[maxmsp] Speeding up an event with no pitch shift

Hi,
 
This topic of  ?playback speed control? is something that I have posted before but have had no luck with the results of what was suggested to try out. There is obviously something fundamental that I am not getting   about how the sampling domain works. 

Here is the topic again.

All I want to do is to have control on the speed of an event. i.e. a single piano key struck is an event which can rhythmically be sped up and slowed down without having it?s pitch altered. When done fast enough it becomes a single note again. Right.
 But I am surprised the see that sample playback react more like a vinyl or tape deck player. Why is this, I assume that this is because the samples are entered and read in a linear fashion ?

Coming back to my piano key example, if this were to be compared to when I select a sample size to be read in the waveform display object, it is read and ?repeated?/looped at a certain speed. All I want is to know how to have control on that playback or repeated speed. (what decide on the playback speed of this object anyways? ) It should not pitch shift , but react like a piano which is, the faster you repeat the more your sound is morphing back into a single sound again , not pitch shift. (what decide on the playback speed of the waveform display object object anyways?)

Here is a list of things I was suggested to try out and that I have covered.

-I was told to search for externals that does this. I was unlucky with the ones that I found ,(maybe I?m just not using them correctly. The last one was residency~ from the FFTease library.

-I was also told to try out the gizmo~ , which worked with the fftin~ , so I needed to first learn Fast Fourier transform was. 
So  I spend a lot of time doing this by 
 
1. Looking  on wikipedia 2. The MSP tutorials and topics 3. Peter Elsea?s notes on fft.

What I got out of it is that FFT was a fast version of DFT which was cut up sound into slices the length of a period (a wave) , in order to analyse it?s spectral content (harmonics). And as for the fft~ object, well what come out is now frenquency domain. 

At this point I start getting lost, and sort only got the grasp that this was somewhat like granular synthesis. Maybe?

-I was also told to have a look in c74 example and to check out the modsquadRedux patch. 
Interesting patch but the it also demonstrated that, as the samples were sped up the sound quality would change. Of course it would not pitch shift, but the sound quality is altered.

I also had a look at the granular and phase vocoder sampler patch example , and the results are always an altered sound.

I don?t want to be annoying with this topicI keep posting, but this is essential for what I want to do musically. And this move sounds to simple to have anything to do with granular synthesis.or fft .  

I accomplish this in ableton live simply by selecting a sample and bringing the BPM way up to 999. 
But for now ableton is really not my concern, I want to build my playback speed shifting instrument with the waveform editor that which it?s speed will be controlled by the  multi-slider.  

Sorry for the long post 
And thank you to everyone for your time and concern.
