This is an easy trick do to. I usually do it without resorting to any
plugins of that kind.

Simply do a bounce of that part of the track, place it in a sampler (I
use EXS24 in Logic). Playback via MIDI and use the pitch wheel (or draw
it using hyperdraw/automation) to slow it down (to get the full 2
octaves you should start playback at pitch +12 but not actually
transposed). It may be necessary to do a few automations (reverb bypass
etc.) at the playback start point and stop point.


thanks again.
