Noise Engineering Quantus PaxQuantus Pax is a four channel precision adder, buffered multiple, and polyphonic transposition utility. Each channel has two CV inputs and can be further modified by the three Xpose inputs. QP is made with high quality low tolerance resistors for unbeatable accuracy. Patch wide key changes, polyphonic movement, mathematically derived melodies, and more are all to be had with this simple but useful utility.
