What are the softwares on your notebook that you use to produce music?

[Trancesition]

I read in an article that while you were in Japan, you were creating music on the move with your notebook while on a train to Kyoto (hence the track Kyoto because you saw Mt Fuji and it was so beautiful).

Just curious, want to know what notebook do you use and what software to you utilize to make tracks. The specs, the software, the works, everything! :)

Thanks!
