Pittsburgh Modular Lifeforms Dynamic Impulse Filter

The Dynamic Impulse Filter, from Pittsburgh Modular, utilizes an entirely new, all analog design to replicate the impact transients and vibrancy of a percussion hit. The result is a versatile filter module that sounds natural and energetic. The Dynamic Impulse Filter works in one of three modes: resonant lowpass filter, high quality VCA, and a combined lowpass gate mode that manages both timbre and loudness at the same time. The core of the filter uses a Sallen-Key topology to produce a smooth two pole filter that will self-oscillate at high resonance settings. �

The unique design of the Dynamic Impulse Filter replaces the vactrol with a modern analog circuit created to replicate and expand on the signature sound of the vactrol. The response time of the Dynamic Impulse Filter is not static like a vactrol; instead it is tunable allowing the response of the module to adapt to any musical context.�

The Response output of the Dynamic Impulse Filter can be used to control other modules that utilize vactrols. The Response output superimposes the variable Dynamics Response onto vactrol based modules allowing the response of a static vactrol to become adjustable. This opens a range of new possibilities for other modules that use vactrols.�
