Sequential Prophet X Keyboard
The Sequential Prophet X is a potent fusion of samples-plus-synthesis and is Dave Smith’s most ground-breaking evolution of the Prophet yet. At its heart, it’s a bi-timbral, 8-voice-stereo (16-voice mono) 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 Dave, the Prophet X has a musical voice uniquely its own.
