Dave Smith Instruments Sequential Prophet XL 76-key Samples-Plus-Synthesis Hybrid Synthesizer

   (0 reviews)

Dave Smith Instruments Sequential Prophet XL is a 76-key version of the acclaimed Prophet X, a potent fusion of samples-plus-synthesis and the most ground-breaking evolution of the Prophet yet. At its heart, it's a bi-timbral, 8-voice stereo, 16-voice mono, 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 internal samples from acclaimed sound developers 8Dio and all of the powerful synthesis tools you've come to expect from Sequential, Prophet X and Prophet XL have a musical voice uniquely their own.

Sample engine

On the sample side of things, in 8- and 16-voice modes Prophet XL provides 2 independent stereo digitally sampled instruments per voice (4 in stack or split modes). The 150GB 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 Prophet XL'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 external sample libraries. Support for user-created samples is planned for release soon; meanwhile, add-on sample packs are available from 8Dio now.

Synth engine

On the synth side, Prophet XL 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 5-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 Prophet XL's powerful sound are its 24dB/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 Prophet XL from 8-voice stereo mode to 16-voice mono mode, which is useful for stacks and splits, or 32-voice paraphonic performance mode when using a single sampled instrument and single oscillator.

Polyphonic step sequencing

The polyphonic step sequencer provides up to 64 steps with up to 6 notes per step. You can create a different sequence for each layer when 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 also be synced to external MIDI clock.

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.

Roadworthy and studio-ready

With loads of sonic firepower and personality, a 76-key semi-weighted premium-quality keyboard with velocity and channel aftertouch, an integrated power supply, MIDI-over-USB support and three crisp OLED displays, Prophet XL fits into any music rig or gig, both in the studio and on the road.
