It remains our favourite freeware synth, though, based largely on its blend of simple usability and excellent sound. OB-Xd isn’t the flashiest synth is this round-up, nor is it the newest, despite being updated to version 2 in recent months. Your needs here will depend on your chosen DAW, so make sure you check up on what plugins yours can host before downloading. We’ve listed with each synth what operating systems it can be used on, and available formats (standalone, VST, AU or AAX). The only other factor to consider is compatibility.

One of the great things about freeware is that it gives users the opportunity to try out these different types of synth design for free, so if you’re not sure which is for you, why not try downloading several styles of synth to see what suits you best? In the list below you’ll find a variety of synthesis types, from virtual analogue to FM, wavetable, modular and hybrid instruments that combine multiple approaches. Some emulate or clone the sound of classic hardware instruments, while some are original designs of their own. That being said, many freeware instruments - particularly those that are open-source - are lovingly maintained and developed either by their original creators or a community of users.Īs with commercial plugins, freeware synths come in all shapes and sizes. The most significant risk with freeware synths is that you can’t always count on long-term support and upgrades, meaning that free synth you love may not keep pace with the changing needs of your DAW or operating system.
