The Arturia Beatstep USB, MIDI, and CV Controller and Sequencer is a USB class-compliant driverless controller that enables control over DAWs, loop-triggering software, drum software, VST instruments, VST effects, DJ applications, MIDI instruments, and analog equipment that has control voltage (CV) connections. The unit features sixteen pressure and velocity sensitive pads, sixteen rotary encoders, transport and preset controls with sixteen presets, and a jogwheel for transpose, rate, and level. When placed in controller mode, the pads illuminate red via backlit LEDs. In this mode, a performer can use the pads and rotary encoder knobs to control drum software on an iPad (with camera connector kit) or a computer such as BFD, Kontakt, Ableton Live's Drum Rack, EZ Drummer, Addictive Drums, Reason Kong, or Geist. The controller can also be used to trigger clips or tracks in production and DJ software such as Ableton Live, Traktor, and Serato. The rotary encoders can be MIDI mapped to control filters, EQs, delays, and other effects. The included MIDI Control Center software provides a user interface for MIDI mapping the functions of the controller with the option of archiving favorite presets. The pads can be set for note generation, MIDI CC buttons, and sending program change messages for a wide range of applications. This bundle includes a HPC-A30-MK2 Closed-Back Studio Monitor Headphones offers a solution for experiencing rich and natural sound when listening to music through a mobile device or monitoring a podcast on your computer. These headphones can also be used for DJ work, thanks to the swiveling earcups that let you monitor audio while keeping one ear free.
