Reveal Sound Spire is a powerful software polyphonic synthesizer that combines the character of hardware-inspired synthesis with the flexibility and convenience of modern software instruments. Designed for music producers, sound designers, and electronic musicians, Spire provides an extensive sound engine for creating everything from deep basses and expressive leads to atmospheric pads, plucks, sequences, arpeggios, and experimental effects.

At the heart of Spire are four multimode polymorphing oscillators, each offering multiple synthesis modes including Classic, Noise, FM, AMSync, SawPWM, HardFM, and Vowel. Its unique unison engine can provide up to nine unison voices per oscillator, making it possible to create wide supersaw-style sounds, powerful leads, rich chords, and dense layered textures.

Spire also features two multimode filters with a selection of analog and digital filtering models. Combined with its modulation architecture, the synthesizer provides extensive control for shaping and evolving sounds. The modulation section includes four macros, four envelopes, four LFOs with morphing shapes, and a 15-slot modulation matrix with multiple sources and targets.

For sound processing, Spire includes a comprehensive built-in effects section featuring Shaper/Decimator, Phaser/Vowel, Chorus/Flanger, Delay, and Reverb. An X-Comp multiband compressor and three-band EQ are also available for adding additional punch, definition, and balance to the final sound.

The instrument includes two steppers and an arpeggiator, making it especially useful for creating rhythmic patterns, evolving sequences, melodic phrases, and complex electronic textures. The factory library contains more than 1,000 presets, covering arpeggios, bass sequences, leads, pads, plucks, drums, and FX.

The current official release listed by Reveal Sound is Spire. On Windows, Spire is available for 64-bit systems in VST2/VST3, AAX, and CLAP formats. On macOS, it supports Intel and Apple Silicon systems running macOS 10.15 or later, with AU, AAX, CLAP, VST2, and VST3 formats available.
