; Morph the partials in meow.sdif into the partials in clarinet.sdif over the duration of
; the sustained portion of the two tones (from .2 to 2.0 seconds in the meow, and from
; .5 to 2.1 seconds in the clarinet). The onset and decay portions in the morphed sound are
; specified by parameters p4 and p5, respectively. The morphing time is the time between the
; onset and the decay. The meow partials are shfited in pitch to match the pitch of the clarinet
; tone (D above middle C).

; Morph the partials in clarinet.sdif into the partials in meow.sdif. The start and end times
; for the morph are specified by parameters p4 and p5, respectively. The morph occurs over the
; second of four pitches in each of the sounds, from .75 to 1.2 seconds in the flutter-tongued
; clarinet tone, and from 1.7 to 2.2 seconds in the cat's meow. Different morphing functions are
; used for the frequency and amplitude envelopes, so that the partial amplitudes make a faster  
; transition from clarinet to cat than the frequencies. (The bandwidth envelopes use the same          
; morphing function as the amplitudes.)
