ROLI's Blocks platform is designed to be modular, so you can buy more units as and when you need them. However, if you want a triple-hit in one go, plus a comprehensive software bundle, then take a look at the Songmaker Kit.
Now widely available, this contains a Seaboard Block, a Lightpad Block M and a Loop Block. The two former devices serve as expressive keyboard and pad controllers, with the latter being used to control recording and sound switching features. Additionally, you get a Snapcase that can be used to house the Blocks and keep them safe when you’re on the move.
The Songmaker Kit works with PC, Mac and iOS and costs £550/$650. Obviously, if you don’t need all of its elements then you might choose to save some money and just buy the Blocks you want separately, but the Kit does give you a cost saving if you want all three of the included units, the Snapcase and the included software.
