Dave Smith Sequential Prophet XL
The Next Evolution of the Prophet
The Sequential Prophet XL is a 76-key version of the acclaimed Prophet X — a potent fusion of samples-plus-synthesis and the most ground-breaking evolution of the Prophet yet. At its heart, it’s a bi-timbral, 8-voice-stereo, 16-voice mono, 32-voice paraphonic synth with a newly developed sound engine that powers two simultaneous 16-bit, 48kHz sample-based instruments plus two high-resolution digital oscillators — all processed through analog filters. With 150 GB of internal samples from acclaimed sound developers 8Dio, and all of the powerful synthesis tools you’ve come to expect from Sequential, the Prophet X and Prophet XL have a musical voice uniquely their own.
