Sequential Prophet X Synthesizer (61-Key) The Next Evolution of the Prophet. 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. Sample Engine. 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. Synth Engine. 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.
