This sounds seriously great, man...

yeah, this is superb!

Seems, and sounds very interesting. Question to the developper or the ones who bought it: Is the audio or sample loaded in the buffer saved in the Live session and recalled when reopening it?

Also, to the developper: (sorry for the double questions, I forgot to insert in my first one). Could a pitch be added? I feel it's probably the only thing missing to this great stretcher :)

Thanks for your comments and interest.
The sample is not saved in the Live session and not recalled when re-opening it.
For sure some pitch shifting could be added, if you have some experience with Max, and don't mind the additional CPU load. For this device, I decided to keep the design focused on time stretching, though, "? la paulstretch". So the device does not include pitch shifting or other effects: if you need further processing, you will use another device downstream.
I hope that helps.

for the curious; the key to pitchshifting this is in the long-stretch.pfft inside the device. 3rd outlet of the [fftin~ 3 nofft] holds the playback bins, and if you, say, multiply those by 2, the pitch is one octave up, etc . So adding a fourth inlet to control this is a good option.
