I have the soundcard that came with the p.c completly disabled and i use my tascam us-428 as my soundcard. The 428 is a DAW control surface as well as a 8 tracc 24 bit mixer and midi interface. The 428 does not have any midi thru's but it has two in's and two out's. The cubase sx manual said i had to have that box that said midi active thru. Within cubase i can record audio traccs and play them bacc and they sound great. But when it comes to midi i just cant control the vst instruments that i have like Halion, Modle E or any of the others. If i run the mk-6 into a midi tracc by itself as the sound source it works fine but using it to controll the vst's just dont work. I picced up about $300.00 worth of books and video's on Midi and DAW"s so im sure i'll get it sooner or later. MR D-Sane i have read several of your posts and i would like to thank you for taking time out to drop some knowledge on the rest of us. Your knowledge has helped out more then you will ever know. I would like to learn to read and write music and play the piano could you suggest any good books or video's that will help me out. I learn better by watching video's so if you know of any it would surely help. By the way imma get at you in the next couple months to buy some beats from you.
