Hi Gordon, Hi use a MAudio Profire 2626 soundcard. by firewire. The latency problem is even with dimension Pro, Rapture or EZ Drummer. As with guitar rigg 3. My midi arranger is connect by USB. But, even playing or recording with my guitar connect to a input straight to the soundcard, Guitar Rigg 3, as a bit of delay. I cant play, or record with eco input. I've tryed with asio drivers but, the same happens. I made a hotspot set to the Profire 2626 interface, to access the buffer size. now, i been changing the parameters by 64, 128, etc. On Sonar, the same thing. when recording i put the buffer size, close to zero. Am i missing something? best wishes, Rui Sorry my inglish.

Also, what soft synth are you triggering from your keyboard?

It is better to input the keyboard by a USB cable, or by MIDI cable directly to the soundcard? My soundecard buffersize is around 64. And, on Sonar, 3%.But, there is latency problems. Just a bit,but can't play in time without delay. best wishes, Rui
