SynthMaster 3 is a modular software synthesizer for producers, composers and sound designers who want several synthesis methods inside one instrument. Its architecture supports up to 16 layers per instance, combining wavetable, granular, additive, FM and sample playback with generators, filters, waveshapers, effects and modulation sources. The product runs on Windows and macOS as plug-in software, with a standalone version documented for Windows.

According to the vendor's pricing page, SynthMaster 3 costs $99 one time. The published plan includes modular architecture, VST2, VST3, AudioUnits and AAX formats, 3150 factory presets, a multisample editor, and waveform and wavetable editors. The product also includes a preset browser with filtering and NKS preview support, plus WAV and AIFF import for multisample creation. That combination gives the single paid plan a wide scope for both preset-based work and custom sound design.

Its main strength is depth across different synthesis workflows rather than a narrow focus. Layer-based envelopes, LFOs and scaler sources can shape each layer, while per-layer arpeggiators and sequencers add pattern-focused control. The editors and sample import tools extend the instrument beyond preset playback. SynthMaster 3 suits users who want one synthesizer for layered patches, electronic sound design and sample-based textures. Users seeking a free instrument, a short-term evaluation beyond the 30-minute demo limit, or a standalone workflow documented for macOS should look elsewhere.
