A SYNTHESIZER WITH A STUDIO INSIDE

Start from nothing.
End with everything.

BlankSlate is a four-oscillator analogue-character instrument with a visual signal-flow view, a 16-slot patch-bay modulation matrix, and an entire rack of console-grade outboard — preamp, EQ, compressor, tube, and tape — wired into every voice. One plugin. The whole signal path.

ONE INSTRUMENT, THREE WORKSPACES

However you think, BlankSlate keeps up.

Most synths bury their depth behind tabs and menus. BlankSlate gives you three full-screen ways to work the same engine — tweak it like a console, read its signal flow at a glance, or patch its modulation like a matrix. Switch instantly; nothing is ever more than one click away.

Every oscillator, filter, envelope, and outboard stage laid out at once on a brushed-metal console — hands-on, immediate, nothing hidden. This is where sounds get dialled in.

Patch anything to anything

A true patch-bay matrix: drag a cable from any source to any destination, drag up or down to set depth. LFOs, chaos, envelopes, velocity, macros — all routable, all at a glance.

THE SOUND ENGINE

Four oscillators that breathe.

Two character engines per voice — switch any oscillator between FM for metallic, glassy, bell-like motion and Analogue for fat, drifting classic waves. Then make them imperfect on purpose.

OSC 1–4 · dual-engine voices

Each oscillator carries its own tuning (Octave / Semitone / Fine), level, and stereo pan, plus two analogue-soul controls that separate BlankSlate from sterile digital synths:

  • Shape — continuously morph the waveform, from hollow to harmonically rich.
  • Drift — per-voice analogue pitch instability that keeps stacked oscillators alive and never phase-locked.
  • FM ↔ Analogue — a per-oscillator engine switch, so one patch can blend digital edge with vintage warmth.
  • Unison & spread — stack voices wide with detune and stereo spread from the global shelf.

Comb FM · the secret weapon

A dedicated comb-resonator and cross-FM section sits beside the oscillators — feed oscillators into one another (FM 1→2, FM 2→1), tune the comb, and push feedback for everything from plucked strings and vocal formants to screaming metallic resonance.

  • Mix · Feedback · Tune — sculpt the resonant body of the sound.
  • Cross-FM matrix — route oscillators into each other for inharmonic, evolving timbres.
The Comb FM section.
DUAL FILTERS

Two filters. Series or parallel. Both with teeth.

A Ladder filter for that creamy, saturating low-pass thump, and a versatile State-Variable filter you can run in series or parallel with it — each with its own drive, key-tracking and envelope depth.

Filter 1 · Ladder  ·  Filter 2 · SVF

  • Ladder (12/24 dB) — the classic four-pole sound, with a built-in Drive stage that turns resonance into grit and growl.
  • State-Variable — low / high / band / notch response, switchable and modulatable on the fly.
  • Series or Parallel — chain the two filters or split them across the stereo field for complex, vocal-like sweeps.
  • Cutoff · Reso · Drive · Key · Env — full per-filter control, every knob automatable.

MODULATION THAT NEVER SITS STILL

Three LFOs. Three envelopes. And chaos.

BlankSlate doesn't just modulate — it evolves. Beyond the expected LFOs and envelopes, two Chaos generators run on strange-attractor math (Lorenz) for organic, never-repeating movement you can't get from a sine.

The 16-slot patch-bay matrix

Open the Mod view and the whole modulation engine becomes a patch bay. Drag a cable from any source on the left to any destination on the right; drag the cable up or down to dial depth. No menus, no hunting.

  • Sources — Env 1–3, LFO 1–3, Chaos 1–2, Velocity, Key, Aftertouch, Mod Wheel, four assignable Macros, plus Random & Sample-and-Hold.
  • Destinations — oscillator pitch / level / shape, filter cutoff & resonance, amp, LFO rates, and more.
  • Macros — collapse a dozen moves into one knob for expressive, performance-ready patches.

Envelopes & LFOs with intent

Three dedicated DAHDSR-style envelopes are pre-wired to Amp, Filter and Aux, so you're making sound in seconds — then free to repatch them anywhere. Three LFOs offer classic shapes through to Lorenz chaos, free-running or tempo-synced.

  • Env 1–3 — Amp / Filter / Aux, fully shapeable.
  • LFO 1–3 — multiple shapes, free or synced, with per-LFO rate & depth.
  • Chaos 1–2 — strange-attractor modulation for living, breathing texture.

