The ZOOM RhythmTrak RT-123 puts a personal rhythm section within easy reach of any musician!
  • Light weight, compact dimensions
    With a footprint corresponding to about half a magazine and a weight of a mere 550g (1.2lbs.), the RT-123 easily fits into the soft carrying case of a guitar. In the home studio, it does not take up valuable space. Taking it to a rehearsal site or onto the stage is truly easy.

  • A large number of preset patterns
    The RT-123 offers a large number of preset patterns, it will hardly be necessary to make your own. Simply by combining the 297 presets (99 x 3 banks), you can quickly create original songs. A user memory that holds 99 patterns is also available.

  • Self-lit pads and keys
    The pads and switches of the unit incorporate LED lights which make them very easy to see on a dark stage or in other low-light situations. The current mode setting and selected pad can be checked at a glance. This is also useful for recording in a home studio.

  • Drum kit focusing on real rock sounds
    80 built-in drum kit types provide realistic sound and are geared especially for rock performances.

  • 25 bass programs
    Besides drums and percussion, the RT-123 also delivers a wide variety of bass programs.

  • 3-track configuration for each pattern
    Two drum/percussion tracks and one bass track make it possible to split up complicated patterns into multiple tracks. You can for example put a snare and another drum sound on separate tracks and combine these into a single rhythm pattern. By slightly shifting tracks, interesting effects can be achieved.

  • Line input for guitar practice
    The line input allows mixing the sound of other instruments with the unit's rhythm sound.

  • The Groove Play for DJs
    The Groove Play feature lets you assign a number of desired patterns to the pads and play them at will. Patterns can of course be created freely, so there are no limits to your creativity.

  • Simple operation
    Operation is truly simple and intuitive, because there are no complex menu trees to navigate. Creative ideas can be realized on the spot.
  • Great cost-performance
    Delivering great value for money, the RT-123 is an all-round performer.
  • MIDI capability
    The RT-123 can serve as a dedicated rhythm source when receiving a MIDI note. Synchronized play using the MIDI clock is also possible, letting you use an external sequencer for example to cook up a real mind-blowing rhythm section.
