Independent audio tools

Good sound.
Hard character.

Familiar hands-on controls. A little attitude in the signal path. We’re building audio plugins for the way you actually mix.

First on the bench / 001

The 609.

Our first plugin, and the one furthest along. What you see below is the real development build, running test tones with scripted control automation.

Stereo compressor / limiter

Inspired by the Neve 33609

609

  • Separate compressor and limiter sections
  • Stereo link or dual mono
  • Stepped and auto recovery
  • Live gain-reduction meters
In development
Approved 609 hardware layout design
Approved hardware design · scripted controls and lights · native skin integration in progress

Hardware design target. Plugin builds currently use the earlier skin.

Also on the bench

The next circuits.

R7 and PRESSURE now have working native interfaces. The Big 25 and Silky previews remain design concepts while their engines take shape.

The Big 25

Download Windows/macOS test build

Stereo bus compressor

Inspired by the API 2500

In build
Approved Big 25 hardware design preview with scalloped knobs and amber meters

Hardware design preview · scripted motion. This is the visual target for the plugin.

No release dates yet. We’d rather get the sound right than hit a calendar.

WindowsVST3

For VST3-compatible DAWs.

macOSAU + VST3

Universal builds for Intel and Apple silicon.

LaterAAX

Pro Tools support is planned for later.

Console family · in development

A desk of your own.

Channel E

A tactile console strip with filters, four-band EQ, compression and gate/expansion. Red DRIVE for harmonic color. Blue OUTPUT for clean level.

Channel E stereo design study: dedicated CROSSTALK knob, red DRIVE, blue OUTPUT and TALK GROUP A

Stereo study: two audio meter columns. View mono study with one audio meter. No mixer fader.

Bus G

Download Windows/macOS test build

The companion stereo bus compressor. A large gain-reduction meter, a SIDECHAIN HPF that reduces bass triggering without cutting bass from the audio, and Auto Fade with a separate RATE control from 1–60 seconds.

Approved horizontal Bus G hardware design study

Hardware design preview · scripted motion. Native artwork integration is pending.

Original compressor core passed Windows/macOS checks; native Windows/macOS adapter checks, Windows VST3 pluginval and macOS Audio Unit validation passed. Listening qualification remains in development.

Optional companion · in development

Crosstalk

Download the Windows/macOS explicit-routing prototype · GitHub sign-in required for this private development repository.

40 channels on one page. Named groups such as Drums show Kick, Snare, Toms and overheads. Receive faders control incoming bleed, not track volume. Filter by group or see the whole desk.

Interactive layout study only. All 40 controls share one page; narrow screens scroll horizontally. Example names and connections are not real DAW discovery. Additional sessions would use pages of up to 40; host integration and CPU validation remain unfinished.

Channel E works on its own. The planned companion plugin connects routed channels so real audio can bleed between them—without injected hiss. TALK GROUP chooses which channels interact; the strip’s CROSSTALK knob controls incoming bleed. DRIVE adds harmonic color; OUTPUT adjusts level cleanly.

The 40-lane grouped core and explicit-routing Windows/macOS hub prototype have passed automated checks. Automatic companion-to-strip routing is not finished. The intended strip control shows OFFLINE until connected; these images illustrate the connected layout. Low CPU use is a design requirement; performance figures will follow measured builds.

Channel E is a scripted design study. Bus G and The Big 25 lead with their hardware design previews; unapproved native test skins stay in the development repository. Final artwork and listening qualification remain in development.
