Here's what Disaster Area says about the DPC-8EZ:

A bypass looper can streamline your rig in ways you never thought possible – imagine being able to tap one footswitch to go from verse to chorus to bridge of a song, while changing up to eight different effects plus two MIDI devices!

If you already have a MIDI controller, the DPC-8EZ can act as a MIDI “slave” on any available channel. You can even connect two or more DPC-8EZ to control more pedals.

The DPC-8EZ is fully compatible with the Disaster Area Gen3 pedal controllers – connect it to add eight effects loops under MIDI control. The DPC-8EZ can also function as a standalone MIDI controller for up to two devices.

What’s new in Gen3?

The switching system at the heart of the DPC-8EZ is so robust and transparent that we didn’t dare to change it! We did add a few nice new features, though!

Faster, more powerful 32-bit processor
Improved USB MIDI capabilities
User-definable LED brightness (10 levels)
New MIDI mode controls up to two MIDI devices with program select and tap tempo
Preset mode now controls MIDI and loops
Tuner output jack doubles as a MultiJack
MultiJack functions as MIDI input & output OR double MIDI output
MultiJack is directly compatible with Chase Bliss, Empress, or Meris pedals
