What It Is

Sine Machine is an additive synthesizer software instrument on Melatonin.dev, created by independent developer Sudara. It runs on macOS and Windows, supports VST3, AU, and CLAP plugin formats, and can also be used as a standalone app. Rather than targeting general-purpose sampling or traditional subtractive synthesis, it is a sound design tool built around large numbers of sine waves, harmonics, and visual control.

Core Capabilities

Its technical highlights include more than 10,000 time-domain oscillators and over 20,000 LFOs. A single architecture provides 20 voices, with 511 time-domain oscillators per voice. Users can batch-edit per-harmonic ADSR, volume, and pitch LFOs, and use additive “reverb” made from 1,000 sine waves, as well as additive “filters” such as brickwall and gaussian band-pass. It also supports per-harmonic gaussian pitch noise, plain-text JSON presets, and a highly visual interface, making it well suited to creators who want to understand and shape complex harmonic structures.

Pricing and Licensing

The product is currently in Early Access. The page lists it as Pay what you want, with a suggested price of USD 60, taxes included. A purchase includes Sine Machine and future updates, and a 14-day trial is available. Each license supports up to 3 installations, but online activation is currently required, with no offline activation available yet.

Pros and Cons

Its strengths include a distinctive synthesis architecture, broad cross-platform and plugin-format support, 90 factory presets that make it easier to get started, and JSON presets that are convenient for advanced users to study and modify. The drawbacks are that it is still in Early Access, so long-term stability remains to be seen; it may be CPU-intensive on older computers or in complex bass and high-unison scenarios; and it does not support native AAX, so Pro Tools users will need a third-party wrapper.

Who It’s For and Access from China

Sine Machine is suitable for electronic music producers, experimental sound designers, synth enthusiasts, and users who want to learn additive synthesis. It is less suitable for beginners who only need quick access to conventional sounds. The main text does not specify access or payment options for mainland China, so network availability should be tested case by case. Alternatives worth considering include Arturia Pigments, Native Instruments Reaktor, Kilohearts Phase Plant, Vital, and Ableton Operator.
