Every track has it's own instance of Halion One. Every tom, every crash, etc has it's own instrument instance/audio channel. It's all Halion One. 20 instances, 13 just for the drums.

There are no audio plugs (comps, eq's, delays, etc) or FX sends being used on any of the instrument tracks in this "midi mix". The master bus has an enhancer, eq, and a limiter, the only plugs used. No automation except the master fade.
That's it... it's all raw midi. Any verb etc you hear is coming from the instruments, not plugins.
Frankly, I don't take midi (sounds) all that seriously.
But track a good vocal with a good mic and do a real audio mix of the stems and it would make for a decent demo.
