I guess we could do a pre and post compressor output option. It's just a
case of hooking up a couple more jack outputs to the signal chain.

I can see tow options for enabling it in the interface:

1: Add 12 new jack outputs for pre and post
2: Add 6 new outputs for pre and post and provide a "pre/post" aux/send
toggle.

We could also add volumen sliders for the output on each send so that
would probably require a secondary window or a panel that could be hidden
and slide in/out if in use.

Any thoughts on UI functionality?

I might have some time to add this over the next month.
