How does the TD-516 differ from the TD-716?

Both use the same V51-family sound approach, but the TD-716 pairs it with higher-end pads and digital snare, ride and hi-hat hardware. The TD-516 gives you the module and lets you add digital pads through its USB inputs.

Can I use V71 expansions on the V51 module?

Yes. Roland states that all V71 module expansions work on the V51, so you get flagship sound content on the mid-tier module.

What can I connect to the USB digital inputs?

There are three USB digital inputs. You can add a digital snare, a digital ride or a digital hi-hat, one per input.

Where do I get extra sounds?

The V51 connects to Roland Cloud and to SoundWorks from DW Drums, so you can download additional samples and kits.

Is this kit ready to play out of the box?

It is a full electronic kit with pads, rack and module. Expect to assemble the rack and set pad positions, and to spend time dialing in kits on the module.

Who is the TD-516 aimed at?

Drummers who want flagship-level sounds and a clear upgrade path without moving to the top-tier kit. It suits home and studio players more than touring drummers who need the most rugged hardware.
