The Oxygen 25 IV from M-Audio features not only twenty-five velocity-sensitive full size keys, but also ships with several music software titles that allows for immediate music making. With the additional assignable knobs and pads, the controller provides comprehensive control over the included and other software, facilitating the recording and mixing of music without ever reaching for a mouse -- all the while maintaining a small footprint.
Aside from the velocity-sensitive keys for playing chords, bass lines, and melodies, eight knobs are available for tweaking effects plug-ins and virtual instruments, along with eight velocity-sensitive pads for triggering samples or finger drumming. And for controlling the master output, a single fader is available along with dedicated transport controls and track-up and -down buttons
