For those of you who are interested in DJ/CJ tools, tools for live
performance, and LADSPA plugin guis, you may be interested in a new app 
we are creating based on the code from JAMin. It's called jackEQ. The 
core is a new plugin Steve Harris released recently called DJ EQ which 
is a three band EQ commonly found on dj mixing consoles. It's currently 
only available in the swh-snapshots directory.

jackEQ is in its infancy but we now have 4 stereo (8 mono) i/o channels 
with eq, meters and independant gain control. All channels are routed to 
a master and monitor output or you can take them direct out too.

I would like it to be able to do all these things eventually:

2 x cross faders (all channels and combinations)
unlimited channels.
jack port connection ala freq tweak style
Beat counting support
controlled via keyboard or other dj console.

With the above I can now use my four channel (USB) card as a complete 
djing tool. You could also use a two channel card in a similar (mono) way.

The monitor is assignable to seperate output channels than the master
outs for simple previewing of tracks. All the channels are routed 
through it with a simple button press if needed. The eq's are adjusted 
before the signal arrives at the monitor.

This is how I intend to use it:

mon    ch1 ch2 ch3 ch4 echo
out1&2        out3&4
              external--------->sound system


I have been wanting this functionality for the past 4 years. Now I can 
start mixing demos/albums from the comfort of home.

Big ups to Steve for providing the bulk of the knowledge base, the JAMin 
crew for making the gui happen and the LADs for keeping it real with da 
open source flavah.

If you don't know this you don't know JACK.

Being on stage with the band in front of crowds shouting, "Get off! No!
We want normal music!", I think that was more like acting than anything
I've ever done.
