Proteus Auto Filter

From the ashes of the original Prometheus, the Proteus embraces a very different philosophy. In short, the Proteus is what many people wished the Prometheus had been: simpler and easier to use on the fly. The envelope filter mode is much more “funk” than “shoegaze.” The step filtering is pure random sample hold. No ultra-fine tuning required. Just tap to the beat, and Proteus does all the thinking for you.

Where the Prometheus was a mad science project run amok, the Proteus is exactly the opposite. Controls are simple, obvious, and do exactly what you expect,every time.

The low-pass filter does not cut out frequencies below the cutoff point, so the low end always stays intact.

Control Matrix

• Bypass Switch: Turns the effect off or on.
• Tap/Mode Switch: Tapping the switch in time starts the sample/hold filter. Holding the switch down for one second switches back to envelope filter mode.
• Frequency: Filter resting point.
• Depth: Filter modulation range for both envelope follower and sample hold mode.
• 1-2-4: Step multiplier. One, two or four steps per beat (sample hold mode only)
• Bonus: Use the internal switch for a band pass filter option.

History

This pedal is the result of our multi-product R&D operation, Project Quasar. The design philosophy behind the Proteus was to create an “Anti-Prometheus.” Now you are probably saying to yourself, ‘Well they are both filters.’ In fact the filter circuit in Proteus is exactly the same. The design philosophy was all about user control. Options vs. ease of use. Even synth nerds can spend hours tweaking knobs and never cover everything the Prometheus can do. The Proteus is straight-to-the-point filter that anyone can figure out in a matter of seconds.
