Arturia Filter SEM - Analog Filtering Effect Plugin (VST/AU/AAX)

Combining simplicity with pure tone-shaping power, Filter SEM is a futuristic twist on a classic synth filter. Renowned for its pioneering technology in the 70s, it pays tribute not only to its sound but also the SEM’s reputation as a trailblazer. Using the meticulous modelling techniques, and by adding exciting new features, SEM V is a true modern classic audio filter. No longer confined to a synthesizer, you can now use the era-defining filter tone of Tom Oberheim’s cult synth module on any audio source you wish. Process acoustic instruments in your DAW, shape vocals, perform sweeps on your whole mix, create builds, rises, and drops, even use it to improve a soft-synths stock filter. Filter SEM is a must-have creative tool for any modern musician.

Simple, but stunningly effective
The original SEM, or Synthesizer Expander Module, was one of the world’s first all-in-one synth packages. Created to expand the capabilities of other synths, it could serve many purposes. Adding polyphony, fattening up their sound, and performing sequences in a supporting role to a main synth were all familiar roles for SEM.

One of the most remarkable modules on the SEM was its VCF. The 12dB per octave multi-mode filter helped define the sonic identity of Oberheim®’s popular 70s synth, because it shaped a diverse range of sounds that were almost impossible to get on other synthesizers. Filter SEM not only carefully models the crossfadable modes of the filter - low-pass, high-pass, notch and band-pass, but also expands its functionality and features to create a great-sounding, versatile filter plugin that you’ll want to use on every track you create.

Vintage tone combined with powerful contemporary features
Bringing that inimitable SEM filter tone back to life is a miracle in itself, but Arturia wanted to push the envelope. Pun intended. Able to bring another dimension to whatever audio source you choose, the story of this reworked SEM architecture started in 2012, when they released SEM V; an analog modelled, virtual emulation of the classic. Through component analysis and the advanced techniques of our TAE technology, the team was able to reproduce not only the filter, but every aspect of the original instrument in software. A hit as part of the V Collection, they couldn’t help but wonder what SEM’s filter would be capable of as a standalone plugin.

Once they isolated its VCF, they added some contemporary functionality that launch this iconic filter straight into the 21st century. Every aspect of Filter SEM, including all of the modern additions, are all controllable via MIDI CC, so should your DAW allow it, you’ll be able to control and perform using Filter SEM in your live sets, too! Speaking of the additions, take a look at what else was added to this cult synth icon:

Noise Oscillator
The effect of any filter becomes more dramatic when you add noise, so it includes a noise oscillator to let you add as little or as much as you like to your signal.

Soft clipping
The original SEM circuitry could be driven into saturation with the right settings, and SEM V makes the process even easier. Turn soft clipping on, and push the input gain, and you’ll get some sweet analog saturation.

Gate sequencer and mod sources
The new, easy to program gate sequencer lets you trigger or retrigger the envelope and LFO mod sources. This can be used to create vibrant, animated filter sequences, or subtle, undulating effects.

Simple Mod Matrix
To add a little bit of creative versatility to Filter SEM, it features a concise modulation matrix, letting you get creative and explore sound design potential never possible with the original.
