Hi there,
I am using Aria Maestosa now since 3 years, and I am very happy! Thank you so much for your amazing software, please don't stop developping it!
However, I noticed a bug when setting a global variable tempo using the editor: when you try to be precise by inputting a specific value (right-click > enter bpm value), the value gets weirdly quantized, eg: you can input 100 and 104, but any value in-between is floored, ie, 101, 102 and 103 gets set to 100. However, if you left click to draw the line by yourself, then the correct value that you pinpoint is set, so the bug affects only the right click option to set a specific value.
NB: when I say quantized, I don't mean in the duration (this is affected by the magnetic grid as described in the doc), but rather "vertical quantization" which is the value of the bpm, which should not be quantized under any circumstance! (and anyway the magnetic grid settings do not affect the "vertical quantization", so this bug seems to have nothing to do with the grid).
Indeed you are right, there was some bad rounding in there. The bug has been fixed in SVN and will appear in next release, thanks! (I do not know when next release will be, however if you need a fixed build quickly just let me know and I can probably upload a quick fix)
