DRC⁠.

Digital Resistor Capacitor — the name is the engine.

A deep, characterful analog-modeled poly: envelopes that charge like real capacitors through resistors, a screaming dual-character filter, and a real tape echo — on a self-evolving engine that runs identically across every plugin format and every device you own.

[ OVERVIEW ]

The short version.

DRC is an 8-voice analog-modeled poly with a screaming dual-character filter, real tape echo and a self-evolving modulation core — running identically on every desktop format and every device you own.

Built around a single C++ engine that ships unchanged from VST3 on a laptop to Standalone on a phone. Patches move between platforms bit-for-bit, so the sketch you make on the train sounds exactly the same back in the studio.

01 · Character

The warmth is the circuit

Envelopes that charge through resistors, a filter that self-oscillates like hardware and a real in-loop tape echo. Analog feel as a consequence of the engine, not a label.

02 · Motion

Patches that never sit still

LFO2 frequency-modulated by LFO1, one-shot LFOs that double as envelopes, six waveforms each across 21 sync divisions — sounds that breathe, accelerate and evolve on their own.

03 · Played, not programmed

An instrument⁠, not a preset wall

Mod wheel and aftertouch each routing to seven destinations, channel + polyphonic aftertouch, full MPE for ROLI / LinnStrument / poly-AT keys, 22 scales plus tap-to-build custom.

04 · One engine, everywhere

One patch, every device

A single codebase across VST3, AU, AUv3 and Standalone on macOS, Windows, iOS and Android. NKS-native with 678 tagged presets. Build on a laptop, finish from a tablet.

[ CHARACTER ]

The warmth isn't a preset. It's the circuit⁠.

Digital
Resistor
Capacitor

That's what DRC stands for. Its envelopes charge like real capacitors through resistors; its filter behaves like a real RC network. The analog character the press singles out is a consequence of how the engine actually works.

A · Filter

Push it till it growls

A saturated 24 dB ladder and a 12 dB state-variable filter in one. Audio-rate OSC 2 FM and noise route straight into the cutoff; crank the resonance and it self-oscillates like real hardware instead of sounding sterile.

B · Tape

Real tape echo⁠, not a label

Two delay lines with a 0.48 Hz wow and 19.47 Hz flutter, plus a saturator and highpass living inside the feedback loop. Repeats warble, darken and tip into dub-style self-oscillation — and follow your playing in tune.

C · Drive

Grit that responds to touch

PreGain drives a saturation, per-voice analog detune adds organic drift, and a switchable vintage noise floor finishes the picture. The harder you push, the more it gives back.

[ MOTION ]

The synth that never sits still⁠.

DRC's second LFO is frequency-modulated by its first — one modulator continuously changing the speed of another. Add one-shot LFOs that double as envelopes, band-limited wavetables feeding a constantly- modulated resonant filter, and up to eight octaves of pitch mod, and you get patches that breathe, accelerate and evolve on their own.

  • LFO × LFOLFO2 frequency-modulated by LFO1 — motion that accelerates, decelerates and never quite repeats.
  • 2 × 6 wavesTwo LFOs, six shapes each (incl. S&H + filtered S&H), free or synced across 21 divisions, with fade-in and key/free phase.
  • One-shotFlip an LFO to one-shot and it becomes an extra envelope — more contours, no extra clutter.
  • 8 octavesPer-oscillator pitch mod from a whisper of vibrato to a full divebomb.

[ THE INSTRUMENT ]

A real synth,
not a preset wall⁠.

01 · feature

Two filters in one

A saturated 24 dB Moog-style ladder and a 12 dB Chamberlin state-variable filter — five modes in a single circuit. Seven sources hit the cutoff, including audio-rate OSC 2 FM and noise. Resonance saturates into musical self-oscillation.

02 · feature

Oscillators that stay clean

Two band-limited wavetable oscillators (SAW · SQR · TRI · SINE), a tracking sub, ring mod and hard sync. Alias-free from deep bass to the top of the keyboard.

03 · feature

Deep, expressive envelopes

Two exponential ADSRs with bipolar attack- and release-velocity. Play harder for snappier attacks — and on env 2, turn the whole contour upside-down with full invert.

04 · feature

A characterful FX chain

PreGain-driven soft-clip saturation, a true tape echo, a modulated allpass reverb and a dual-LFO chorus (ANA / DIM) — calibrated to feel like outboard, not afterthought.

05 · feature

Tunable noise & cross-mod

One BANDWIDTH knob sweeps noise from colored rumble to full white. Route it — or OSC 2 — straight into the filter for metallic, organic grit.

06 · feature

Eight voices, three characters

Poly, Mono and Unison over an 8-voice engine with smart voice-stealing and per-voice analog detune. 22 scales plus a tap-to-build custom scale, a 5-mode arpeggiator, portamento and legato.

07 · feature

Played, not programmed

Mod wheel and aftertouch each route to seven destinations at once — cutoff, resonance, LFO2 rate, vibrato, osc & filter mod, pitch. Channel + polyphonic aftertouch and full MPE for ROLI, LinnStrument and poly-AT keys.

A single codebase drives every format and platform,
with one portable patch — a desktop sound opens identically on your phone.
Formats & platforms

Four platforms⁠, one sound

Build a patch in VST3, AU or AUv3 on your laptop, then open it on iPhone, iPad or Android and hear it identically. Sketch on the train, finish in the studio, perform from a tablet.

NKS-native, 678 tagged presets

A registered Native Kontrol Standard library for Komplete Kontrol and Maschine — browse and play hundreds of tagged sounds straight from the hardware. Rare for a synth that also runs on phones.

Recorder · Android

Capture & play back in the box

On Android, a built-in recorder and sample player are first-class engine objects — capture a jam, loop it, scrub it, export it. No DAW required.

Portable patch

One identical engine

The same parameter set everywhere means the patch format itself is portable: move a sound between platforms and the engine reproduces it exactly.

Audio Plugin Guy

DRC is a unique synthesiser plugin from Imaginando that not only sounds great but has an extra special feature that makes it incredibly useful for the producer on the go.

Seriously, the ability to program a bunch of patches on the go and then use those same patches in a desktop DAW environment (and vice-versa) is a huge improvement to my music making workflow.

[ FAQ ]

Quick answers⁠.

The questions we get asked most about DRC.

What is DRC?

+
DRC is a virtual analog polyphonic synthesizer with the same sound engine on desktop and mobile — from warm pads to biting leads, shaped by its signature RC-style envelopes.

Which platforms and formats does DRC support?

+
DRC runs on macOS, Windows, iOS and Android. On desktop it's a VST, VST3 and AU plugin plus standalone; on mobile it's a standalone app, and on iOS also an AUv3 plugin.

Do my patches move between devices?

+
Yes. DRC shares one engine across every platform, so a patch made on your laptop opens unchanged in the standalone app on your phone.

Is the mobile version separate from the desktop one?

+
Yes. The desktop and mobile apps are sold separately on their respective stores; a desktop licence doesn't unlock the mobile app or vice-versa.

Can I try DRC before buying?

+
Yes. A free demo on desktop and Android lets you play the full synth first.
