  • High-end sample instruments
  • Amazing arpeggiator
  • A library of effects
  • A bit incorrect simulation of the classic synths

Verdict: IK Multimedia Syntronic is a complete collection of software synths that you can purchase as one whole or separately. While working on these tools, the developers used 17 analog and digital classical instruments, as well as 38 synthesizers.

This DAW software probably contains the largest number of presets - over 2000, as well as a huge collection of different filters for your audio tracks. With their help, you can easily select the type of sound you need, and it will mimic the one produced by an original instrument as accurately as possible. You can also layer four virtual machines together, which is ideal when you want classic 70s, 80s and 90s sounds.

6. UVI Falcon

 
Has a structure of samples
  • Straightforward search
  • Advanced sound generation
  • Huge modulation potential
  • Confusing UI

Verdict: UVI Falcon is the best synthesizer software for those, who don’t want to imitate the classics, but to please the audience with new, up-to-date sounds, timbres and rhythms. At the same time, the program offers excellent functionality for traditional track synthesis and can be used as music management software.

Unlike other programs designed for this task, UVI Falcon has an unconventional structure. In fact, this is a multitimbral sampler with a Multi (.uvim) patch consisting of unlimited parts. A part functions as a slot for a single program that contains a level fader, inserts and auxiliaries. A program (.uvip) is a key sound-producing patch that is assigned to keygroups by oscillators. The keygropus are further combined into layers.

7. Native Instruments Massive

 
The most feature-packed synth
  • Convenient modulation system
  • Advanced filters and oscillator
  • Gradual learning curve
  • Disappointing presets

Verdict: Native Instruments Massive is a hybrid synthesizer that combines the best features of similar programs, but offers a more intuitive interface. The structure is organized in such a way that the most frequently-used settings (oscillators, noise control, feedback controls, etc.) are located in the main menu of the program.

You can choose from 82 wavetable oscillator shapes, adjusting both simple waves and more complex noises. Each oscillator has its own intensity control and you can also apply filters. There is a total of 11 filter modes, as well as standard two- and four-pole high and low pass filters, with the help of which you can create something more interesting.
