Voice-controlled analogue-style synthesiser

Alien Solo screenshot

Alien Solo is a fully-featured monophonic synth that is controlled by your voice. Sing, hum or doo-wop the lead or bassline and then dial up the synth patch you want. You can also process other monophonic sources, but the pitch tracking function is optimised for the human vocal range.


Why "Alien Solo"? Picture those aliens blowing into weird instruments in the Mos Eisley Cantina on Tatooine in Star Wars IV...

   NB: This is a 32-bit plugin. If you are using a 64-bit host app, you will need a bitbridge. I recommand jBridge.

   NB: This plugin may not work at sample rates of 192 KHz. I recommend using sample rates of 96 KHz or below.

(If your host app does not support mono effecst, use this VST Stereo version.)
The freeware versions let you audition the 8 factory presets, with the rest of the controls disabled.

Alternatively, you can download it from, where (we are told) it has received some sort of famous award.
