After many hours of trying I think I am totally stuck with trying to get my new Focusrite Scarlett 18i8 to work with Cubase 7 or 8 on a Mac (El Capitan). Simply there is no in/out sound or signal and occasionally just “Recording error: driver is not running”. When recording no data is being written, when listening none of the outputs show life. Mixer Control software for Focusrite gives signal and works but there is no connection with Daw. I’ve tried updating all software, drivers, firmware, even tried the beta driver, changing buffer etc. Cubase sees the device, I can setup connections but doesn’t look like it’s really using the driver. It just wont work. Scarlett works on it’s own or with other daws fine. It seems just bit unusual that there is no official information about this problem and no support especially considering Focusrite is popular brand and a quality one. I am out of ideas, please help I can’t return the product!
