-- * description : 
--  
--  lorismorph morphs two stored sets of bandwidth-enhanced partials
-- and stores a new set of partials representing the morphed sound.
-- The morph is performed by linearly interpolating the parameter
-- envelopes (frequency, amplitude, and bandwidth, or noisiness) of
-- the bandwidth-enhanced partials according to control-rate
-- frequency, amplitude, and bandwidth morphing functions.
