Low profile controller with sequencer command built in.
KeyStep is a new breed of portable musical tool combining the functionalities of a keyboard controller with a polyphonic step sequencer to control both analog and digital devices.
Really useful for people that, like me, travel a lot, plug it into your laptop and play perfectly neat! its small keys does not impact the feels that is really really great. Aftertouch, Arpeggiator and Sequencer add some useful features; also MIDI, USB, CV and Sync connettivity are featured!
I searched high and low for a MIDI keyboard that was 1 - affordable, 2 - was USB powered, and 3 - had MIDI inputs and outputs. This successfully achieved all 3 of those items I wanted in a MIDI keyboard. Some people say it feels "toy-like" (I've heard this in a YouTube review) but I strongly disagree. I think it feels heavy and well built. This is a great bargain.
I have three of these. The keys are not mini keys so if you have big hands and fingers like I do you will not have a problem. Velocity, aftertouch, arp, and a sequencer. What more could you want at that price point?
