by VCV
If you always wanted to experiment with modular synthesis, VCV Rack is the place to start. It delivers all the sonic capabilities of a hardware modular synth without costing a fortune or taking up an entire room. The software runs standalone and is also available as a VST3 plugin for use inside your DAW. Hundreds of free community-developed modules are available, covering everything from basic oscillators and filters to complex sequencers and granular processors.
The module library is enormous and continues to grow. VCV Rack lacks the tactile feedback of hardware knobs and patch cables, but it’s hard to complain when the software is free, and the creative possibilities are effectively unlimited. If VCV Rack feels overwhelming at first, check out ModulAir by Full Bucket Music (listed below) for a simpler introduction to modular patching.

Another FM synthesizer worth checking out is Exakt Lite by Sonicbits. Unlike Dexed, which faithfully recreates the DX7, Exakt Lite does its own thing.
