Filter SEM

Arturia Filter SEM brings the distinctive tone of Tom Oberheim’s classic Synthesizer Expander Module to an audio effect for your DAW. Modelled on the original 12 dB-per-octave multimode filter, it offers low-pass, high-pass, notch and band-pass filtering, with crossfadable modes for exploring different tonal shapes. Use it to soften bright percussion, trim low-end rumble from vocals, reshape acoustic recordings or give a software synth a different filter character. It also lends itself to sweeping transitions across a full mix, helping you build tension and movement in electronic arrangements. Rather than keeping that celebrated ’70s filter sound inside a synthesizer, Filter SEM makes it available for any audio source. Its straightforward approach suits hobby producers and experienced musicians who want expressive tone shaping without an overly complicated workflow.
