Sylenth1 is a polyphonic virtual analog synthesizer.
It 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.
- 16 Notes of polyphony, which adds up to a total of 512 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 11 different waveforms each.
- 16 Modulation slots with 24 different selectable modulation parameters each.
- Easy to use built-in master effects section consisting of an arpeggiator and 7 sound effects: distortion, phaser, chorus, equalizer, delay, reverb and compression.
- Arpeggiator with built-in step sequencer, 10 different melodic modes, adjustable pitch, velocity and hold settings. Outputs Step Velocity as a modulation source.
- 4-Stage stereo chorus, with 2x oversampling, adjustable delay time, depth, rate and feedback for flanging effects.
- Five 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.

eod Hello.
I have purchased Sylenth1 a while ago however am having registration issues within Windows 8 preview. I still hear the nagging demo mode sound even though my name appears in the Registration info window within the plugin. can anyone else confirm this and will there be a fix in the future?
Regards,
Chris
Steve196 Hi Chris,
In the beginning I experienced the same kind of problem, but it was solved once i had removed the demo version(s) properly. I use Windows 7, so maybe Windows is indeed the cause but i have some doubts about that.

Steve
AmericanYellow Hey all,
I had the same issue in Window 7 64 bit, but re-installing a few times fixed the problem. I now have the same issue again on 1 of 2 computers both running Windows 8 Release preview 64-bit. Both computers have the same hardware, software, and were set up at the same time with the same procedures. Re-installing does not work, just spent the entire month trying to figure it out, and I've finally given up. Also, Sylenth causes every DAW I use to eventually crash after a couple of the repeated nagging noises. Based on my experience and other forum posts, it seems to be a somewhat random problem with Sylenth. Annoying!!!!!
Regards,
Die Hard Sylenth Fan

gjfurlan Hello,.
I downloaded the demo for Sylenth1 for my 64-bit PC with AMD Athlon, from LennarDigital's website, but I do not know how to get the program to run. I have FL Studio 10. Can anyone help me out? I would like to buy the Sylenth1 but I need to know that I will be able to run it on my PC first.
Thanks,.
Greg.
Steve196 Hi Greg,.
You could copy the file to Imageline/FLstudio/Plugins/Fruity/Generators. Then start up FL, go to channels/more and then refresh. Sylenth1 should then be visible under VST1 and 2 plugins. You can then select it within your channels, where you can also find other generators like FL Keys. I have FL 10 and it works fine with Sylenth1. Hope this info gets you started. Kind regards, Steve.
gjfurlan Thank you Steve! I will do that! I really appreciate your help with this.
Greg.
Steve196 Hi Greg,.
You're welcome! FL10 can pick VST's from other folders as well, even outside FL. For example within the VST folder in Steinberg. Please let me know if it still doesn't work. Kind regards, Steve.
gjfurlan Hey Steve,.
I got it to work thanks. My friend my Belgium was telling me since I like trance that I should get the Sylenth1 definitive collection, but I did not see it available for download on Lennar Digital's website. Is it an expansion pack for the regular Sylenth1 download?
Thanks,.
Greg.
Steve196 Hi Greg,.
Within Sylenth1's /menu/check for updates you will see a list of downloadable sounds (presets). But those are not recent (2009 and 2010) and not grouped by genre. I don't know the 'definitive collection'. There are many presets or pathes packages for sale, most of them by genre. For examples at Loopmasters (Trance Sylenth1 patches) or at Samplemagic. All those sounds can be created by yourselve, by trail and error, but these patches may save you a lot of time. And patches can also helpfull in learning how these sounds were created, especially with Sylenth1 were you can quickly see all the setting. Adding some drumsamples might also be a way to save time when it comes to adding a good kick drum, drumloops, risers, bombs, etc. There several nice "the making of" or "in the studio with" video's on Youtube which have FL and Sylenth1 in it, for example one featuring AVICII. It may not be everyone's cup of tea, but these vids can give useful insight in using FL, Sylenth1, etc. Kind regards, Steve.
