Patches only the PEQ blocks of a single-slot Device Console export — everything else passes through untouched. Import it back through the plugin; it loads into your currently active preset slot. Filter Q is written at the plugin's 0.1 resolution.
Written for the BTR17 (gain +12/−24 dB, Q 0.25–8); other FiiO models may accept it if you edit the model attribute. masterGain carries the app's preamp; styleName carries the profile name.
Saves all four profiles (names, filters, volumes), the active profile, blind-stage slider positions, and bypass state. Loading replaces everything.
