Midiman's undeniably cute Oxygen8 combines both approaches it's a neat, two-octave keyboard with velocity-sensitive full-sized keys, pitch-bend and mod wheels, along with eight assignable rotary MIDI controller knobs, and an additional socket to plug in a sustain pedal. Evolution have also released their MK249C USB, which has a very similar specification. This has a four-octave keyboard and a dozen assignable rotary controls. Miditech were the first to meet the obvious demand for a low-cost keyboard with built-in MIDI controllers with their Midicontrol (reviewed in SOS December 2001).

Meanwhile, anyone who wanted more hands-on control of their various hardware and software synths would look at a dedicated controller featuring either sliders or rotary knobs. Until recently, however, keyboard-oriented MIDI studio owners with limited space often had to resort to using keyboard controllers with miniature keys. For applications where space or portability are at a premium, it is hard to beat this compact, two-octave MIDI master keyboard, which also incorporates eight assignable real-time MIDI controllers.ĭedicated master keyboard controllers have been available for years, with spans ranging from four to seven octaves, and with a variety of feels from lightweight synth to weighted hammer action.
