What it does

Cassette644 is HoRNet's emulation of a vintage 4-track cassette recorder, the kind of portastudio machine behind many home-recorded demos. Rather than a wobble effect, it models the recorder as a whole: the tape stage plus the channel EQ, with the idea of building a "virtual cassette multitrack" across a session.

Tape types: Type I (Normal), Type II (Chrome) and Type IV (Metal), each with a distinct sound.
Tape speed: slow or fast, each with its own sonic character.
EQ: a three-band semi-parametric EQ with gain and frequency controls.
Routing: run EQ into cassette or cassette into EQ, and switch either module on or off.
Hiss: hiss emulation for both the EQ and the cassette modules, each switchable.
Link: a Link switch syncs settings across instances, so every track in a session goes through the same virtual machine.
Metering and gain: VU meters for input and output, with linked input and output gain to keep the overall level constant while you drive the tape.
Quality and GUI: up to 4x oversampling with automatic settings, a sharp vector interface and light and dark modes.

The current version is 1.0.3. The demo silences now and then, doesn't save settings and doesn't respond to host automation.

When to use it

Cassette644 is the pick when you want the coloration of a home 4-track recorder across a whole session at a very low price. Compared with RC-20 Retro Color or SketchCassette II, it offers little in the way of wow, flutter, dropouts and degradation; instead it focuses on tape type, speed and the channel EQ, which suits subtle recorder colour on many tracks. Its Link switch keeps every instance on the same settings, so it works as a session-wide tape stage rather than a single-track effect. Next to the Ampex ATR-102, it is a much cheaper, rougher consumer-tape flavour rather than a studio mastering machine. For heavy saturation and drive, Decapitator goes much further.

Best for: warm, slightly dulled lo-fi colour on drums, keys, guitars and vocals, or on every track of a demo-style mix.
Genres: lo-fi, indie, bedroom pop, hip-hop and singer-songwriter.
Look elsewhere if: you want obvious wobble, noise and dropouts (RC-20 Retro Color or SketchCassette II), or clean studio tape for the mix bus (Ampex ATR-102).
Tip: as HoRNet suggests, turn on Link and use an instance on every track to build a virtual 4-track; the linked input/output gain lets you drive the tape without changing the mix level.
