Crystal Focus 8 Sound Bank Issue

[Yugi]

So I have completed my Saber with a Crystal Focus 8. When I attempt to change my sound font, it plays the beep noise, then just makes a sound that sounds like a "deactivation" sound or "off" sound. Out of 1 of 10 attempts I again pressed the aux switch twice and i was able to get into the sound bank. Although it worked, it takes me many tries to get to the sound bank using that way. Even when I press it twice within 3 seconds it stay with the same sound font. HELP PLEASE!!!
