Pons Asinorum is a quad envelope in only 6HP! They fit all that power in a small space by using macro and shared controls. The four envelopes are linked in shape, either rising saw, falling saw, or triangle. However, each envelope may have its own time scale, programmed with the encoder. In practice it is quite quick to program and is a very useful utility modulator. Finally, the envelopes can all cycle for even quicker patching.
This module is in great shape, includes original box.
