The 49 or 61 note velocity sensitive keyboard is a synth action with a medium tension. The full-size, piano-style keys are covered to protect against dirt and dust while also complementing the Impact LX design. With 4 velocity curves gradually increasing in dynamics there is a choice for any playing style. If you don't need velocity, 3 fixed velocity levels cater for a consistent output. Octave and transpose buttons as well as pitch bend and modulation wheels are within reach, so you can quickly shift the keyboard up or down as needed, or apply additional articulation with the wheels. Impact LX49 and LX61 software integration supports most of the popular DAWs. A common workflow gives access to many of the functions you are most likely to need when recording and performing with your Impact LX . The best part is that it's all done for you: Simply complete the installation process and start making music! Impact LX DAW integration currently supports Cubase, Digital Performer, FL Studio, Garageband, Logic, Nuendo, Reaper, Reason, Sonar and Studio One. Buttons and controls are labeled so you don't have to remember how they are assigned. Thatâ€™s why Impact LX is a breeze to use but with enough extra features under the hood to challenge even the most experienced power user.
