Dachay, could you explain it for me??.
As AlChuck said, it stands for DirectX Instrument. A DXi allows you to playback midi using software rather than hardware - so it doesn't matter what sound card you have, or whether you have an external synthesizer.
There are a couple bundled with Sonar (including a demo of Live Synth Pro, which allows you to use Sound Fonts without have a Creative sound card). The one you want to use for this is the Virtual Sound Canvas (VSC).
It's actually pretty easy to use.
First go to View -> Toolbars and make sure the Views toolbar is selected. On the Views toolbar you will see an icon for DXi. Select it and a window will open. Click on the icon to the far left on this window (looks like a star) and choose Edirol VSC. On the popup window, select Midi Source Track and First Synth Output and click OK.
This will insert two tracks into your project - one midi and one audio (both will be labeled Edirol VSC - you can rename them if you want). On the Midi track click the down arrow next to Channel (Ch) and choose channel 10, then click the down arrows next to Bank and Patch and choose Drumset and then whatever set you want to use.
Open the Piano Roll View for the midi track and draw in 4 quarter note beats using whatever percussion device you want to use for your click. As I said, I use a cross stick, but you can use a cowbell, snare, tamborene or whatever you want.
Close PRV, copy and paste the measure you just created to the remainder of the Midi track.
Click the play button.
It should now playback through your Delta card.
