Hi, I would like to suggest the a Solo-lock function.
This for 2 reasons:
1. It could be used as a effective bandpass filter.
2. Sometimes its preferable to not have to hold down the solo button(the headphone symbol).
Maybe shift-click (or any other modifier) could toggle solo on/off for selected band?
Thanks for a fantastic eq by the way..have changed my ways of eq:ing a lot (to the better)
