01Overview

Filter SEM brings the state variable filter of the Oberheim SEM, a module originally made to expand other synthesizers, into a DAW as an audio effect. Arturia modeled the filter and added a noise oscillator, soft clipping, a gate sequencer that triggers the envelope and LFO, and a compact modulation matrix. It can be used on acoustic instruments, vocals, drum buses or whole mixes, not only on synth tracks.

Filter character and modes

The filter is a virtual recreation of the classic 12dB per octave SEM state variable design. Its low-pass, high-pass, notch and band-pass modes can be crossfaded, which makes it possible to move smoothly between filter types rather than switching between them.

Mode, cutoff frequency and resonance controls shape the tone, while a dry/wet setting and a filter output volume control let you blend the effect into the signal. Arturia also notes that soft clipping can add analog-style saturation when the input gain is pushed.

Modulation, sequencing and workflow

The low frequency oscillator offers five waveforms plus a sample and hold mode and can sync to the DAW clock. The gate sequencer has up to 16 steps and can trigger or retrigger the envelope and LFO to create rhythmic filter movement.

The modulation matrix uses the envelope and LFO as sources with eight destinations. Every parameter, including the added features, is controllable via MIDI CC, so filter moves can be performed in live sets if the host supports it.
