Dave Smith Instruments Prophet 12

With its hybrid design and 12-voice architecture, the Sequential Prophet 12 synthesizer delivers impressive sound versatility and a rich feature set, making sound design both fun and intuitive. Its robust modulation capabilities and unique Character section allow for a wide range of sonic exploration. However, some users may find the aftertouch overly sensitive, and the headphone output is limited to one layer, which can be a nuisance during live performances. Despite these minor drawbacks, the Prophet 12 stands as a worthy flagship instrument in the storied Prophet lineage, merging classic analog warmth with modern digital precision.

The Sequential Prophet 12 Synthesizer stands out with its unique sound and versatility, making it a joy for live performances and studio work alike. Its intuitive interface and solid build quality enhance playability, allowing musicians to dive deep into sound design effortlessly. However, the inability to specify voice allocation in unison mode and the lack of a global bypass for effects may frustrate some users, particularly at this price point.
