Er zijn zeker wel Drivers voor de UC33 te vinden. Hieronder een stukje uit SoS
Suitable USB drivers are supplied for Mac OS 9.x, X, 10.2, and Windows 98, ME, 2000, and XP, although since all Evolution controllers are 'class-compliant', OS X and XP users can instead use their native drivers.
However, the Evolution drivers provide the great advantage of being multi-client. When working with the presets I found this very useful in conjunction with the MIDIOX utility, since I could monitor the UC33's MIDI output while editing software synths in another application. The Evolution drivers also support up to 10 Evolution USB MIDI products, including further UC33s, UC16s, and keyboards.
Using the USB drivers also makes your computer 'see' the UC33 as two MIDI input devices — the first for the controller information, while the second passes on data from any device plugged into the UC33's back-panel five-pin MIDI In port. While some other controllers like Kenton's Control Freak provide a MIDI merge function, which makes it easy to plug in a keyboard and end up with combined key/controller output data, in practice most modern MIDI sequencers offer software MIDI merge facilities from multiple inputs, so the UC33 approach shouldn't prove a disadvantage unless you're using it away from a computer. Moreover, on some sequencers, like Cubase VST for instance, allocating a particular MIDI input for automation purposes prevents its data being recorded to a track.
There's also a 'MIDI Out from USB' mode switch combination on the front panel. When activated, this disconnects controller data from the back-panel MIDI Out socket, and instead forwards data from the UC33 USB MIDI Out that you'll find in the list of devices on your computer. Effectively the UC33 functions as a one-in/one-out MIDI interface as well as a controller when using the USB connection, from which it also takes its power.
I had no problems with the two-stage Windows XP driver installation (the USB driver, and then the MIDI driver), but there is one XP peculiarity not mentioned in the manual. If you subsequently plug in another Evolution device such as a UC16 or MK225C, it will be grabbed by the standard XP drivers and simply appear as a USB Composite device. To make it visible to the Evolution drivers, you need to right-click on this in Device Manager, select the 'Update Driver' option, and then point to the existing Evolution drivers, when it will correctly appear as UC16 (or MK225C) USB MIDI In and Out.
