 # What is LittleGPTracker?
-[*LittleGPTracker*](http://www.10pm.org/nostromo/lgpt/) *(a.k.a piggy tracker) is a sample based tracker originally programed for the gamepark handhelds and PSP but now also available for Microsoft Windows and ~~Mac OSX~~. It implements a user interface similar to the refined track-by-joypad software* [*littlesounddj*](http://www.littlesounddj.com/)*. Piggy currently supports 8 monophonic 8Bit/16Bit/44.1Khz stereo channels as well as 16 channel midi output. Piggy is currently under development and the latest versions of the program (along with beta builds) can be found at* [*https://github.com/djdiskmachine/LittleGPTracker/releases/*](https://github.com/djdiskmachine/LittleGPTracker/releases/)*.*
