When the hardware wavetable synthesizer of an Creative SB Audigy or SB Live! card (with emu10k chip) receives the MIDI SOFT_PEADAL-press event (?? 67 127) the appropriate voice is attenuted. Unfortunately when the pedal is released (event ?? 67 0) the voice does not get it's original volume again.
The attached patch fixes this problem by analysing the value (0 or 127) of the midi control event and resetting the effect register in case of a release event. I'm not 100% sure if the code to reset the register is correct but at least it works.
