The new Zzzorb module from Alright Devices is a four-pole multimode filter plus a linear VCA in 10HP.
The filter core is made up of a cascade of four VCA-based integrators with a feedback path for resonance control. The integrators are combined in different ways to provide five simultaneous filter outputs:
The built-in VCA is a neat way to apply a volume envelope or tremolo to your filtered signal. You can even use it as a feedback or self-modulation control by passing one of the filter outputs through it.
It provides CV inputs and attenuverters for controlling the VCA level, filter resonance, & filter frequency. Additionally, it has a filter pitch CV input with a unipolar attenuator. When the attenuator is turned fully clockwise, the filter frequency tracks the pitch CV input at one volt per octave.
The output of Zzzorb's VCA is normally added to its filter input, providing a quick way to manually or electrically control your signal's level. You can break that connection and detach the VCA from the filter by connecting a patch cable to the VCA output.
The VCA's CV input is normally connected to the filter's frequency CV input so you can easily modulate the filter cutoff and the VCA level with the same signal. You can break that connection by connecting a patch cable to the VCA CV input.
