Ratings and Reviews

Pretty good for $1!


You can make some nice sounds with this synth. However, there are a few things I'd like to see.

•Another oscillator
•OSC Unison
•Poly/Legato modes
•LFO Sync

Thanks! :)



This works like a real vintage synth! My only complaint is that the glide is a bit too sensitive. It's hard to find a subtle sweet spot for leads. Notice I still gave 5 stars. This thing is amazing!

well done


A simple inexpensive but really good sounding and well designed synth. The oscillators and filters are well done and have great tone and filters. Everyone into synthesis should have this!
