This Prophet X is our shop model that was briefly and lightly played when we got it. But has mostly been sitting in its box waiting for us to list it as our storefront has been closed during the pandemic. This is in Mint/B-stock condition and includes its original packaging. We added on the 8dio T8, OBX and Jupiter-4 add-ons to this ($144 value) as well as a Digital Deck double quilted nylon cover that was made for this specific model ($53.99 value). Serial Number is 137.
About the Prophet X:
The Next Evolution of the Prophet
The Prophet X is a potent fusion of samples-plus-synthesis and is Dave Smith’s most ground-breaking evolution of the Prophet yet. At its heart, it’s a bi-timbral, 8-voice-stereo (16-voice mono) 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 Dave, the Prophet X has a musical voice uniquely its own.
Sample Engine
On the sample side of things, the Prophet X 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. Fifty gigabytes of additional internal storage is dedicated to importing external sample libraries. Support for user-created samples is planned for December 2018. Add-on sample packs are available from 8Dio on product release.
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 X’s powerful sound are its new, 24 dB-per-octave resonant low-pass filters, which are based on a vintage design. 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 X from 8-voice stereo mode to 16-voice mono mode, which is useful for stacks and splits.
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, 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.
