I usually make music using Caustic 3 on a Linux machine through Wine however I decided to try out something new and installed HoustonTracker 2 by irrlicht project onto a TI-84 Plus that I own and made two little tunes with it. irrlicht project is much more skilled at using HT2 than I am so don't expect something on par with the incredibly impressive sound example shown on their website.
I hope you enjoy it while I consider about/work on something more full length than this.
