Hi there, I bought a CMD Studio 4a a month ago. So excited at the beginning: [INDENT]1. Very sturdy; 2. Metal finish; 3. Beautiful lights colors (my daughter is so excited about this); 4. Well build knobs and faders; 5. Great job with "kill" buttons; 6. Awesome jogs; 7. All the elements are very friendly; 8. Mapping made easy.[/INDENT] but: [INDENT]1. The faders paint went off after two uses; 2. Deckadance software: [INDENT]a.) Does not recognize the CMD Studio 4a with the Behringer ASIO Driver but works OK with ASIO4ALL (OK, not like a charm); b.) big latencies on faders when trying to scratch or play with faders; c.) from time to time the music stops for less than a second (encountered this problem on VDJ too) / some glitches;[/INDENT][/INDENT] I did some diggings and found that many people have changed the USB cable and the problem disappear. Not to me. I've changed 7 USB cables and the glitch doesn't leave (perhaps he loves living with me.. but I hate it). I have to mention that my laptop is an HP450 i7 2.2GHz / 16Gb RAM / 1Tb HDD 5400rpm. Any suggestion on how to optimize? Btw, for future builds of this controller I take the opportunity to suggest: [INDENT]1. Channel GAIN knob; 2. CUE buttons to be used like normal pads / the possibility to be reconfigured.[/INDENT] Thanks for your time and support. Have a grateful day!
