I played around with biFilter2 and I found out it has many filter types, I mean MANY!... And they all have their own personality and sound awsome! It has got a buit in pre/post distortion knob also.. At the studio we have "Filter Freak" but biFilter2 totally blows Filter Freak out of the water. biFilter is the best filter module I have ever seen in my life, the things that plugin can do is mind blowing. I urge all of you to get with it. I am on this forum since recently, but I never hear about it although it is I think the most spectacular plugin in all of Sonar's arsenal..

I hear you. I played with it a while back and I was impressed. 

I know Eli Kranzburg really liked it in his Groove3 SONAR tut.

Tone2 makes some great products......FireBird2 is an excellent (free) synth with very useful sounds. Here's all the free stuff from Tone2:

Thanks zblip2 for posting on biFilter2.......with all the great stuff Sonar has, I wouldn't have even noticed this.  

Good stuff.  I use it for all kinds of jobs and even replaces a lot of the edge I used to place on sounds instead of amp sims.
