This program lets you use your calculator as a USB MIDI keyboard. The program can be installed on any TI eZ80 calculators, which includes the TI-84 Plus CE, 83 Premium CE, and 82 Advanced Edition Python (along with other 84 and 83 color-screen variants such as the 84 Plus CE-T). It should work (no extra programs / drivers necessary) with any devices that allow USB MIDI input.
- Download the latest version from the GitHub releases page.
- Send MIDICE.8xp to your calculator using TI-Connect CE or another linking software of your choice. If you don't have the CE C libraries, you'll need to download and send those as well.
- Run prgmMIDICE from the programs menu (You will need to use the arTIfiCE jailbreak if you are on an OS version 5.5 and above or are using the TI-82 AEP).
In order to use the program, you will need to connect your calculator to a device that can receive USB MIDI input. You can use the same USB cable that you used to transfer the program earlier.
