Hi Chris, There has been a noticeable improvement, but not dramatic. I found something new scenarios for you to consider...
TEST1: Nine tracks with patterns all playing to different channels from #1 to #9 on the same external instrument. CPU 40% (rosegarden meter). That seems okay. TEST2: Nine tracks with patterns all playing to the same channel #1 on the same external instrument. CPU 75% (rosegarden meter). Why is this so much higher than Test1? Merging the Midi? TEST3: Similar to TEST2 in that all 9 tracks are on the same device/instrument channel #1. However, all are empty except for first track which has a pattern. Play it and the CPU will be much higher than if only the 1st track plays on that channel. CPU Averages 40-50% (rosergarden meter). If only the first track is assigned to channel #1 then CPU is low at less than 20%. This is the strangest one to me. Something about being on the same channel? All the blinking meters on empty tracks? My original examples that made me notice this had a few blank tracks that were assigned the same channel as other tracks with patterns. Otherwise, looking at "top" while playing my example large file.. - Xorg has gone down somewhat about 5% to 10%. this is the most noticeable change. - There seems to be a little more improvement in safe mode compared with fast - using $ rosegarden -graphicssystem opengl it does more than it did a few days ago but crashes upon loading projects or playing.
