What to know before buying
Listing details to confirm
The listed dimensions conflict: one entry gives 25.3D x 42.3W x 3H centimetres, while another gives 25.3 x 42.37 x 4.57 cm; confirm the applicable dimensions if desk fit matters. The listed control methods also say “App,” while the described operation is through physical buttons, faders and knobs, so the app-control entry is unconfirmed. The USB port count is listed as one, but the connection is also called a USB 2.0 Type B interface. Confirm any detail that affects your setup.

Less suited to
