I'm trying out Luna prerelease 1 on a Windows 2000 1GHz machine with 512M RAM, and I'm getting a very high CPU usage (e.g., 60-100%) when running one player using a MIDI keyboard (e.g. Crystal or String Theory). Also, I'm getting a lot of hanging notes, for which I have to hit the MIDI panic. I can't quite figure out how to reproduce them though; it seems a bit like if I play sort of fast, or do something like change the preset I'm using, I can "confuse" it.
Also, regarding the MIDI keyboard, I've found that if I boot up Luna, then it often doesn't "see" the keyboard (i.e., it doesn't respond to notes) until after I've pulled up the MIDI setup dialog, even if I had already set up the keyboard in a previous Luna session.
CPU usage and hanging notes and seeing the MIDI device

Crystal is rather cpu-intensive. And a 1GHz machine is not that powerful, certainly if you're banging the keyboard, and so maybe causing many sustaining/releasing notes.fycfung wrote:I'm trying out Luna prerelease 1 on a Windows 2000 1GHz machine with 512M RAM, and I'm getting a very high CPU usage (e.g., 60-100%) when running one player using a MIDI keyboard (e.g. Crystal or String Theory).

So i suppose you're making that cpu sweat too much.
Could it be that you had another application running that took the midi device?Also, regarding the MIDI keyboard, I've found that if I boot up Luna, then it often doesn't "see" the keyboard (i.e., it doesn't respond to notes) until after I've pulled up the MIDI setup dialog, even if I had already set up the keyboard in a previous Luna session.
