So sw1000 is supposed to handle 6 stereo tracks by itself, freeing then some CPU, isn´t it??
Well, when I active the different busses in Cubase, the CPU in use increases dangerously, more than if i active just an only bus ( so i cannot take advantage of this cool feature of the sound card and put the effects to diffent parts or tracks of audio).
I got a P350 and i´m using about 10 mono audio tracks and 16 midi tracks with changing sysex information along them but the souncard is supposed to handle this without problems so...why does it take more CPU if i use all the 6 stereo outs than if i use only one??
