I updated two things:
1. As a few users have noticed - the plugin is not transparent in default(zero) position.
I didn't like it too, so I found solution that fix this.
I have changed Volume section to Levels. It features two morphable knobs - Wet Level and Dry Level.
Have fun with that.
2. I have added dropdown menus to HP Freq, HP Spread, LP Freq and LP Spread.
Just click on knob's name to tune freqs to musical notes!
It's even possible to make chords this way!
