The aim of this project is to build software, which replicates all features of the original Power Tab Editor 1.7, whose development has been discontinued since 2000. An open-source implementation of the core features has been released in 2007. The current re-implementation (from the scratch based on the aforementioned ptparser project) is using the Qt framework to work on all major platforms, i.e. MS Windows, (Mac) OS X, and Linux. Once this step has been taken, missing (and often requested) features will be added, i.e. three-voice, 8-string guitars, and drum tablature.
However, please be aware that it will still take some time until a stable beta will be released to the public. Thank you for your patience!
