The DA-2496's MIDI interface usually transfers MIDI data in less than one millisecond. If there is a considerable delay, it could be because of another device in the system, or an audio buffer that is set too high. Try reducing the DA-2496's audio buffer.
It takes a minimum of 10 milliseconds for the human ear to detect a delay.
