How to Use the Zoom RT-223


The Zoom RhythmTrak RT-223 is an electronic drum and bass guitar machine used to create rhythm tracks for musical compositions. The RT-223 features 70 built-in drum kits and 12 different bass guitar sounds. Programming is accomplished via 13 touch-sensitive pads with three banks, offering a total of 39 sounds per kit. The RT-223 offers 440 preset patterns, covering a variety of musical styles and time signatures. Users can create and store up to 550 rhythm patterns, taking advantage of Zoom's FAST (Formula Assisted Song Translator) programming and Groove Play Mode for DJ-style pattern triggering.

Things You'll Need

  • Headphones or external amplification
  • Appropriate connection cables
  • RT-223 User Manual
  • Read the Zoom RT-223 user manual before making any connections or powering the unit. A good, basic understanding of how the RT-223 works may help you avoid mistakes or delays in setup or operation.

  • Make all connections between the RT-223 and external equipment. This may include headphones, an external mixer, powered speakers, a remote control foot switch or input from a MIDI (Musical Instrument Digital Interface) device or other equipment. Check to ensure that the volume on all devices is adjusted to the lowest level.

  • Connect the RT-223 AC power adapter or install four AA batteries. Slide the RT-223 power switch to the "ON" position, then turn on all external equipment. While tapping any of the effect pads to produce a sound, adjust the volume on both the RT-223 and all external equipment.

  • Listen to the RT-223 demo song by pressing the "FUNCTION" key until it flashes, then press the "SONG" key to activate the demo. To stop the demo song, press either the "PATTERN" or "SONG" key.

  • Experiment with the RT-223 by pressing the "PATTERN" key, then the "DRUM" key. This assigns the library of drum sounds to the 13 programming pads. Press the "BASS" key to experiment with the RT-223 bass sounds.

  • Play a pattern by pressing the "PATTERN" key, then the "PLAY" key. To change the pattern, scroll though the pattern library by pressing the "+" or "-" keys.

Tips & Warnings

  • Disconnect power before connecting or disconnecting cables to avoid damage.
  • Leaving batteries in the RT-223 during long periods of nonuse can result in corrosion.
  • Do not use near water or other liquids when using the AC power adapter.
  • Resetting the RT-223 to factory default settings will erase all user-saved data.
