Not all software synths are the same. The design, ambience and sound make some VSTi synths unique. It can be the way the interface works, the visual animation that reflects the sound output, the sound of the filter, the effect, or the way the sound can be combined and layered.
When we make music, the software tools we use need to have something that elicits a creative or emotional response, or they’re just tools.
For this list, I’ve put together a selection of the best software synths I could find. Some have been around for a while and have earned their place over time, some are perfect examples of well-executed emulation, and some sound so good that they need to be part of your sound library.
Soft synths can provide incredible value for money and sound you won’t find in the hardware world.
There are many reasons to choose a software synth over a hardware synth. Software can faithfully emulate iconic models, deliver bold new sounds, and even showcase new approaches to audio synthesis—all at prices often well below their physical counterparts.
From legendary models to complex modular setups and novel instruments, there are countless software polygons to choose from. We’ve rounded up 16 of our favorites, each with their own quirks that will keep you busy for hours.
