I would also look into gizmo~ as well.

I would go with buffer~ and play~, this will let you "scrub" across
the sample. The trick is interpolating the audio between the control
ticks. You might want to estimate control change and accelleration to
that end.

_Mark

You could feed the output of sfplay~ into tapin~/tapout~ and change the
delaytime with line~ to scratch back in time (increase delay, slow down)
or forth (shorten delay time, speed up)… You might want to put up two
tapout~s to be able to jump to zero without clicks.
Of course you can’t look into the future, this is kind of the same limit
a DJ would have with her vinyl, but this technique would allow you to
scratch even realtime input! Scratch your voice…
