Hybrid Synth VST Plugin - Free Download

Hybrid Synth with Soundfont Support

The Crystal VST plugin by Green Oak is a free software synthesizer featuring both subtractive synthesis and frequency modulation (FM) synthesis. Crystal has 3 oscillators (voices) offering both virtual analog and sampled sounds, and the possibility to load soundfonts. Each oscillator features a multistage filter- and an amplitude envelope with graphical editors. The VST plug-in features 6 modulation envelopes and 6 LFO's, all easily assignable in the modulation matrix, and a mixer section with several native effects.

VST Synth with Arpeggiator

The free Adonis Pro plug-in by Benoit Serrano features 8 oscillators/ waveform blocks each with 11 different waveforms. The waveforms can be combined by 57 different structures using ring-modulation, amplitude modulation (AM) and frequency modulation (FM). The synthesizer offers a graphical amplitude envelope (up to 8 stages), 4 graphical modulation envelopes, 4 LFO's, 2 filters, and a modulation matrix to control everything from. The Adonis VST plugin also features an arpeggiator (sync to host), an 8 step sequencer, and several effects like vibrato, phaser, delay, and chorus.

Classic VST Synth

The Synth1 plugin by Daichi is a hybrid VST synth modelled on the Clavia Nord Lead 2 (the famous 'Red Synth'). The synthesizer plugin features 2 virtual analog oscillators with FM- and ring modulation capabilities, 3 envelopes (amplifier, filter and modulation), and 2 LFO's. On top of this Synth1 has an arpeggiator and several very useful effects like chorus, delay, and bit crushing. The skin color can be changed be the user, and the plug-in comes with 128 factory presets. A true classic!
With the most resent update, Synth1 can now load up to 100 banks of patches at the same time. You can get 89 Synth1 Banks (9006 patches!) collected by EvilDragon right here and another huge bank (with some overlab of patches between the two) here
Synth1 is available for both Windows in 32 bit and 64 bit as well as Mac OSX.
