Linplug Free Alpha3 is one of the better free VSTi’s. Partially inspired by the classic polysynths of the 80s, Alpha3 is good for everything – presets cover wide range of sounds from basses, leads, to warm pads.
There are actually four versions of this subtractive synth: Alpha (commercial), Alpha CM (Computer Music magazine exclusive), Alpha Keys (Keys magazine exclusive), Free Alpha. You can compare all versions here. The sound quality of freeware version is of course very good thanks to bigger, commercial brother (which costs 79 EUR) 🙂
One thing i like the most in Alpha – it’s so easy to program it. This soft synth is great for those who want to learn basics of subtractive synthesis. The GUI is clean and looks very professional. It almost invites you to program new presets 🙂
