I wasn't sure where to post this since it isn't an issue with the songs themselves, but rather a limitation in Ultrastar DX. While editing a song, I noticed that Ultrastar doesn't appear to have A# as one of the possible notes. Is it just me, or did the creators of the program leave that out?
Use a B flat? :D
I'll try asking them on their IRC channel about that.
Yes, it's B flat.
Since A# is usedway less often than B flat, people tend to replace it, even when everything else is sharp.
In the end it doesn't matter :P
