Don’t let Prelude’s affordability mislead you ― it sounds like a keyboard costing twice the price. Prelude is equipped with hundreds of top-quality sounds derived from Roland's famous sound modules.

Synths with built in speakers always intrigue me for some reason. The HS60 and Juno-106S for example are full blown Roland Juno-106es with built in speakers.
