The Sequential Prophet X is a potent fusion of samples-plus-synthesis and is Sequential’s most ground-breaking evolution of the 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 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 has a musical voice uniquely its own.
On the sample side of things, in 8- and 16-voice mode, the Prophet XL provides two independent, stereo, digitally sampled instruments per voice (4 in Stack or Split mode). The 150 GB of internal sample content was created by 8Dio, known for pioneering “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, sample stretching, and the Prophet X’s sound-sculpting modulation functions. Each sample instrument has its own Tone control for high-pass or low-pass filtering. 50 GB of additional internal storage is dedicated to importing user samples and 3rd party sample libraries.
On the synth side, the 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. Using the Shape Mod control, you can 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 of 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 XL’s powerful sound are its new, 24 dB-per-octave resonant low-pass filters, which are based on a vintage design. 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 the Prophet XL 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.
Poly 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, re-latching, and can be synced to external MIDI clock, as well.
Two Effects per Layer:
A dual effects engine provides multiple reverbs, 2 delays (standard and BBD), chorus, phase shifter, 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.
Road-worthy 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, the Prophet X fits into any music rig or gig — in the studio or on the road.
Sequential today announced several developments that have enhanced their flagship hybrid samples+synthesis keyboard, the Prophet X. These include a new OS, two full-featured third-party sample editing applications, and several add-on sample libraries from 8Dio and other sound developers.
The new 2.2 OS adds several user-requested features including 24 additional User Sample Groups, support for crossfades on forward-backward loops, and the capability to modulate between tempo-synced LFO values. The new features build on an already-powerful foundation of sound shaping tools and the fusion of samples and synthesis. The new OS is designed for both the Prophet X and Prophet XL and can be downloaded from the Prophet X/ XL support page on Sequential’s website.
Another significant development for the synthesizer, which supports up to 50 GB of user-created sample content, is the availability of two powerful third-party sample creation/editing tools. The first, PXToolkit, is a free application from developer ThinkerSnacks which offers drag and drop file creation with automatic extraction of pitch and loop metadata from .WAV files, as well as support for multi-sampled instruments, multiple velocity layers per key, and round-robin sample selection and playback. The software can be downloaded free of charge from the ThinkerSnack website.
The second tool, SAMPLEROBOT Pro 6.5 from Skylife, brings Prophet X support to their popular and highly-acclaimed auto-sampling and sample editing application. It supports multi-sampled instruments, multiple velocity layers per key and powerful looping and editing tools. The software is available for purchase from Skylife’s website.
Also noteworthy is the abundance of third-party add-on sample packs that can be imported into the Prophet X and manipulated as part of its hybid sound engine. The most prolific among the various sound developers creating content for the synthesizer is 8Dio, with eight Prophet X-specific products to date. These include deep-sampled versions of vintage instruments such as the Yamaha CP70, ARP 2600, Oberheim OB-X, Sequential Prophet-5 and T-8, Roland Jupiter 4, and Moog Prodigy and Minimoog Model D synths.
