Which version of LilyPond are you using? The 2.13 series has many, many improvements in font/text handling that may not have been backported to 2.12. I tried this on 2.12.3-1 (MacOS 10.6) and 2.13.47 (MacOS 10.6). I see the same problem in both versions. -Samir

As Jay pointed out, \times 2/3 {d8 g a } will occupy the time of two eighth-notes, not three. Hence the barcheck fails because there is an eighth-note's worth of time remaining in your first measure (and 2 1/8's missing in the second.) Cheers, Mike On Sat, Jan 29, 2011 at 3:01 PM, Martin
