01

Magnetic Physics

True mathematical emulation of tape transport. Control wow, flutter, oxide age, stick-slip (stiction), and dynamic frequency curves from 1" Master to Cassette.

Integrated Rack

Load the GCS A-10 Poly Synth, Voxtone Rhythm Machine, MonoBass, or Glissandio directly into the session. Route MIDI and audio natively without external hosting.

03

Analog Outboard

Process channels through component-modeled effects: LA-2A Opto Compressor, FET-76, Tape Echo, Spring Reverb, Parametric EQ, and Multi-Modulation.

04

Hardware Workflow

Punch-in with zero-latency monitoring, layer infinitely via Sound-On-Sound, bounce tracks internally, and link channels with VCA grouping.

05

Dual Interface

Operate in the skeuomorphic vintage console view, or switch to the distraction-free Minimal UI featuring configurable Light and Dark modes.

06

Session Resilience

Engineered for stability. Every fader movement and tracking edit is protected by background auto-saving and robust crash recovery systems.
