$100 · M Audio Keystation 61ES

Like new, has had only light use in my home studio. Just upgraded to a Yamaha The M-Audio Keystation 61es is a 61-note USB keyboard with velocity-sensitive, semi-weighted keys that will easily integrate into any computer music environment... A quality keyboard controller The M-Audio Keystation 61es has 61 keys that are semi-weighted to provide the ideal balance between a resistant "piano" feel and a springy "synth" keyboard. This makes the Keystation 61es a great choice for keyboard classes and multi-purpose music labs that handle a variety of different music courses every day. Plus, its compact size makes the Keystation 61es perfect for use at a computer workstation! Pitch, modulation and other control sources To the left of the Keystation 61es keyboard are a pitch and a modulation wheel for control of these essential synth and MIDI parameters. The volume slider offers a bonus - it can be assigned to control any other MIDI value! Use it to add expression or perform a filter sweep while you record a sequence. In addition, two advanced function buttons can be used to assign other MIDI messages. USB power for convenience The Keystation 61es runs on USB bus power when connected to your computer. That means you don't need anything but a USB cable for both power and MIDI transmission! For standalone use, an optional 9 volt DC power adapter is available. Flexible enough to use as a standalone controller! You don't need to limit the Keystation 61es to computer use. Its MIDI Out port means you can use it onstage to control rackmount synth modules or other gear. All you need is the optional 9 volt DC power adapter! https://www.youtube.com/watch?v=rwXDbD-UrnA
