add sustain modulator. increase range of release to cover all positives (though there is still a range of negatives that are duplicated). set all sound controller CCs to 0. this breaks MIDI spec (64 = middle = no change) to accommodate soundfont spec (middle of range on envelope generators is far from 'no change')
