HoustonTracker2

A music editor for TI graphing calculators

About

HoustonTracker 2 is a software sequencer that enables you to create music on Texas Instruments graphing calculators. It uses the machines' communication port to output multi-channel 1-bit music. Its interface is inspired by popular trackers such as LSDJ, Famitracker, and Milkytracker.

HT2 supports several models of the Z80-based line of TI calculators. It is mainly targeted at older, obsolete models like the TI-82, but also works on TI-83, TI-83Plus/SE, and TI-84Plus/SE.

More information and online documentation can be found at http://irrlichtproject.de/houston

Note that the online documentation applies to the stable version of HT2, for the beta version refer to the manual in the /docs folder in source.
