OK guys this is for you . if anyone's having problems with the native instruments suites of instruments here's a walk through and a list of recommended controllers to use to run the set up if you're using this semi pro or professionally as I do. Recommended hardware (My setup) CME UF5 through 8 controller keyboard. this is sweet as a nut for midi control and its response is heavenly. it has the advantage of the use of an upg card to add audio handling to the interface. 3 X Behringer BCF 2000 surfaces: used for main mix control and editing of all major parameters 3X Behringer BCR 2000 edit surfaces. these are dedicated for controling several synth and effect parameters. easy to set up recall points and switch between modes all the time. these are my controller specs above so they do the job. now you need to run the standalone instruments to do MIDI learn on certain instruments but most of the time if using sonar with the above controllers, there are profiles automatically designed for native instruments including the b4. so there's no real worry there. I'm able to manipulate what I need straight away. this is either on my laptop with an EMU 1616M soundcard and one of each of the behringer units for demo or mobile recording work. I also have the EMU controller keyboard for the laptop and it does me proud. so if you need any further help and guidance then cool I'd be more than willing. just dont flood me with thousands of emails please. lol lew
