(mac only)
This is a simple, but high quality pitchshift device using the diracLE~ external. It can also correct formants for a more natural sound. The formant parameter can also be used without pitchshifting which can lead to some interesting results.
The latency is quite big (10048 samples), but this is automatically compensated for by Live.

Limitations:
- samplerate should be 44.1k or 48k
- smooth parameter changes are not possible, though abrupt parameter changes should not give a click
- latency is too high for live audio input
