Good afternoon! First, the particulars - I'm using a widows 10 machine and Song Manager v 1.2.9 Say, I wanted to add dynamic difficulty to this song "Roads to Madness" by Queensryche. I'm afraid it may be too long? Is this a known issue? The song is just over 9 minutes long. This is the error: Maximum playable arrangement limit? Anyway, I double checked on another shorter song and adding the DD works. Like a charm actually. It's pretty frickin cool. Thanks guys!
