Here is a concrete example of what i'm talking about (a 3.2M-octets audiofile) :
http://www.anak-krakatoa.net/~downl/evd6shifta.mp3
I played a short impro with the EVD6 clavinet emulation ( as a logic owner that i am ) through the madshifta plug-in, using a light hi-transp but ( too) heavily reinjected !
The thing is that it sounds very subttle with such an instrument, but some of the artifacs that are typical from all pitch transposer as much as i know tend to affect excessively the reinjection loop ( both delay time and feedback level as much as i can describe the case )
...that made me think that this subbtle effect would maybe once deserves to design a pitch transposer on that purpose !
( well, at least if it isn't already the case on PC !!! )
Maybe the effect is exagerated on this audiofile, and to be honest, the use of the damper pedal affects the overall ambiance negatively in a way that it isn't really due to the pitch transposing's effect
At least just enjoy and give me a little...huh... feedback !!!!
