This Combinator FX is a great tool and very fun to use. I was inspired by the classic UREI/UA 1176 Blue Face Compressor.

This rack includes a fully functional and well callibrated compressor, including: Input knob, Output knob, Attack knob, Release knob, and the 4 Ratio level buttons with 4:1, 8:1, 12:1 and 16:1 settings... (this was really tricky to program).

The cool thing about this , is that you can either use only one Ratio setting or you can combine the ratio levels however you like... this even lets you use the 4 buttons together, that way you can get to a extremely squashed compression with a maximum Ratio of 40:1.

There are no functions on the left side wheels.

This patch works from reason 3 and above.

Enjoy!
