To the Rosegarden developers:
(http://www.all-day-breakfast.com/rosegarden/)

Today I convinced my sister to try Rosegarden-4 on Mandrake Linux.
To her surprise, everything worked right after installation.

She connected the MIDI keyboard to the SB Audigy soundcard.
After loading soundfont with sfxload, she played a VGM (FF X) score with the MIDI keyboard, and Rosegarden recorded perfectly what she just played!

Now she can work on composing her songs without booting back into Windows.

Here, I just want to say:

You guys rock! My deep gratitude and thank you to you all.
It is fine work such as yours that makes open source and Linux meaningful.
