Blue cursorline faster than musicsounds
Excuses (in anticipation) for my bad (Dutch-school)-English.
For several weeks now, I face a strange and nasty phenomenon.
Using MS 1.3 on my (2005)PC with Windows XPHome.
Lots of free space on the HDD.
Score A: (home-made for concert band).
Size 6/8, 186 measures, chosen speed 180 bpm ( = beats per minute ).
Having started "playback" , the blue cursor-line reaches the final measure after 3'07'' ( = 187 seconds).
Having started "playback" , the score-sounds reach the final measure after 3'39'' ( = 219 seconds).
To me the music-sounds seem to take 20,8% more time than the blue cursorline, or,
to me the blue cursorline seems to run 17,8% faster than the real sounds.
Score B: (home made too for general purpose).
Size 4/4, 51 measures, chosen speed 60 bpm.
Blue cursor-line finishes after 188 seconds, playback sounds finish after 236 seconds.
(By the way: 1 measure = 4 beats, so 51 x 4 = 204 beats and 204/60 = 3,4 minutes = 228 seconds ........... ??????????)
Discrepancies are either (56/1.88) 29,8% or (56/2.36) 23,7% !!!!
Score C: (general purpose).
Size 4/4, 102 measures, chosen speed 80 bpm.
Blue cursor-line finishes after 310 sec., playback sounds finish after 371 sec.
( 1 measure = 4 beats, 102 x 4 = 408 beats, 408/80 = 5,1 minutes = 306 seconds ............................... ??????????)
Discrepancies are either (61/3.10) 19,7% or (61/3.71) 16,4% !!!!
Is there anybody, who can explain to me this very strange and nasty phenomenon?
("Nasty", especially when I try to use reading en listening -at the same time- to scores for my various pupils .....)
Is there any explanation for the fact, that 60 bpm are not taking 60 seconds ?????
Why is 120 bpm something else than 120 beats of a real metronome????
I already have been putting my odd experiences on the Dutch Forum, but mr. Thomas Bonte asked me to use this one too, although he knows (for sure) that I am a Dutchman.
So again, I apologise for language-, grammatical and idiom-mistakes.
In case of answering my questions or helping me in some other way, please use simple words en simple sentences.
(I'm a real Dutch musician and music-teacher, not an interpreter).
Lots of thanks for paying attention !
