I have a CME UF5 and I can't find drivers for Windows 7. Power it with the power supply, DON'T connect the USB cable to it, and simply use.

The price of controller keyboards has fallen sharply over the past few years, but whoever thought that we'd see an 88-note weighted-action keyboard with aftertouch for under £500? Enter CME's UF8. There's certainly no shortage of 88-note weighted controllers available for the pianist on the market today. There are also lots of semi-weighted synth-action controllers with spans of 25, 49, 61, or 76 keys, most with mod and pitch wheels, and some with aftertouch.

However, the UF8 keyboard controller from the Beijing-based Central Music Company (CME) is something I've been searching for for several years — a budget MIDI controller with 88 keys and aftertouch. Photo: Mark Ewing Some musicians assume that 88 weighted keys can only be used for playing piano and other percussive sounds, and that they aren't suitable for synth sounds and orchestral instruments. However, I've never been convinced by this argument, especially since many modern Gigastudio libraries require keyspans of 76 or more notes to easily access the keyswitching functions used to move between different articulations. Within reason, weighted keyboards can be extremely useful for playing all instruments, and moreover, not everyone has the space or the money for two controller keyboards. So, why use two keyboards in the studio when you could use one?

Although this new UF range is the first to appear under CME's own name, their patented weighted keyboard action has apparently already appeared in various other companies' products. There are four models in the range.

The UF5, UF6, and UF7 have semi-weighted synth-action keyboards of 49, 61, and 76 keys respectively, while the UF8 being reviewed here has a 88-key weighted hammer-action keyboard. Otherwise, they are identical, except that the UF8 is supplied with a sustain pedal — on the others, this is an optional extra.

All four UF keyboards incorporate several unusual features — the aforementioned channel aftertouch, a breath-control input, the option to retrofit an optional Firewire-based audio interface, plus a largely aluminium case compared with the plastic of some competitors' models. Each has eight rotary controllers, nine sliders, transport controls, pitch and mod wheels, plus sustain and pedal controller inputs. They are also excellent value for money — the UF8, with 88 weighted hammer-action keys is just under £430 in the UK, while the remaining semi-weighted models come in at £270 for the 76-key, £230 for the 61-key, and £170 for the 49-key versions.

The entire range has stylish good looks, and the unusual metallic red end cheeks and rear panel provide lots of character. At 23.5kg the UF8 isn't a lightweight keyboard, although it's still fairly typical of its genre, with M Audio's Keystation Pro 88 at 21.4kg and Oberheim's MC1000 at 20kg. However, those intending to gig on a regular basis should bear this in mind (CME's semi-weighted 76-key version would possibly be more suitable at just 11.8kg). The indented modulation and centre-sprung pitch-bend wheels both have a smooth positive action and are placed to the left of the keyboard for easiest access, while the transport, controller, and editing controls are ranged in groups from left to right across the top, leaving plenty of space for you to rest a computer keyboard on top (as suggested by the top-panel graphics, which mark out the outline of one on the right).

Round the back, there's a standard MIDI Out, the sustain pedal input, footpedal input, breath-control input, a USB port for bi-directional connection to your computer, a power socket, and an On/Off power switch. This last switch is tiny, and the cause of one of my few hardware grumbles — it's simply hard to find and operate. Power for the keyboard can be supplied via the USB connector, but aftertouch and breath control is only available when you plug in the supplied adaptor and power it from the mains supply.
