Sequential Prophet X

This is a great synth, with a Warm and versatile sound.

Great Constrution , Intuitive to use (for such possibilities) and "fun." Pretty much "Hands-on" with lots of knobs, and a little Menu Diving (it has 3 screns...one for the sample selection other for effects and other for more Global and General options)

This is a Synth that works with a "Synth-like" workflow, but with Samples and Synth OSCs (and can combine, blend them), not a Workstation,
The included Sample Library from 8dio, is very large, covers many things from Pianos, Synth forms, Acoustic and electric Instruments, Choirs, Strings, Percussions , and you can import and map your own samples with an Utlility in your PC or Mac.

It has 2 OSC "Intruments" that use Samples, and 2 OSC "Synths" that uses more tradicional Waveshapes. The sound can be true Stereo or depending on the voice mode (8 , 16 or 32 Voces). You can use 2 layers per patch, that can be stacked or Spllt.

The Modulations possiblities are prettyy deep and extensive ! You can get the sort of more "Bread & Butter" sounds that are expected from a Synth, "Rompler" kinda sounds or you can get pretty crazy and experimental and combine, mix them in a easy way , but be ready to waste a lot of hours , because there are indeed lots of posibilities and very different kinds of Sounds you can achieve from straight Piano sounds to Synth pacthes.

The analog Filter has a round , pleasing and warm charater that takes it away from the more "cold" charateristic sound that you get with some Digital Rompler Workstations.

Yes... it is not cheap...but if you want a Synth that goes beyond the usual Subraticte Synth capabilities and sound possibilites and can also use use Samples with workflow similiar to a proper Synth (and not a Workstation with lots of menu diving) with a very Hands on Sound Design and possibilities , i would seriously consider this.

Listen to the Demos...and if it pleases you, this can be a very great option .

I second what J_P_P says above. This is not a workstation and the built-in effects are for the most part best left alone (this applies to most synths with built-in effects). It's not a sampler either and the sample manipulation is quite limited. Yet, its hybrid nature and the extensive modulation matrix make this synth very versatile. The analog synth engine is second to none. Addition: The PX has two major flaws. First, the user interface is inconsistent and often confusing if not frustrating. For example, switching between instruments/effects on the two smaller screens is done quite differently. Second, the sample playback is prone to cracks and pops even on some factory patches. Modulating sample start, stop and loop length is therefore virtually impossible. For these reasons I decided to return it.
