LennarDigital has released Sylenth1, a new polyphonic virtual analog synthesizer VSTi for Windows.

Sylenth1 has four unison oscillators which use an "innovate" synthesis technique that allows the generation of many simultaneous high-quality waveforms in realtime, using only minimal amounts of CPU resources. It also features two "analog sounding" filter sections, which can be taken way past the point of self-oscillation. These filters incorporate several non-linear saturation stages to produce harmonically rich sounds. Sylenth1's extensive modulation options offer possibilities to sculpture the sound, and it has a set of six built-in mastering sound-effects.

Features:

• 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 "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.
• 8 Notes of polyphony, which adds up to a total of 256 simultaneous oscillator voices and 32 filters in realtime.
• 4 ADSR envelope generators per note, which allow sharp attack and release.
• 2 Low Frequency Oscillators with 10 different waveforms each.
• 16 Modulation slots with 24 different selectable modulation parameters each.
• Easy to use built-in master effects section consisting of 6 sound effects: distortion, equalizer, phaser, delay, reverb and compression.
• Three different types of distortion in full stereo, with 4x oversampling to minimize aliasing artifacts.
• Equalizer with bass and treble adjustment by frequency and amplification.
• 6-Stage stereo phaser, with 2x oversampling, an embedded LFO, feedback and frequency spread adjustment.
• 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.
• Smooth reverb with adjustable pre-delay, damp, size and stereo width.
• Stereo compressor with attack, release, threshold and ratio settings.
• Heavily optimized code using high-performance SSE processor instructions.
• Easy to use user-interface.
• Fully controllable by MIDI. Knobs can be simply assigned to MIDI CCs using the MIDI learn function.
• Sync mode for syncing LFO and delay parameters to host tempo.
• 2 Modes of portamento sliding, which will slide both velocity and pitch parameters in polyphonic or monophonic mode.

Sylenth1 is available as a VSTi for Windows and costs €159. A demo version is available.
