What is the weirdest or most unusual sound you created and used in a song? Maybe you could post a link to the song itself along with a description of what you are referring to. I assume most chip musicians create their own sounds most of the time.
Mine would have to be the bassline in this project: https://soundcloud.com/q-b/unconditional-love-wip
My best friend said it sounded like a tractor engine lol. It kinda does sound like an engine except that the pitch is lower in the sound I made. It's just a tweaked percussion instrument sample.
I like incorporating unusual sounds in my music. There are so many nice sounds around us, for example the sound of the fan(s) in my computer has a soothing characteristic. It would work well in an ambient song.
