In 2005, CME released the first of the UF series full-function Master Keyboards, which became an instant classic as the most convenient and cost-effective full-function master keyboard in the world. CME’s new UF family of controller keyboards is comprised of four different models. The UF50, UF60 and UF70 feature ‘semi-weighted’ keyboards with 49, 61 and 76 keys respectively, offering velocity sensitivity and aftertouch. The UF80, unsurprisingly, is the largest and heaviest of the bunch, measuring 1408 x 372 x 150mm and weighing in at a daunting 23.5kg. Eight assignable knobs and nine sliders of course, one of six key pad sequencer (rec, stop, play, FFW, RWD, back to top) plus a list of all shortcuts directly on the keyboard.
According to several user reviews, they have praised CME UF80 for the very solid construction; Comfortable, playable keyboard; Wireless MIDI; ‘U-CTRL’ Mackie Control surface emulation. Also, some users have complained it for the documentation is poor and incomplete; Occasional mechanical keyboard noise; U-CTRL may not work wirelessly.
