Description
 

This synth is great for dance/trance music, awesome leads and fantastic basses, there are also drum sets.
Arpeggiator has a lot to offer, and 6 knobs on the left gives you quick access to basic parameters.
Knobs are a bit wobbly (in my unit) and keyboard feels cheap comparing to jx307 or yamaha sy85.
