The TM-2 from Roland is a compact and battery powered trigger module that provides a simple solution for acoustic drummers looking to enhance their kits with electronic percussion. Two trigger inputs support a wide variety of the company's pads and drum triggers, while the ready-to-play sounds are optimized for augmenting live acoustic drums.
Studio-quality multi-effects are available for processing the kits, and triggering custom WAV sounds, loops, and backing tracks can be done via an SDHC card. Just copy any WAV audio files from a computer onto an SDHC card, and then insert it into the trigger module's card slot.
MIDI I/O allows for triggering sounds in V-Drums modules, keyboards, and synthesizer modules, and when connected to a computer via a MIDI interface, MIDI data can be recorded and sounds played within most popular music software. It's also possible to play both internal sounds and WAV sounds stored on an SDHC card from an external MIDI device.
