Studio
high-gain.
No hardware.

Plug in a guitar, get a studio-grade high-gain tone out of your speakers. Then rewire the entire signal path like a patch bay. The panel beside this text is the actual engine, compiled to WebAssembly: press play, load a rig, delete nodes and drag new wires while the loop keeps playing.

Phase-True Parallel

Mix anything
with anything.

Parallel paths are where the big tones live, and where they usually fall apart. Blend two cabinets, stack a dry path, split into delay and reverb lanes, and the moment two signals meet out of time or out of polarity, the low end hollows into mud and comb-filter fizz. Crosswire aligns every merge automatically, timing and polarity both, so stacked paths only ever add.

OFF: the classic hollow parallel blend

ON: same rig, phase-true

Same riff, same amp, same two cabinets. One impulse response arrives 1.1 ms late and polarity-flipped, the everyday parallel accident. Both clips rendered by the actual Crosswire engine and loudness-matched; only Align Lanes differs.

Mud-free stackingEvery merge is corrected for timing and polarity skew before it can thin your tone.

Any IR, any packMismatched captures stop cancelling each other, so you can blend cabinets freely.

Always on, zero costNo added latency, and re-alignment is click-free even mid-take.

The Randomizer

Infinite tones.
One button.

Hit Randomize and Crosswire builds a complete rig on the spot: amp, cabinet, effects and the wiring between them, ready to play. Audition rigs until one grabs you, then tweak every knob, swap every cable, until it sounds exactly like you. Nothing is locked. Every roll is a starting point you can rewire.

Every roll is a working rig. Sensible pairings, never a broken patch or a dead end.
Keep the magic, re-roll the rest. Pin the nodes you love and randomize around them, or re-roll just the ones you don't.
Free-form rolls go further. Parallel lanes, dual delays and split paths you'd never think to patch by hand.

Your signal path

Any effect. Any order. Any path.

Put drive before the amp, modulation after it, or split the sound into parallel delay and reverb paths before bringing it back together. The whole path works like a patch bay: any node, any order, rewired live.

Rigs that listen

Some nodes hear you.
The rig follows.

A few nodes analyze instead of processing. BEAT finds your tempo and taps out the hits inside a chosen frequency band. CHORD latches whatever you strum. ENV rides your pick attack. Wire their outputs into drums, oscillators and effect knobs, and the patch starts reacting to how you play.

A wide tonal range

Nineteen amps.
Thirty-nine cabs.

Move from sparkling cleans and vintage breakup to tight modern gain without buying another pack. Pair any amp with any cabinet, then shape it with the same open routing used by the rest of the patch.

19 distinct amp voicings across clean, crunch and high-gain families.
7 immediate cabinet voices plus 32 convolution cabinet choices.
EQ, compression, drive, modulation, pitch, rotary, looping and more.

Built for ears that notice

Responsive when you play.
Quiet when you work.

Under every patch is a small real-time engine with strict rules. These are the four that decide how Crosswire behaves on a gig, and the numbers they produce.

The audio thread
owns nothing

Once sound is running, the render loop never allocates memory and never waits on a lock. Every audio block is plain arithmetic on buffers prepared in advance. That discipline is why patch edits, preset changes and effect toggles stay click-free while the signal is live, and why a four-hour set behaves like the first five minutes.

Every path
knows its latency

The graph carries a sample-exact delay figure down every branch. Where parallel lanes meet, the engine lines them up in time and polarity before the mix, so stacked cabinets and wet/dry splits reinforce instead of comb-filtering. The convolution cabinet stage adds zero samples of its own on top.

A rig
is a number

Any patch collapses to a Rig Seed, and a seed rebuilds its rig exactly: wiring, knob values, amp and cabinet choices. The same engine also renders offline from the command line, which is how we fingerprint and regression-test every factory rig before it ships. A tone you can print twice is a tone you can trust.

One engine,
every shell

The standalone app, the VST3 and CLAP plugins, the terminal interface and the offline reamp tool share one DSP core. A Rig Seed recalls the same rig, with the same sound, in each of them. Nothing here is a port of the "real" version.
