Drum sounds onboard the TD-4 can be customized to suit your personal style. Just like with a real acoustic drum set, the TD-4’s kick, snare, and toms can be tuned up or down quickly across a wide range. The amount of muffling can be user-customized as well, from ‘70s-style choked funk to open-cannon stadium rock.

The TD-4 is equipped with Roland’s acclaimed Coach Mode, which helps you build speed, stamina and accuracy. Five skill-building exercises are onboard, including the new Warm Ups that lets you practice different exercises consecutively for 5, 10, or 15 minutes. The new Tempo Check also helps you keep consistent time by lowering the metronome volume when you are playing accurately or vice versa, and raising the click volume when you are playing out of time.

The TD-4’s "Quick REC” feature allows you to immediately record and play back your performance. It’s a great tool for listening objectively to what you’ve played, and charting your progress. And don’t forget the TD-4’s built-in metronome for keeping yourself in time. If you record with the internal metronome on, the TD-4 can even evaluate your accuracy afterward during playback.
