All of the NI stuff is pretty special.

If you go and buy a copy of 'Computer Music' magazine then on the cover disk it has a couple of nice free versions of

Rob Papen Blue

BLUE synth: FM Synthesis, Phase Distortion Synthesis, Wave Shaping Synthesis & Subtractive Synthesis

and u-he Zebra

u-he.com - Zebra

As far as I know these are not cut down versions of the original (non CM) versions

The Zebra is really very very good
