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.
Boolean MIDI controls should interpret 0..63 as false and 64..127 as true. Thanks to Clemens Ladisch for review and correction.
