SILVERPLATTER AUDIO PRESENTS

Your sound library
is the synth.

SPASynth is a hybrid synthesizer built around the entire Silverplatter Audio sound-effects library (88 packs, 11,401 production-ready sounds), playable as oscillators, granular fuel, and modulation sources inside a full wavetable synth with an organic-chaos engine and a one-button patch randomizer.

THE HOOK

Other synths give you waveforms.
This one gives you the whole Foley stage.

A typewriter. A rainstorm. A billiard break. Load any of the 11,401 sounds in the library and it becomes a playable keyboard instrument, a granular cloud, or the modulation source that pumps your filter, all at once, if you want.

ANY SOUND rain · typewriter · billiards · 11,401 more
OSC Oscillator Keytracked, root note, start offset, loop points
GRAIN Granular Fuel Size, density, position, spray, scrubbed by an LFO
MOD Modulation Source SFX Amp + SFX Pitch, analyzed on import

Every loaded sound is analyzed the moment it loads: amplitude follower and pitch tracking, automatically. Route a thunderstorm's loudness to your filter cutoff and the storm plays the synth.

PATCH GENERATION

One button. A genuine patch generator, not a gimmick.

RANDOMIZE ALL rolls an entire playable patch. The WILD knob sets how polite or unhinged the results get. Every parameter carries hand-tuned, musically weighted randomization ranges and biases. Every roll is guaranteed to make sound.

Lock what you love, re-roll the rest:

WILD

ORGANIC CHAOS

Analog instability, on purpose.

A bank of slow random walkers drifts pitch, phase, wavetable position, and amplitude per voice, plus drifting saturation and distortion for harmonic movement. Global depth, rate, and mix, all modulatable. It's what makes digital patches breathe.

THE FULL PICTURE

Everything under the hood.

ENGINES

7 engines, 3 slots

Wavetable, Sample/SFX, Granular, Virtual Analog, 2-op FM, Noise (white/pink/brown), and Karplus-Strong Pluck. Mix and match across three oscillator slots.

FILTERS

Dual multimode filters

Two filters, 8 types each (LP/HP/BP/Notch, 12 & 24 dB), drive, keytracking, ±4 octave envelope depth, and dry/wet mix. Route them series or parallel.

MODULATION

16-slot mod matrix

20 sources (3 envelopes, 3 LFOs, macros, velocity, mod wheel, aftertouch, chaos, and 6 SFX followers) into 90+ destinations. Evaluated at 64-sample resolution.

ARP

12-mode arpeggiator

Up, down, up/down, converge, diverge, chord, random-walk, and melodic phrases. Plus CHANCE, STUTTER, JUMP, and HUMAN probability controls that turn patterns into performances.

PLAY

Built to play live

Global glide across every engine and both filters' keytracking, 16-voice polyphony, and MIDI Learn on every single control: right-click, move a knob, done.

FX

Full effects chain

Distortion, chorus, tempo-synced ping-pong delay, reverb, and a 3-band EQ, each with its own live, signal-fed scope.

LIBRARY

88 packs, 11,401 sounds

24-bit/48kHz, production-ready for film and TV. Auto-discovery means you extract to one folder and SPASynth finds it, no scanning dialogs. 264 factory presets included.

INTERFACE

Telemetry-animated UI

A resizable, GPU-friendly vector interface where every scope, envelope, LFO, and filter curve is animated live from the actual audio engine. Re-tint every accent color to your own palette.

MAKE IT YOURS

Two accent colors. Any colors you want.

The default theme runs deep blue-teal with orange for audio and cyan for modulation. A built-in picker re-tints the entire interface: link both accents for a single-color look, or split them however you like.

EDITIONS

Same synth. The difference is the library.

Pricing coming soon.

Standard

The full synth

  • All 264 factory presets
  • 440-sound starter library (5 sounds from every one of the 88 packs)
FULL LIBRARY

Standard → Pro: pay the difference, download the full library, drop it in the same folder. No reinstall, nothing to activate. Individual add-on packs install the same way. Every copy can carry a personal ownership stamp ("Licensed to you@…") shown in the footer. A signature, not a lock.

THE POSITION

SPASynth has no copy protection, no serial numbers, no activation, no dongles, and it never phones home. We sell to people who pay for the tools they love, and we price it accordingly. The license is simple: use the sounds in anything you make, royalty-free, forever: just don't redistribute the raw files.

FAQ

Good questions.

Will my DAW support it?

On macOS, SPASynth ships as AU and VST3, plus a standalone app. On Windows, it's VST3 and standalone. If your DAW hosts either format, you're set.

Do I need the library on my system drive?

No. Point SPASynth at the library folder wherever it lives: external drive, NAS, wherever. Auto-discovery finds it, and presets use portable paths so sessions survive the library living anywhere.

What happens when I upgrade to Pro?

Pay the difference, download the complete 11,401-sound library, drop it in the same folder as your Standard library. No reinstall, nothing to activate.

Is there copy protection?

No. No serial numbers, no activation, no dongles, no phone-home, ever. Buy it, download it, own it.

Pro Tools / AAX support?

Not in v1.
