Most MPE-capable plugins announce themselves loudly. They arrive with morph pads, multi-engine architectures and marketing copy about "multidimensional expression". Audio Damage's newest instrument does the opposite: AD-202 looks like a small grey box from 1982, has one oscillator, one envelope and one LFO — and happens to accept per-note pitch bend, pressure and slide.

That combination is more interesting than it sounds.

What It Actually Is

AD-202 is Audio Damage's take on the Roland MC-202, the sequencer-plus-synth that has spent four decades being overshadowed by its TB-303 sibling. The signal path is deliberately minimal: a single VCO offering saw, pulse, sub and noise, running into a 24 dB ladder filter, with one envelope and one tempo-syncable LFO with delayed onset.

Underneath the vintage panel, though, the instrument is thoroughly modern. It runs mono or eight-voice polyphonic, adds per-voice analog drift, includes MTS-ESP microtuning support, and finishes with a post-VCA colour section offering pre-filter saturation, filter drive, distortion and a tilt EQ. And it supports MPE.

The plugin is available for macOS, Windows and Linux in VST3, AU, AAX and CLAP formats at an intro price of $39 until September 15, 2026 (regular price $49), with an AUv3 iPhone and iPad version on the App Store at $4.99. Audio Damage continues its long-standing policy of no subscription, no DRM and no dongle, with a perpetual licence installable on every machine you own. The manual is public if you want to read the architecture before buying.

Why a One-Oscillator Synth Is Worth an MPE Player's Attention

There is a persistent assumption in the MPE world that expressive playing needs a large instrument behind it — a physical modelling engine, a granular layer, a modulation matrix with forty destinations. Osmose owners in particular tend to reach for the biggest patch available.

But a simple synth responds to expression more legibly than a complex one. With a single oscillator and one filter, every millimetre of finger pressure maps to something you can actually hear and predict. There is no interaction between six modulation sources muddying the result. When you press harder and the filter opens, you know exactly why.

That legibility is genuinely useful when you are learning a new controller. Players coming from a weighted keyboard to a LinnStrument, Osmose or Striso board usually struggle less with pitch and more with calibrating pressure. A one-VCO synth gives immediate, unambiguous feedback on that calibration in a way that a lush evolving pad simply cannot.

The Practical Caveats

Audio Damage has not published a detailed breakdown of AD-202's MPE routing, and the architecture sets natural limits on it. With one envelope, one LFO and a small set of destinations, the useful expression targets are essentially filter cutoff, amplitude and pitch. Do not expect a per-note modulation matrix.

Two things are worth verifying on your own system before building anything around it:

Neither is a dealbreaker. Both are the sort of thing worth ten minutes of testing during a demo period rather than discovering mid-performance.

Where It Fits

AD-202 is not going to replace a flagship MPE instrument, and it is not trying to. What it offers is a cheap, light, well-behaved synth that happens to respond to per-note data — useful as a bass voice under an expressive lead, as a practice instrument while learning a controller's pressure curve, or simply as a plugin that opens instantly and does one thing well.

The iPad version deserves a mention of its own. At $4.99, paired with an MPE controller over USB-C, it turns a tablet into a perfectly viable expressive monosynth rig for the price of a coffee.

The intro pricing ends September 15. If you have been curious whether stripped-back synthesis suits your MPE playing, this is an unusually low-risk way to find out.
