In this video, Mark Verbos introduces the Verbos Electronics Haas Zone Processor.
The Haas Zone Processor enables chorus, flange, phase cancellation, doubling, ADT, waveshaping and other effects.
At the core is a multi-tapped digital Delay Bank, largely influenced by vintage studio processors including the Marshall Time Modulator. Tap1 can be switched and swept from less than 1mS up to 20mS. Tap2 is chained from the output of Tap1, adding an additional 1mS-20mS. Tap3 ranges from 9-42mS. In addition to having their own full volume outputs, all 3 delay taps can be blended with the Dry input signal in a voltage controlled mixer.
Also included is a Bandpass filter, built from a 2 pole hi-pass followed by a 2 pole low-pass. Bandwidth can be swept from very narrow all the way to full bandwidth. Frequency can be swept across the full audio range and voltage controlled through a bipolar attenuator.
To the left is a Voltage Controlled Oscillator, similar to the modulation side of a Complex Oscillator. Included is a Triangle, Square and Sawtooth wave that range from 0-10v. The Frequency can sweep from more than 1 minute per cycle all the way up to audio range and tracks volt/octave.
There is an envelope Follower on the input and both it and the triangle output from the Oscillator are normalled to the c.v. inputs on the Delay Time. The output of Tap3 is normalled to the input of the Bandpass filter and the output of the Bandpass filter is normalled to the Feedback In. Through tweaking the Delay Time, Oscillator Frequency and Bandpass Frequency multiple resonance points can be accentuated.
The Haas Zone Processor is intended to be used as an effect, inside a patch as waveshaper or as a voice on its own.
Pricing and Availability:
The Verbos Electronics Haas Zone Processor is available now with a street price of about $800 USD.
Great timing. I had just spent a whole day reminiscing about the Marshall Time Modulator and searching if anyone else had attempted a recreation of it. This definitely looks interesting.
Experimenting with voltage controlled short delay lines is such a blast but it really can take forever to dial in. The MTM always seemed to have the advantage over whatever i was using of sounding amazing (or at least novel) on all sorts of settings.
