Dave Smith Sequential Prophet X review | MusicRadar

musicradar.com

The Dave Smith Prophet X is a standout hybrid synth that merges sampling and synthesis, encouraging new creative possibilities. Its robust build, intuitive interface, and rich modulation options make it a joy to use. The integration of 8DIO's expressive samples adds depth, though the limited polyphony in dual layers might frustrate some. The lack of a flexible voice allocation per layer and inability to bypass effects for specific layers are minor drawbacks. Despite these, the Prophet X's innovative design and sound versatility make it a worthy investment for those seeking a fresh approach to sound design.

Sonic LAB: Prophet X Hybrid Synth - Big Fat Review

sonicstate.com

The Dave Smith Prophet X is a powerhouse hybrid synth that blends synthesis and sampling beautifully, offering an inspiring experience for those who can afford its hefty price tag. With features like stereo analog filters, a 256GB SSD with 150GB of high-quality samples, and an extensive modulation matrix, it excels in creating lush, ethereal soundscapes. However, its DSP oscillators don't quite match the warmth of analog, and the limited polyphony and articulation options mean it won't replace dedicated sample libraries. Despite its cost, the Prophet X's sonic potential and future updates make it a worthwhile investment for serious musicians.
