What it does

Oxid is the developer's "close simulation" of the ARP Omni-2, a late-70s polyphonic string machine with an added synthesizer section. It pairs the ensemble strings with a paraphonic synth voice, which the developer calls "paraphonic madness".

String section: 8' and 4' registers for the main strings, plus a separate 8' and 16' bass section for low voicings.
Synthesizer section: a paraphonic synth voice that can be layered with the strings.
Filter and envelopes: a resonant lowpass filter with an ADSR envelope, and an AR amplitude envelope.
Modulation and panning: an LFO, plus separate panning for the string and bass voicings.
Effects: a BBD-style chorus, a phaser and a delay, as described by Bedroom Producers Blog; the product page lists the phaser and delay.
Polyphony and sounds: 64 voices and factory programs by Kraftraum.
Control and UI: MIDI Learn for every parameter and a resizable UI in the ARP orange, white and black colour scheme.

The current version is 1.0.4 (11 Feb 2026). It is a free download with no price listed; the developer accepts donations. English and French PDF manuals are available.

When to use it

Oxid is the better pick when you want one specific sound: a phased 70s ARP string ensemble, with bass and synth layers under it, for free. Compared with Omnisphere 3 and Pigments 7 it has a tiny fraction of the sound-design range, but every control maps to one instrument and the classic string pad is there in seconds. Compared with CS-80 V, which is a fully polyphonic synth often used for brass and strings, Oxid is simpler and more fixed in character, with a paraphonic synth section rather than full per-voice shaping. Its built-in phaser and chorus cover the classic string-machine treatment without extra plugins.

Best for: vintage string pads, phased ensembles, string-and-bass layers and 70s-style synth beds.
Genres: electronic, ambient, disco, synth-pop and soundtrack work.
Look elsewhere if: you want realistic orchestral strings or a general-purpose synth; Omnisphere 3 or Pigments 7 cover far more ground.

What producers say

Early feedback is warm, though there are only a few user reviews so far.

KVR users rate it 5 out of 5 from 1 review, praising the sound, the paraphonic synth and the GUI with its built-in keyboard.
Bedroom Producers Blog called it "a splendid addition" to the developer's range and praised the phaser and delay with the string sounds.
