The keytar is making a comeback in both ironic and un-ironic contexts. One thing’s for sure, this is a unique looking keyboard. It’s space age and toy-like but professional at the same time, with a good measure of home keyboard feel thrown in too. This amazing 37-key synth lets you play expressively, even when you attach a strap and play it on the move. Build-quality is similar to its more expensive brother (though still pretty plasticky) and the off-white case looks a little uninspiring. However, for a little more outlay, there is a black version available that looks more serious. The Lucina AX-09 can be run on mains or battery power and has plenty onboard in terms of sounds and features.
According to several user reviews, they have praised a Roland Lucina AX-09 for the Compact and easy to use; A good range of usable sounds onboard; USB audio file playback; Cool look and compact size; Many impressive sound presets.
