The equalizer got some needed work in beta 5. I added the ability to add, save, and delete presets. You now can manually enter gain values for each band. Just long press the dB text and there will be a popup to manually enter a value. I also readded the ability to use external dsps and open the stock audio settings ui (if your phone has one) straight from GMMP.
Beta 5 was pushed to google play tonight but will take a few days to get approved just like the last 2 updates.
