Oberheim OB-XK 61 Key 80's MIDI Keyboard Controller 

The Oberheim OB-Xk is a MIDI keyboard controller from the mid-eighties. Originally designed to control the Matrix and Xpander modules, it uses MIDI and works fine as a controller for any MIDI gear. It's got 61 keys that respond to velocity and aftertouch, two OB-style Pitch/Mod controllers, and one assignable continuous control slider. From the front panel you can directly access the first 100 single patches and/or 100 multi patches of your MIDI module. Any additional patches must be selected by another MIDI controller.

Other features include the ability to transpose up or down by up to 2 octaves or by half steps. The keyboard can be split into 3 zones. There are basic Hold and Chord memory functions and an Arpeggiator section with pretty decent features (it can use internal or external clock). The OB-Xk can also send a sequencer Song Select, Start and Stop commands. It's built with Oberheim's classic & vintage look: solid black metal case with wood end-cheeks. (Vintage Synth Explorer)

Please note, this is a MIDI controller, not a synthesiser or digital piano. It does not produce its own sounds.
