ECF-42

Filter
Reason Studios

The ECF-42 is a multimode envelope-controlled filter designed for pattern-driven filter and envelope effects in Reason Studios' ecosystem. It combines a flexible filter section with a built-in ADSR envelope generator, capable of being triggered via CV/Gate signals or MIDI notes to create dynamic, time-modulated filter sweeps. Best used as an insert effect, the ECF-42 excels at creating synthesized percussion and pattern-controlled filter modulation.

Available for:VSTVST3AUAAX
