The deal

$29 at Sweetwater (down from $49). Sale runs through May 15, 2026.

What it is

SynthMaster One is a semi-modular wavetable synthesizer from KV331 Audio, built on the same sound engine as the full SynthMaster but streamlined to a single-layer, single-screen interface. It delivers true wavetable synthesis alongside analog-voiced zero-delay feedback filters, making it capable of everything from glassy digital textures to warm, driven bass tones. The synth ships with 500 factory presets designed by a team of professional sound designers.

Who it's for

Producers who want deep sound design without a cluttered workflow - SynthMaster One suits electronic, ambient, cinematic, and experimental producers who need a versatile soft synth that covers pads, leads, basses, and evolving sequences in a single plugin.

Key features

• Two oscillators, each with up to 16 unison voices, support true wavetable synthesis with importable wave files and a built-in wavetable library
• Sub oscillators connect to main oscillators in five modes including amplitude, ring, frequency, and phase modulation
• A 16-step multimode arpeggiator/sequencer with per-step velocity, note length, slide, and hold controls lets you build complex rhythmic patterns
• Eleven studio-grade effects - including Distortion, Vocoder, Chorus, Reverb, Compressor, and 6-band EQ - load into six insert slots, keeping your signal chain inside the plugin
