After creating a NeoTrellis soundboard of nature sounds, I thought it would be fun if we could mix the sounds together. So first I adapted John Parks’ Eight-Step Drummer to be four-step with 8 sounds. Then I modded the code to use my nature sounds and slowed the tempo so that you could hear them better.

All the sounds are the National Park Service and in the public domain. You can download my edited sound files at http://bit.ly/2FssIGh
