Rosegarden for Windows
Ah time. I wish I had some more.
The current version is Rosegarden for Windows 12.04.99 Alpha 3 and is available for download here. It's been tested on Windows 7 and Windows XP and I'd like to hear more about how you're getting on with it. This release has no audio support but you can do pretty much everything else.
Hopefully if there is some spare time in 2013 I'll be able to merge the latest trunk on to the Windows port and think about that audio - however time is at a premium. One thing I am particularly interested in though is adding Kinect and/or Leap support to the MIDI input stream.
If you'd like to help me with the Windows port then please get in touch with me (@xyglo) or drop in on the Rosegarden mailing lists.
