Public bug reported: In rosegarden (Jack & timidity) I have a bad delay of about 200ms when I press a Key till it sounds through my speakers. I use a YMF-Soundcard with a Yamaha-XG-Wavetable on it. If I use my Keyboard in LMMS the sounds appear just in time. So I knew that it is a problem with the Midi-Out-Device. As workaround I installed timidity++ additional to the existing one and loaded a GM-soundfont into it. Ans surprise: It works!?! So, there is something wrong with the standard-configuration of the midi-out-device in ubuntu-Studio 8.04.
