The UI is NOT to be anything close to the final UI. It attempts (poorly) to fit settings given in the interface for the existing software eq. However, the number of center frequencies, and the range of gain supported by the hardware do not fit well, so this is more of a guide.

When selecting gain, it will divide the gain by 2 to make it fit in the range the hardware eq supports. When you hear this though, it doesn't sound nearly the same. This should have been obvious, but alas, whats done is done, and short of making the whole new menu, this is still the best "fit"

When selecting the center frequency, it gives the "closest" center frequency determined by a simple subtraction.

For bandwidth, because it is a best fit system, and there was nothing in the existing UI for it, I decided to set it to wide every time. However, the hardware eq menu should have a setting for this.

I also included an array of frequencies each band supported to help with the best fit system. I would imagine the final version would not need to include this.
