Iriver H120 map button to switch the equalizer presets

[CyborgRD]

How i can map a button to switch between the equalizer presets like original firmware?

By editing the code and then compiling rockbox, but I'm not sure how easy this change would be.  I'd guess you would need to create new actions and then map the buttons to that.

So difficult? Sure? That is the one what i miss by Rockbox firmware.

The EQ presets in Rockbox are stored in external files, they aren't embedded in the firmware. So toggling them would require scanning the folder for preset files, determining which one is currently loaded (if any) then moving to the next one.

An EQ should be determined in almost all cases by the weaknesses of your hardware more than anything else. You shouldn't really be cycling through them, but rather just choosing the one that matches the headphones/speakers you're using at the time.

Just create an equalizer .cfg file and place it wherever is most convenient for you.  You should be able to access it with a couple of button presses at most.
