Did you try the PVS opcodes? They can do a lot of what Loris can do, and perhaps more besides.

In any case, the problem you mention, of morphs tending to sound like crossfades, seems like an inherent problem to me. Perhaps you could come up with a more detailed verbal description of what you think the morph should sound like, before you try to implement it. Then tell us, and we can try to figure out if it makes sense or can be implemented.

I do think morphs should sound more morph-like the two sounds do not share the same set of partials, so that the countours of one set of partials are applied to the spectrum of another set of partials. Then you would get a sound that does not resemble either of the two source sounds. If you are just changing the amplitudes of the same set of partials, or two sets of partials with mostly overlapping spectra, it will in effect BE a crossfade.

Regards,
Mike

I would also recommend pvcross and pvinterp (which seems to have been successful). 
I've personally had very good results with Loris, but I usually do Loris morphing 
from within Python, not using the csound opcodes (although it looks like they should 
result in the same audio).

The suggestion of creating an intermediate sound for the morph is also often 
successful.  I've usually just used a convolution of the two sounds for that 
intermediary.
