The hype is real (and so are the features)

Ridiculously over-equipped

We packed SynSyn 1000 with so much sound it technically counts as a weather system. Every feature below is genuinely in the box.

Three-oscillator thunder

Three oscillators with Sine, Saw, Square, Triangle and Noise, each with level, coarse (±24 st) and fine (±100 ct). Anti-aliased PolyBLEP saws and squares, so your highs stay squeaky clean.

16-voice polyphony

Sixteen voices with note stealing, a velocity-sensitive ADSR amp envelope and pitch bend. Mash every key you own. SynSyn can take it.

Screaming resonant filter

Per-voice state-variable filter in low-pass, high-pass and band-pass, 20 Hz to 20 kHz, resonance up to Q 20 and always stable, key tracking and its own ADSR with ±7 octaves of envelope amount.

Two wobble-tastic LFOs

Sine, triangle, saw up, saw down, square and sample & hold, 0.01–40 Hz or tempo-synced from 4/1 to 1/32 (dotted and triplet too). Route to cutoff, resonance, pitch, oscillator levels or amp. Mod-wheel vibrato included.

Built-in sparkle chain

Chorus, then delay (ping-pong, tempo sync, high-cut, up to 4 s), then reverb with pre-delay. Zero added latency, and zero CPU when an effect is off.

Presets, glitch-free

24 factory presets plus your own user presets, saved as readable files. Switching presets fades smoothly over 10 ms, so no clicks and no stuck notes. Ever. Basically magic.

VST 3 + LV2 + Standalone

One download, three ways to party: a VST 3 plug-in, an LV2 plug-in and a standalone app. Every parameter is host-automatable.

Speaker-safe by design

An output safety limiter keeps everything under 0 dBFS with a −1 dBFS ceiling, even with all 16 voices at +6 dB. Go wild responsibly.

Headline feature

No DAW? No problem.

The SynSyn 1000 Standalone app is the whole synth in its own window. Launch it, plug in a keyboard, play. That's it. That's the tweet.

  • Runs without any DAW. Just start the app from the download and you're making noise.
  • USB MIDI auto-connect. Every available MIDI input is switched on at startup.
  • Hot-plug friendly. Plug a keyboard in mid-session and it's picked up; unplug and re-plug and it comes right back.
  • Your choices stick. Untick a device in Options › Audio/MIDI Settings and SynSyn remembers it.
  • MIDI light in the title bar. Steady red when a MIDI input is connected, with a bright flash on every note. MIDI
Get the Standalone

The Standalone ships inside the same Linux download as the plug-ins.

System notes

  • 64-bit Linux (x86_64) with glibc 2.38 or newer, for example Ubuntu 24.04 or later.
  • Needs fontconfig and FreeType (installed on most desktops); the Standalone also uses ALSA (libasound) for audio and MIDI.
  • Check your download: sha256sum synsyn-1000-0.6.1-linux-x86_64.tar.gz should print the SHA-256 above.

Install in four steps

  1. Unpack into its own folder

    The archive unpacks into the current folder, so give it a fresh one.

    mkdir synsyn-1000
tar -xzf synsyn-1000-0.6.1-linux-x86_64.tar.gz -C synsyn-1000
cd synsyn-1000

  2. Install the VST 3 plug-in

    mkdir -p ~/.vst3
cp -r "VST3/SynSyn 1000.vst3" ~/.vst3/

  3. Install the LV2 plug-in

    mkdir -p ~/.lv2
cp -r "LV2/SynSyn 1000.lv2" ~/.lv2/

    Then rescan plug-ins in your DAW.

  4. Run the Standalone

    chmod +x "Standalone/SynSyn 1000"
"./Standalone/SynSyn 1000"

    Plug in your USB MIDI keyboard and the MIDI light turns red. If a keyboard plays double notes, untick the duplicate input in Options › Audio/MIDI Settings.
