@Iain: Yes, how silly of me, the crossfade is to avoid the clicks. I never thought of it that way. Hence the pleas to ignore my naivete. Thanks for sharing the patch with me. I shall go through it and I'm sure it will clear out a lot of things.

@Colet Patrice: Hey, thanks for writing to me. Well, the reason I want to do it in pd is because I wanted to be able to switch routing so that I can move sound around however and wherever I want. I want to be able to switch functionality of the same set of sliders to control all sound, in all directions. Also, I wanted to incorporate other functions like latency meters and allowing for Q'ing to headphones depending on which mix one is currently working on in the mixer, or even independent of that actually. It should be fairly functional without having too much detail, simple because I'm pressed for time!

Thanks,
Rishabh

Hello Rishabh,
 you should be able to use jack for local and distant sound system,
no need for internal drivers through pd.
In both adc~ and dac~ each argument is the number of audio voice coming from/to jack
eg: [adc~ 4 1 2 3] would output from left to right the inputs 4 1 2 3 from jack interface
but if sound processing is just about amplitude, you don't even have to bother with pd (sorry pd-list ^^)
because jack mixer would be enough for that.

for building a virtual mixer it's really easy in pd, it's just a slider with default values connected to [dbtorms] for controling the amplitude
of a signal coming in [*~]'s left inlet by connecting it to right inlet after a conversion from message to audio with the help of [line~]


[adc~ 1]
|
|[hslider]
| |
|[dbtorms]
| |
|[pack 0 10]
| |
|[line~]
| |
[*~]
|
[throw~ master]

[catch~ master]
|
[dac 1]

this simple example is mono, use [catch~ master-left] and [catch~ master-right] for retrieving two voices coming from [pan~],
all signals are mixed through [throw~] and [catch~] bus.
