This is a Like New Arturia Keystep Midi Controller and Sequencer. Have only owned for a few months. Has never left the house. Comes with original packaging and papers. It's very similar to the Arturia Beatstep in that it can sequence both Midi and Analog Synths and Drums. Has the extra awesomeness in having a traditional keyboard as well. Works great. Doing some spring cleaning. Thanks for looking!
