The Yamaha CBX-K1XG is a MIDI controller keyboard with an integrated Yamaha XG tone generator. Yamaha described it as a "MIDI sound keyboard". It was marketed as an "all-in one DTM [desktop music production]" solution.[3]

It is not to be confused with the Yamaha CBX-K1 and Yamaha CBX-K1B, which are pure MIDI controller keyboards (no tone generator).

Notable features:

  • Tone generator based on the Yamaha MU50/Yamaha DB50XG[4] (but without the "performance mode")
  • 37 velocity-sensitive mini keys
  • Built-in stereo speakers
  • Can be powered by AA batteries or via 12V DC input
  • Pitch bend wheel
  • Assignable controller wheel
    • Can be configured to send any Control Change, RPN or NRPN
    • Has extra "controller numbers" to allow easy use of common RPN, NRPN and SysEx messages used by Yamaha XG and Roland GS
    • Many useful controller numbers listed on the panel
    • Can also be configured to send Channel Pressure/Aftertouch (note: keyboard itself does not have aftertouch)
  • Can send and respond to XG, GM and GS ("TG300B") messages
  • Can be switched to an MT-32 ("C/M") emulation mode
  • MIDI in and out ports
  • Serial MIDI port
  • Sustain pedal input (quarter-inch)
  • Audio input (passthrough) via 3.5mm input
  • Audio output via 3.5mm headphone output or via twin (stereo) RCA jacks

Things to be aware of:

  • Battery life is only a few hours
  • Can become quite warm during use
  • XG effect control and other advanced features can only be controlled using an external device via SysEx
  • Selecting non-General MIDI instruments from the panel is annoying, you need to know their Bank Select numbers
