D16 Group releases Pulsatec - Analog Passive Equalizer Plug-in

D16 Group has announced the release of Pulsatec, an Analog Passive Equalizer plug-in.

Pulsatec - Analog Passive Equalizer

Pulsatec is a plugin modeled after classic passive equalizer units. It is designed to deliver the tonal coloration associated with vintage analog gear. The plugin supports simultaneous boosting and attenuation within the same frequency range in the low band- a technique used to shape frequency content in musically pleasing ways.

It features separate low-mid and high-mid frequency controls, with the ability to fine-tune the bandwidth of each mid band. In addition, a high-frequency attenuator is included for further tonal shaping.

Pulsatec also provides a real-time analyzer that displays both input and output frequency spectra, with an overlaid EQ response curve to help visualize the effects of adjustments.

Additional utility functions include output volume control, output metering, and a quick bypass switch for efficient workflow.

The interface is scalable and supports MIDI Learn functionality, enabling integration with external control surfaces.