THE STUDIO IS BUILT IN

Every voice runs through a real console chain.

This is what makes BlankSlate sound finished, not flat. Before a note ever leaves the plugin, it passes through analogue-modelled outboard most producers reach for after the synth — preamp, EQ, compressor, tube and tape, all in the box, all automatable.

Transformer Preamp

Ironheart

A console-style input stage modelled on classic transformer preamps. Drive for harmonic thickness, Colour to dial the transformer character, Out to set level. It's the glue that makes the rawest oscillator sound expensive.

Class-A Equaliser

Contour

A musical, stepped EQ in the spirit of the great British consoles. Sweet high shelf, punchy proportional-Q mids, a fat low band and a switchable HPF — broad, confident moves that always sit right in a mix.

FET Compressor

Vicegrip

A lightning-fast FET compressor with attitude — from gentle 4:1 glue all the way to its all-buttons-in Nuke mode. Built-in Dist adds the aggressive harmonic bite that made the original a legend.

SATURATION BY DESIGN

The harder you play it, the dirtier it gets.

BlankSlate is not a clean digital synth — it's a saturating analogue console you play from a keyboard. Hold one note and it's warm and round. Stack a fat gospel chord and dig in, and the whole front end leans into it: the transformer blooms, the valves overdrive, the harmonics pile up into thick, gritty, soulful drive. That dirt isn't a bug — it's the entire character of the instrument.

Why it does that — the signal chain

Most synths send each note straight out. BlankSlate doesn't: every voice you play is summed and pushed through a full analogue console chain before it ever reaches your ears. A single note nudges those stages gently. A six-note chord hits them far harder — so saturation, compression and harmonic intermodulation all grow with the chord. More notes, more weight, more dirt.

  • Ironheart transformer preamp — the input stage every voice hits first; the hotter the signal, the more low-order harmonic thickness it adds.
  • Vicegrip FET compressor — clamps the louder chord and pushes it into its fast, aggressive, harmonically-rich character.
  • Dual valve stage — modelled 12AX7 + EL34 tubes that overdrive progressively as the level climbs.
  • Tape — wow, flutter and tape compression smear it all into vintage glue.

Every note, every chord — the same path. That's why it sounds like a record, and why it bites when you lean on it.

CLEAN

One button. Twice the instrument.

Hit CLEAN and the entire console chain drops out in a single click — preamp, EQ, compressor, valves, tape, the whole path — straight-wired to the pure, dry, untouched synth voice underneath. Suddenly every preset is two: the saturated, record-ready console version, and its clean, crystalline twin. 584 factory sounds become 1,168 — the same patch, two completely different personalities, one button apart.

Clean to filthy on one knob

You're always in control of the dirt. Single notes stay warm and present, and BlankSlate is voiced so dense chords stay musical rather than fizzy. Want delicate, pristine worship voicings? Back off the drive. Want full Detroit-gospel grit? Lean on the Magic macro and push the whole chain — preamp, valves, tape — into glorious overdrive. The character is yours to dial.

  • Warm, not harsh — polyphony-aware voicing keeps big chords thick instead of harsh.
  • Magic macro — one knob that ramps the entire saturation chain from clean to filthy.

TUBE · TAPE · SPACE

Saturation, motion, and dimension.

The back end of the chain is pure vibe. A dual-tube stage, real tape wow & flutter, and a trio of studio effects turn a static patch into a recording.

Tube Stage & Tape

Push the signal through modelled 12AX7 and EL34 valves with independent drive, bias and tone, in series or parallel — soft warmth to full overdrive. Then add Wow and Flutter for the gentle pitch-instability of analogue tape.

  • Dual valves — 12AX7 + EL34 with Drive 1/2, Bias 1/2, Tone & Makeup.
  • Tape — Wow & Flutter for authentic, organic detune.

Chorus · Delay · Reverb · Master

A lush Chorus, a tempo-syncable Delay, and a deep Reverb give every patch its space — followed by a transparent Master stage with a brick-wall ceiling so your sounds arrive loud, clean and finished.

  • Chorus — Rate / Depth / Mix.
  • Delay — Time / Feedback / Mix, free or synced.
  • Reverb — Size / Damp / Mix.
  • Master — output level with a safety ceiling/limiter.
