Sines Synthesizer

Cherry Audio's Sines is a polyphonic synthesizer built around four sine-wave oscillators, each equipped with an extensive waveshaping toolkit. The approach mirrors classic FM synthesis principles while expanding considerably beyond them. Each oscillator offers feedback, phase modulation, width, shape, wavefold, and drive controls alongside sub and super oscillators, enabling users to generate complex timbres from simple sine sources. The architecture supports traditional four-operator FM synthesis through ratio and phase modulation dials, though the waveshaping controls provide additional harmonic manipulation that extends beyond conventional frequency modulation.

The instrument's signal flow includes a multimode filter with extensive modulation routing, four LFOs with 14 selectable waveforms, and four envelope generators. An integrated four-slot modulation matrix manages assignments across nearly every parameter, providing the kind of deep modulation architecture expected in modern soft synthesizers. Additional features include an arpeggiator, a selection of Cherry Audio effects, and an eight-band graphic EQ, though these feel supplementary to the core synthesis engine.

Sines appeals primarily to sound designers seeking hands-on control over harmonic content and those with FM synthesis experience. The visual interface - featuring oscilloscope displays and illuminated indicators - supports exploratory sound design, though this visual feedback serves learning more than necessity. The 500-plus preset library demonstrates the synthesizer's timbral range from subtle textural sources to aggressive digital tones. For producers working in electronic, IDM, or experimental music, Sines delivers capable FM-adjacent synthesis with straightforward parameter access. Experienced users will appreciate its comprehensive modulation capabilities, though the learning curve remains steeper than menu-driven alternatives.
