> If you've looked at winamp.q1 you should see multiple presets in that file which follow one after each other so the file signature (winamp.q1 or a specific *.eqf file) is "Winamp EQ library file v1.1\x1A!--" (pulled that out from the disassembler) it's then a 257 byte buffer (256 + null character to terminate correctly) then the 10 byte block relating to the eq sliders (need to double-check the range base) followed by the 1 byte for the preamp slider then if there's more presets in the file, they follow on immediately after with the name block looking at the preamp slider, -12dB = 0x3F, 0dB = 0x1F, 12dB = 0 (so a 0-63 range) that seems to be the same for the other sliders (and matches 1:1 with the sdk details) and I think that's it :) in the winamp.q1 file, the 'default' entry is either a flat preset or what's been saved after customisation (in-case you're wanting to mirror the native behaviour via the preset -> save -> default action)
