Sylenth1 is a virtual synthesizer that allows to generate notes similar to analog synthesizers in sound and so as quality. Sylenth1 has 4 unison oscillators that generate sounds in real time and do not consume a lot of RAM. Special Sylenth1 VST-synthesizer filters help a beatmaker to achieve a harmonious sound.
The plugin interface is divided into these parts: Oscillator, Amplitude Envelopes, Mixer, Filters, Filter Control, Mod Env, LFO, Misc, and Master Effects section.
Someone says that this plugin outdated due to its cumbersome interface and too difficult to learn, but it still really popular among sound producers.
Guitar Rig is VST electric guitar combo developed by Native Instruments. The plugin can be used to play live through connecting an instrument through an external sound card. In electronic music, it is used in conjunction with a sound generator (usually it is a virtual guitar, but any other VST instrument like Sylenth1 can be used). Guitar Rig can emulate the following sound effects: Overdrive, Reverb, Distortion, Delay, Compression and their combinations. Guitar processor has a big library of classic and modern amplifiers.
Some additional buns are tuner and a metronome.
System requirements: Intel Core Duo or AMD Athlon 64 and 2 (better 4) GB of memory.
The Arturia synthesizer is designed for fans of classic pianos. In addition to being used in FL Studio the plugin can runs as a standalone application with a midi controller (real keyboard) connected. Arturia Piano V2 contains 8000 sound presets from classic Grand piano to rare types of piano which was made of glass or metal.
Are you a true drummer? EastWest PRODrummer – VST/AU library of virtual drums weighing more than 100 GB. A little-known, but high-quality VST plugin containes WAV format samples which was recorded in a studio using a professional drum kit. EastWest PRODrummer is equipped with fine settings for quantization, swing, delay and is distributed with a large library of presets and also works as a standalone application because it has built-in equalizer, compressor, limiter, saturator and reverb.
FabFilter is one of the few equalizers with dynamic alignment. Automatically adjusts the attack and release time, cuts off conflicting frequencies and equalizes the sound volume. The plugin has many built-in presets of different genres of music adjusting by beatmaker itself.
Another advantage is "spectral links". This is the separate graphical interface for comparing the spectras of several tracks in a single window. FabFilter Pro allows you to determine the frequency intersections of different instruments (e. g. syntheizer and bass) and edit them during the track plays.
The main disadvantage of FabFilter equalizer is really high price.
