LennarDigital - Sylenth1 Full version is a virtual analog VSTi  synthesizer that takes the definitions of quality and performance to a  higher level. Until now only very few software synthesizers have been  able to stand up to the sound quality standards of hardware synths.  Sylenth1 is one that does.

LennarDigital - Sylenth1 Full  version is not just another synth. It was built from a producer's point  of view. It was built to produce superior quality sound and music. It  was built to perform. A lot of research has been invested in order to  achieve unheard warmth and clarity. The graphical interface ensures the  highest level of usability so you can fully unleash your creativity.

At  its core Sylenth1 houses 4 alias-free unison oscillators, which  generate analog shaped waveforms. Each oscillator is capable of  producing 8 unison voices in full stereo, adding up to a total of 32  voices per note. With its 16 notes of polyphony this means you can play  up to 512 voices simultaneously! The oscillators perform extremely well  in both the very low (down to 0.01Hz and below!) and very high (all the  way up to half the samplerate) frequency regions without losing their  sharpness, liveliness or character. This makes them well suited for all  kinds of sounds, from the deepest basses imaginable to the highest  crystal clear bells.

On top of that there  are 2 state of the art, pure analog sounding filter sections. Each of  these consists of 4 filter stages with nonlinear saturation  incorporated, in order to emulate the warmth and drive of a real analog  filter. The resonance control can be turned up to a level way beyond  self-oscillation and combined with the drive control this makes it  possible to let the filters SCREAM! Where a lot of digital filters sound  like they're made out of cheap plastic, these filters sound rock-solid,  warm and raw.

Sylenth offers many  modulation options to sculpture the sound any way you like. There are 2  ADSR envelopes and 2 LFO's which can be used to modulate a whole set of  different parameters. Next to that, it is possible to use the extra 2  amplitude envelopes, velocity, keyboard track or modulation wheel as a  source for modulation.

The final part of this synth is the master effects section. A set of 7 professional quality sound effects and an arpeggiator, conveniently grouped into an LCD panel structure.

• Arpeggiator – 10 different melodic modes, built-in step sequencer with adjustable pitch, velocity and hold settings. Outputs Step Velocity as a modulation source.
• Distortion - Five different types of distortion (overdrive, foldback, clip, decimator and bitcrusher) in full stereo, uses 4x oversampling to minimize aliasing artifacts.
• Phaser - 6-Stage stereo phaser, with 2x oversampling, an embedded LFO, feedback and frequency spread adjustment.
• Chorus/Flanger – 4-Stage stereo chorus, with 2x oversampling, adjustable delay time, depth, rate and feedback for flanging effects.
• Equalizer - Bass and treble adjustment by frequency and amplification.
• Delay - Delay module with low and high pass filters, unique echo smearing function, pingpong mode with stereo spreading, independent left and right delay time and adjustable stereo width.
• Reverb - Smooth reverb with adjustable pre-delay, damp, size and stereo width.
• Compressor - Stereo compressor with attack, release, threshold and ratio settings, which can be used to increase punch, drive, warmth and analog feel of your sounds.

With all the functionality and processing horsepower mentioned above, you might expect that this synth would max out even the fastest CPU in no-time, especially considering the high sound quality of each single voice and effect. Well, one of the many benefits of this synth is that it doesn't. It uses highly optimized code and SSE instructions in order to reduce the CPU usage to a minimum. It will also automatically turn off any parts that are not used, to save extra CPU time. This enables you to create pure quality sound using only minimal system resources.

1. 4  band-limited unison oscillators in full stereo, each of which can  generate 8 voices per note. This allows a total of 32 simultaneous  voices for every note played, producing rich and complex sounds.
2. 2  “analog-sounding” 4-stage stereo filters per note. Each filter contains  5 independent non-linear saturation functions. The filters support  selectable low-pass, band-pass and high-pass modes with 12dB or 24dB  attenuation.
3. 16 Notes of polyphony, which adds up to a total of 512 simultaneous oscillator voices and 32 filters in realtime.
4. 4 ADSR envelope generators per note, which allow sharp attack and release.
5. 2 Low Frequency Oscillators with 11 different waveforms each.
6. 16 Modulation slots with 24 different selectable modulation parameters each.
7. Easy  to use built-in master effects section consisting of an arpeggiator and  7 sound effects: distortion, phaser, chorus, equalizer, delay, reverb  and compression.
8. Arpeggiator with built-in step sequencer, 10  different melodic modes, adjustable pitch, velocity and hold settings.  Outputs Step Velocity as a modulation source.
9. 4-Stage stereo chorus, with 2x oversampling, adjustable delay time, depth, rate and feedback for flanging effects.
10. Five different types of distortion in full stereo, with 4x oversampling to minimize aliasing artifacts.
11. Equalizer with bass and treble adjustment by frequency and amplification.
12. 6-Stage stereo phaser, with 2x oversampling, an embedded LFO, feedback and frequency spread adjustment.
13. Delay  module with low- and high-pass filters, unique echo smearing function,  ping-pong mode with stereo spreading, independent left and right delay  time and adjustable stereo width.
14. Smooth reverb with adjustable pre-delay, damp, size and stereo width.
15. Stereo compressor with attack, release, threshold and ratio settings.
16. Heavily optimized code using high-performance SSE processor instructions.
17. Easy to use user-interface.
18. Fully controllable by MIDI. Knobs can be simply assigned to MIDI CCs using the MIDI learn function.
19. Sync mode for syncing LFO and delay parameters to host tempo.
20. 2 Modes of portamento sliding, which will slide both velocity and pitch parameters in polyphonic or monophonic mode.
21. And so much more.......
