One app, Four jobs

From a synth on a rack to libraries in your DAW

Get the most out of your synths and sample libraries.

Convert

Convert thousands of instrument/sample libraries at once, and rename every sample to match its program.

Auto-Sampler

Auto-sample any MIDI device or plugin, with custom set note ranges, multi-layer velocity capture, loop detection and note mapping handled for you.

Randomize

Generate unique presets for your synths via MIDI Out, with 4 different modes. Unlock the true potential of your synth.

Edit

Edit Voice/Layer (PCM), Filter, ADHSR, LFO, Step LFO, Arpeggiator and FX synth parameters directly via MIDI Out, no drivers needed.

Convert

Turn your samples into working instruments

Convert whole libraries between formats, or turn raw samples into mapped, playable instruments. Thousands in a single run, and every sample can be renamed to match its program so nothing breaks when you load it.

Built for libraries, not single files

Take whole sample/instrument libraries, and convert them to work with other software.
  • Thousands of instruments in one run — a full library in minutes
  • Rename all samples to match the name of the instrument Grand Piano C3 v2.wav
  • Twelve formats - Kontakt, MPC, SFZ, DecentSampler, Bitwig, Korg, Soundfont, Omnisphere, HISE, EXS24
  • Auto note pitch detection from filenames and audio analysis
  • A folder of samples becomes a mapped, working instrument
Auto-sampler

Capture it, layer it, ship it

A multi-sampler rig. Record hardware over MIDI or render a plugin offline, build proper multi-velocity layers, fix the loop points, keep it all organised, and save the setup for next time.
Sample hardware

Sample your favorite presets from your synths for production on the go.

Pick your MIDI port, set the key range, set velocity layers for round robin or realism, press record. It plays and records every note for you, captures the audio coming back, and names and maps each file as it goes. The keys light up as it samples so you can track the sampling progress.

  • Any MIDI device, synth or drum machine
  • Automatic note detection and mapping
  • Audition the presets live before recording
Sampling a hardware synth over MIDI
Sample a plugin

Turn any plugin into a sample library.

Load an audio plugin and sample your favorite presets, Ideal for CPU-heavy plugins.

  • Runs in its own process, so a plugin can't crash the app
  • Faster-than realtime offline rendering
  • Same mapping, layering and export as hardware capture
Sampling an audio plugin offline
Multi-layer capture

Multi-layer velocity recording

Capture several velocities per key and keep them as separate layers, so the instrument responds the way the original did instead of flattening to one dynamic. Layers can be exported as real velocity groups.

  • Multiple velocities per key across the whole key range
  • Maps as true velocity layers, not stacked oneshots
  • Rerun velocity layers if recording messes up

Loop editor

Loop point editor

Pads and strings need to hold. The loop editor finds and lets you nudge loop points so a captured note can sustain indefinitely without a click or a swell.

  • Loop-point detection with manual override
  • Visual waveform editing on the captured sample
  • Loop data written into the exported sample

Sample library

Nothing gets lost

Every completed sampler run lands in a library sorted by set, then key, then velocity. Audition any recorded sample, rerun a key that sounds off, or drop one velocity without touching the rest of the set.

  • Audition any captured sample
  • Rerun a single key that messed up when sampling
  • Delete one velocity layer without touching the other samples

The randomizer

Four different ways to roll

Real randomization, straight via MIDI & SysEx, choose what you want to randomize, per-parameter odds you control. Restrictions keep sounds usable. Generate sounds you would actually use.
Chaos mode

Generates random sound without restriction

No restriction on any parameter you leave enabled. Filter Type, Cutoff, Envelopes, LFOs, Modulation, Patchcords, Waves per layer. You choose what gets randomized. Use the parameter sliders to increase the odds of the values being randomized.

  • Genuinely random sounds but you choose how they sound
  • Per-parameter odds, put the Filter env slider to 90%, LFO rate to 80%, Samples to 100%
  • Generates presets via MIDI
Chaos
Drift mode

Change the parameters of your favorite presets

Starts from the preset already loaded on your synth and moves it by the amount you set. Perfect when the sound is right but you don't want to keep using the same preset over again.

  • The Drift % box sets exactly how far you want the preset to move away from itself
  • Keeps the character, change the details
  • Roll repeatedly to take a sound somewhere new
Drift
Basic mode

Random sounds with restrictions

Generates sounds with parameter value restrictions for creating sounds that are almost always usable.

  • Restrictions on every parameter
  • Smaller wave pool so layers sound better
  • Generates usable presets most of the time
Basic
Category mode

Choose a sound category and generate it

Choose lead, click generate, get a brand new lead sound different from whats already stock on the synth.

  • Dozens of sound categories per synth
  • A uniqueness slider to get different types of sound
  • Choose expansion cards/roms you own so you can generate more

Library & expansions

Rolls are saved to the library

Nothing gets written to your synth, all generated presets are automatically saved to the library tab. You can come back and use your generated presets at any time through the software.

  • Search for presets
  • Expansions: group presets into banks and post them to the community tab or sell them yourself
  • Import any .syx or .mid you already have for your synth

Run the randomizer in your browser

Plug your synth into your computer, open synth2software.com/studio in Chrome or Edge, grant MIDI access, and start rolling. Same engine as the desktop app, nothing to download. Free accounts get fifteen rolls a day.

Works over Web MIDI

Direct SysEx to your hardware from the browser — no bridge app, no driver. Chrome, Edge, Brave and Opera on desktop.

Your library, synced

Rolls and expansions live on your account, so the browser and the desktop app see the same sounds.

Try before you buy

Fifteen rolls a day, free, forever. Enough to hear exactly what the breeder does with your own synth before spending anything.

Questions

Before you buy

Which browsers does the web randomizer work in?
Chrome, Edge, Brave and Opera on desktop. It needs the Web MIDI API with SysEx permission, which Safari does not support — so iPhone, iPad and Safari on Mac can't run it. The desktop app has no such limitation.
Do I need the desktop app to use the browser version?
No. The browser version is standalone — connect your synth by USB or a MIDI interface, allow MIDI access when prompted, and roll. The desktop app adds the auto-sampler and the format hub, which need local file access.
What counts as one randomization on the free plan?
One roll — one press of Randomize or Generate that sends a new patch to your synth. Editing parameters afterwards is unlimited and free. The counter resets at midnight UTC.
Will it damage or overwrite my synth's patches?
No. Rolls are written to the temporary patch area, which is what your synth loads a sound into when you select it. Nothing is committed to memory unless you press Save on the unit yourself.
My synth isn't listed. Will you add it?
More synths will be added in future updates.
Is the Randomizer Plugin included with the Desktop Suite?
It's a separate add-on. The Desktop Suite is the standalone application; the Randomizer Plugin runs the randomizer inside your DAW and replaces its MIDI-Out plug-in.
Refunds?
The free plan exists so you can confirm it works with your exact hardware before paying. All sales are final.
