Info:

Hi everybody...
I am often on the road at university or elsewhere, so i adore portables very much ...i often get inspiration when my desktop isn't at hand, and my laptop fails batery after half an hour (old crappy thing it is)
So I would appresciate a portable Guitar Editor very much, as perhaps do a lot more creative ones
TUXguitar seem convenient, because it is very easy to operate, has almost all necessary functions to compose (compared to GuitarPro, there are some operators missing that make the editing more comfortable) and is OPEN SOURCE...

ADDITONAL INFO:

It needs JAVA Runtime environment and a Sound package, which can both be downloaded for free ... i'm not sure whether JAVA might inflict some problems ...

Is it very dificult to make TUXguitar Portable ?

Thanks for your attention
