barcheck fail: note crosses barline

[suntong]

Please take a look at the change of https://github.com/suntong/jianpu/commit/2e42ae6561e001ec1c719b2ef76b4af693a8b4f0

for the song of
https://github.com/suntong/jianpu/blob/master/mmd-木棉道.png

That extra leading 4/4,4 is causing the following error for me:

Error: (notesHad=5 5 6 5 3 2 3 3 2 1 2 3 2 1 6 6 6 1 3 2 - 2 0 5 5 6 5 3 2 3 3 2 1 2 3 2 1 6 3 2 3 2 1 - 1 0 1 2 1 7 6 5 6 6 5 3 3 3 4 4) barcheck fail: note crosses barline at "4" with 1 beams (12 skipped from 60 to 72, bypassing 64), scoreNo=1 barNo=11 (but the error could be earlier)

I'm wondering what the above error actually means, and why removing the leading 4/4,4 fixed the problem. thx.

Hi, it's because the ,4 part of 4/4,4 means there's a 弱起拍 (anacrusis, pick-up) before the start, but 《木棉道》 has no 弱起拍 before the start.

Please may I ask, did you read something in the instructions that made you think you had to write 4/4,4 at the start of 《木棉道》? Can you remember exactly what you read that made you think you had to do this? so I can fix it :) thanks

Oh, I got it!!

The following of the two songs has such 4/4,4

• https://github.com/suntong/jianpu/blob/master/Friends-朋友.jp
• https://github.com/suntong/jianpu/blob/master/yxdcb-隱形的翅膀.jp

and I wasn't sure why until seeing your kind explanation.

I totally get it now. Thanks a lot!
