Connecting Midi Controller To Soundcard MIDI Controller: Should I Connect Via USB Or MIDI?

MIDI Controller: should I connect via USB or MIDI? - connecting midi controller to soundcard

I've recently bought an M-Audio Keystation 61es MIDI controller for use with Reason 3.0. The reason why I'm running on an old computer that I use for something else. Finally, connected to the controller via the USB cable that came with it and I have almost a second delay between pressing a button and heard a noise! My sound card is a Creative Sound Blaster PCI () various years.

So here's the deal delay: I read in another post replies fits over the USB-MIDI instead of a real. What must I do to eliminate this delay? Get a new sound card with a USB or MIDI-in?
