The Yamaha AN1x Synthesizer mailing list

Hi

I would guess Gary is the natural recipient of this message, but of 
course anybody is welcome to comment. In p.36 of the PLG150-AN manual 
under Mrph CtrlNo it says: 

"...MIDI Controller....is used to 'morph' or crossfade between two 
different voices."

To me this is a prime example of how new terms are being introduced 
and used without having been sufficiently explained in the first 
place. I think the first time I saw the term crossfade was in the 
70's when I got some pieces of Serge modular synths. Crossfade simply 
meant and still means to have one voice or oscillator or other source 
of sound fade out while another is fading in. IMHO morphing is 
something totally different. From what I can recall, it was first 
used in the movie industry to have one visual object gradually 
transform into another, "Terminator II" has lots of these effects. 

Translated to synthesizer techniques this should mean that one sound 
morphs into another by gradual changes of parameters like waveforms, 
envelopes, filter settings like center frequency, resonance, etc. Am 
I right, or ....?
