemma as well. I've tried
using a Samson 16 x 2 mixer in a 2 rackspace unit with a headphone
out. Unfortunately the Samson mixers are the only units I have
found which refuse to coexist with the balanced line AC in my
studio. They hum like crazy.
For recording I go straight from the alst module into my Apogee
converter.
I'd like to see an output module with a headphone amp and balanced
line outs. Two outputs would be enough for most people but perhaps
more would be nice to have for those MOTMers who like to perform
live with multiple speakers.
An input module would be nice as well. I'd like to see a mic input
preferably with phantom power available as well as a couple of line
level inputs. Maybe it could include a follower.
A third idea would be to possibly adapt one of those low cost tuners
like the Korg into a tuner module, possibly with an A440 reference
as well.
Idea number 4 would be a universal buffer module which could adapt
ins and outs from rack mount units like delays and effects into MOTM
level signals. Sort of like Stooge Moe's buffer for the
expressionist.
Just throwing ideas out there.
So many ideas and so little time.
