Instruo Aradh Ladder Filter

By popular demand – an exciting new take on the legendary transistor ladder filter. Introducing the Instruō àradh, the long-awaited successor to the first Instruō low pass filter, tràigh. Expanding on tràigh’s classic functionality, àradh adds a VCA with pre or post-filter routing options, an envelope follower, a comparator gate, a strike input with variable decay time, and a plethora of user-definable voltage-controlled parameter combinations. Whether you’re looking for voltage-controlled resonance, pre-gain filter saturation, noise gate functionality, dynamics processing, or even an envelope follower, àradh can get the job done – a true sound-shaping powerhouse in only 6 HP.
