I'm using Nokia PC Composer from PC Suite 4. I've found that the program doesn't always play a minim(half note - the white note with a vertical line) accurately when there are several quavers (eighth notes - black notes with vertical lines and tails) immediately before it... noticeably when all of the notes are at the same pitch. The white note should be the equivalent in length to four of the quavers... but sometimes it's only held for the value of 3 quavers. Is there a solution to this problem, other than adding a quaver rest after the white note to put everything back in sync? Your advice would be very helpful.
