Why consider this model?

  • Consider it when a 25-key full-size keybed, eight velocity-sensitive pads, eight knobs and a compact one-fader surface fit a computer-based MIDI routine.

Tradeoffs to weigh

  • The 25-key span and single fader are the smaller sibling's clear limits; the inspected model shows USB computer MIDI rather than direct DIN, and pad-pressure response is unconfirmed.
