Dave Smith Instruments Sequential Prophet X Synthesizer
Sequential Prophet X is a potent fusion of samples-plus-synthesis and is Sequential's most groundbreaking Prophet yet. At its heart, it's a bi-timbral, 8-voice-stereo, 16-voice mono/stereo, 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 150GB of included samples from acclaimed sound developers 8Dio and all of the powerful synthesis tools you've come to expect from Sequential, Prophet X has a musical voice uniquely its own.
On the sample side of things, in 8- and 16-voice modes Prophet X provides two independent stereo digitally sampled instruments per voice (4 in stack or split modes). 150GB of factory sample content was created by 8Dio, known for pioneering so-called 'deep sampling.' You'll find a diverse collection of acoustic and electronic instruments as well as plenty of edgy ambient and cinematic effects. You can shape the samples through loop manipulation and sample stretching as well as Prophet X's sound-sculpting modulation functions. Each sample instrument has its own tone control for high pass or low pass filtering. 50GB of additional internal storage is dedicated to importing user samples and 3rd party sample libraries.
Prophet X allows users to import their own samples to create custom instruments and content, with sample import and mapping handled by an easy-to-use software application created by 8Dio. The Mapping Utility application has a familiar and user-friendly layout with all core features and options necessary to fully map your samples organized in a single window. From here you can import compatible sample files, audition them, map them, stretch their ranges and assign them to various banks and categories in order to create your own unique and custom sample sets.
On the synth side, Prophet X gives you the power of a classic Prophet with two high-resolution digital oscillators that feature both classic waveshapes and a supersaw for more timbral possibilities. Use the Shape Mod control to manually dial in a desired waveshape width for any of the classic sine, sawtooth or pulse waves, or use an LFO or other mod source for continuously shifting timbre. You can shape the raw sounds with all the classic synthesis functions you'd expect, including 4 syncable LFOs with slew and phase offset, 4 loopable five-stage envelope generators and a 16-slot mod matrix with dozens of modulation sources and destinations.
Stereo filters for depth and impact
At the heart of the Prophet X's powerful sound are its new 24dB/octave resonant low pass filters, which are based on the classic SSM2044 IC used in Rev 1 and Rev 2 Prophet-5 models. In 8-voice mode there are separate filters in the left and right channels for a true stereo signal path; these add exceptional presence and fullness to both the samples and the oscillators. For additional polyphony, you can switch Prophet X from 8-voice stereo mode to 16-voice mono/stereo mode, which is useful for stacks and splits, or 32-voice paraphonic performance mode when using a single sampled instrument and oscillator.
Polyphonic step sequencing
The polyphonic step sequencer provides up to 64 steps and up to 6 notes per step. You can create a different sequence for each layer if working in stacked or split voice mode, making it a powerful tool for composition or performance. Sequences can have ties and rests and can sync to an external MIDI clock. The arpeggiator features note repeats and re-latching and can be synced to external MIDI clock.
Two effects per layer
A dual effects engine provides multiple reverbs, two delays (standard and BBD-style), chorus, phaser, flanger, ring mod, vintage rotating speaker, high pass filter and distortion. In stacked or split voice mode you can apply two different effects to each layer. Effects parameters can be modulated through the mod matrix.
Roadworthy and studio-ready
With loads of sonic firepower and personality, a five-octave, premium-quality, semi-weighted keyboard with velocity and channel aftertouch, an integrated power supply, MIDI USB support and three crisp OLED displays, Prophet X fits into any music rig or gig, in the studio or on the road.
