Zzzorb: four-pole multimode filter with a linear VCA for extra Zzzing
Alright Devices has released Zzzorb a rather cute looking 4-pole filter with 5 simultaneous filter outputs and a built-in VCA for volume, tremolo or feedback self-modulation.
Alright Devices has pretty much built their business on the awesome Chronoblob delay which has reached version 2. So it’s great to see them bringing their unique style to the world of filters where they are naturally filling it with personality.
Zzzorb’s filter core is made up from a cascade of four VCA-based integrators with a feedback path for resonance control. Mixing these integrators together results in five different filter modes; Highpass, Bandpass and Notch and then a 2-pole and 4-pole Lowpass. These are available simultaneously with their own output.
CV control is available over the filter cutoff and resonance with an additional pitch input to the cutoff which can track 1v/oct when the unipolar attenuator is turned fully clockwise.
The inbuilt VCA has a conventional input and output, volume control and CV input. Normally the output of the VCA is added to the filter input but you can use the VCA independently by patching the VCA output. The VCA’s CV input is also normalled to the filter cutoff so you can modulate the frequency and volume at the same time but you can separate out those controls by patching into the VCA CV input.
There are a lot of filters in Eurorack so coming up with a bit of additional functionality is always a good idea and Zzzorb nails it while looking adorable. It’s available now for $230.
