Filter SEM is designed to enhance other synthesizers by expanding their sonic capabilities. Originally inspired by the classic Oberheim SEM's multi-mode 12dB per octave filter, this plugin adds polyphony, thickens sounds, and supports sequences alongside main synth parts. Its signature filter shapes diverse tones that are difficult to achieve with other synths, making it a valuable tool for both studio production and live performance.

This plugin faithfully recreates the iconic filter from the Oberheim SEM with precise modeling of its low-pass, high-pass, notch, and band-pass modes. Beyond accurate emulation, it introduces modern features such as a dry/wet mix, noise oscillator, soft clipping, and an envelope with attack, hold, and decay stages. These additions provide enhanced control over sound design, allowing producers to craft rich textures and dynamic rhythmic content using its built-in sequencer and modulation matrix.

Filter SEM’s architecture is built on advanced analog modeling technology, ensuring authentic sound quality and responsiveness. All parameters are MIDI CC controllable, supporting seamless integration with digital audio workstations and live setups. With 40 presets from top sound designers and extensive modulation options, this plugin offers a powerful and expressive filtering experience that can transform any audio source into a unique sonic statement.
