Alesis DM5 Drum Module. I bought this unit to expand my Roland kit with additional pads that were plugged into the DM5 and then routed via MIDI to the Roland TD-10. On a few occasions I forgot to bring my TD-10 to the gig and had to plug everything into the DM5. I was pleasantly surprised by the quality of the drum sounds. I even ended up recording out of the DM5 a few times instead of the TD-10 and the results were stellar. There is a bit of wear on the metal case and some residue from a piece of white masking tape used to label the inputs, but the functionality is still solid. The protective plastic over the screen has never been removed. Includes the original power supply.
