Hi Aleksey -

When the LF-Max demo was first released, it packed a major "wow factor" for me.

The more I play with it though, the more I just can't get my head around the filters.

For instance, I'm trying to use it for an electric bass guitar.  This bass guitar has an incredible tone that I'm trying not to change at all.  All I simply want to do is create a subharmonic dimension to it.

I can't seem to add this without slightly altering the essense of the tone.  Any settings suggestions to help me achieve this?  Thanks!

You should probably remove the 'Dist' signal from the output - set the DistGain to -inf.  This way you can add subharmonics alone.  However, subharmonics CAN alter the sound, and in some musical phrases sound dissonant.
