The heritage

The sound of five machines.
In one plugin.

Inspired by the machines that made stereo history. From tape double-tracking and analog chorus to early digital pitch shifting.

    The rack preset behind every huge guitar and lead vocal of its era.

Mix-safe

Wide.
Never weak.

The old racks ate the center and smeared the hits. This one doesn’t.

  • Center Keep

    Width goes to the sides. Your vocal stays put.

  • Transient Keep

    Hits land dry and punchy. The tail blooms wide.

  • Safe

    Watches phase and holds the mix together in mono.

  • Bass Mono

    The low end stays centered and solid.

Plug in the rack.

Questions.

When will STEREOMACHINE be available?

STEREOMACHINE launches on October 27, 2026. Click Buy and leave your email to receive a launch notification. No payment is taken.

Is it an emulation of the original units?

STEREOMACHINE uses original algorithms inspired by classic tape double-tracking, analog chorus and digital pitch shifting. These are interpretations with modern controls, not exact circuit recreations. Pure Width is our own stereo-widening algorithm.

Will it fall apart in mono?

No. Pure Width keeps the mono sum clean by design, and every mode has Safe, Center Keep and low-end control.

Can I use it on the master?

Yes. Pure Width with Bass Mono is made for the mix bus and the master.

Which formats?

VST3 and AU, plus a standalone app.
