This workstation exceeded reviewers' expectations, especially when it comes to its sound engines and functionality. Many of them mentioned its on-board effects engine and virtual analog engine provide exceptional quality sounds. Additionally, presets such as electric pianos and orchestral sound quite authentic. Aside from that, it's sequencing capabilities are also quite intuitive and it had flexible layering and splitting functions. Regarding its construction, it is overall very sturdy and quite durable.


Some reviewers mentioned that the size of the screen display needs more improvement. Additionally, the hammond organ sounds fair enough but not so realistic, which isn't a problem if you opt out of using hammond organ presets.


This is a great choice if you are looking for a workstation with excellent analog modelling capabilities.
