Okay, still operating on the demo of FL studios, so I made this little shorty in a couple of hours. It's a really short loop, with somewhat of an 8-bit tone (the only sound that you hear changing is actually a saxophone from a sampler.) And Even though only one thing changes, it's still pretty tense. Best used for a short time, like a dialogue.
Please contact me if you would like to use this in a project. We can discuss the details.
