The Sines Synthesizer Black Friday deal from Cherry Audio takes 61% off this polyphonic synth plugin, so it costs $19 until Dec 1, 2026.
Sines is built on four sine-wave oscillators. Waveshaping bends those basic waves into sawtooth, square, pulse and triangle shapes, plus more complex curves that go well past the standard set.
The maker describes it as an original polyphonic synthesiser. Up to 16 voices are available.
The layout is "four of everything": four oscillators, four LFOs and four envelope generators, grouped in horizontal bands. Mini oscilloscopes and illuminated indicators give visual feedback on the sound as you edit.
Each oscillator has six waveshaper controls:
Every oscillator also gets a sub oscillator (octave-down sine) and a super oscillator (octave-up sine).
The resonant multimode filter offers 6, 12, 18 or 24 dB/oct slopes in lowpass, highpass, bandpass or notch modes. The four LFOs are tempo-syncable and cover 14 waveforms.
A four-slot mod matrix reaches nearly every parameter, and there is a tempo-synced arpeggiator. Drift controls add variation to oscillator and filter frequencies for an analogue feel.
Subtractive: wave-shape the sines into familiar waveforms, then run them through the filter.
Additive: stack sine waves at different pitches and amplitudes, in the manner of a Hammond tonewheel organ, as the maker puts it.
FM: phase modulation and ratio dials let oscillators work as modulators and carriers for four-op, DX-style synthesis.
The maker says it takes far less effort than the original 1980s instruments.
Four fully modulatable effects sections are on board:
An eight-band graphic EQ sits at the end of the chain.
MPE is supported, covering pitch, channel pressure and timbre. Polyphonic aftertouch works as a polyphonic modulation source. MIDI learn and DAW automation cover all controls.
Over 700 presets ship with it, made by a group of sound design veterans. They span evolving pads, bright FM plucks, leads and crisp percussive tones. A user guide is included.
On Mac, Sines comes as AU, VST, VST3, AAX and standalone. Windows gets VST, VST3, AAX and standalone.
Mac needs 10.13 or above, 64-bit, with native Apple M1 support. Windows needs 7 or above, 64-bit, including Windows 11. For both, a quad-core CPU and 8GB of RAM are recommended.
The maker says the code is highly optimised for ultra-low CPU load, and an oversampling control is user-adjustable.
Yes. The Sines Synthesizer Black Friday deal takes 61% off Cherry Audio's synth plugin, bringing it to $19. The offer ends Dec 1, 2026.
Sines handles subtractive synthesis, additive synthesis and DX-style FM. Four sine-wave oscillators can be waveshaped into other waveforms and filtered, stacked at different pitches and amplitudes, or set up as modulators and carriers.
Sines is a VST plugin, and it also comes as VST3, AAX and standalone on Windows. Mac adds AU to that list. Both platforms need 64-bit, and Apple M1 is supported natively.
The maker lists over 700 presets, created by experienced sound designers. They cover evolving pads, bright FM plucks, distinctive leads and crisp percussive tones. A comprehensive user guide is included too.
