Demo of Bitwig Studio's digital audio workstation, with touchscreen capability. [Hooktube]
This looks cool and futuristic but:
1. It seems partly about selling Microsoft Surface tablets, which means you have to surrender to Redmond's invasive signup requirements, Windows 10 spyware, and the rest of it, and trust that your tablet will work as advertised in controlling a music synthesizer.
2. Presumably the draw is interactivity in live performance situations. The presenter switches to a mouse at certain points in this demo, so fingering the glass may not always be the best way to work.
