+1, Adjusting Community patches to our own personal setups is a must. The discussion pops up in these threads on occasion, and is worth the reminder.
This is my only minor quibble with the C4. I wish the input calibration control was global, instead of per patch. The Future Impact's input knob is set up that way and it's super handy. One quick adjustment for whatever bass I'm playing, and all my patches sound the way they're supposed to, rather than having to adjust each patch individually.
Disclaimer: just to be clear, it's a really small issue... I run my compressor before my C4 and problem solved!
