Locate the Creative Surround Mixer icon and click on it or open it from the Start... All Programs menu, probably in a folder labeled "Creative" and then a folder named for your sound card. Click on the MIDI volume slider and slide it up to 100%. Be sure the Mute button is not on. Click the red plus (+) sign above the MIDI volume slider to enable the Advanced Controls.

Check MIDI Chorus and MIDI Reverb on the Advanced Controls panel to enable these effects. Click OK.

Click the button to the right of Default to open the EAX Console.

Be sure Enable Audio Effects is checked. Select an environment such as Concert Hall from the box. The environment you finally select is a matter of your own taste and how things sound in your installation.

To evaluate the amount of reverb and test the sound font installation, use the on screen keyboard of the SoundFont Bank Manager. Select bank 025 from the Bank dropdown box. Select an organ voice from the Instrument dropdown box. You can play the keyboard with the mouse or the asdfgh row of the computer keyboard for naturals and the qwerty row for accidentals.
Close the SoundFont Bank Manger and the Creative Surround Mixer. You are now ready to configure the Miditzer to use sound fonts.
