"Hybrid Drum" is a new drum form that combines acoustic and electronics. The TM-1 is a sound source module that allows any drummer to implement a hybrid drum easily. In addition to the preloaded live, fast-paced tones such as kicks, snares, cymbals and percussions, you can also play the original tone and loop phrases. Simply connect Roland various pads and acoustic drum triggers RT series to the TM-1 and add to your regular acoustic drum for a full range of performance.
