ACE Step is an open AI model that creates music from simple tags. You describe a genre, mood, or instruments and it makes a song. It also supports many languages and lets you add lyrics. The cost is very low, just a fraction of a cent per second.
You can use ACE Step to generate new music, fix a specific part of a track, or extend a song forward or backward. All of this works through the RunComfy command line tool. It is fast and affordable for content creators, musicians, and developers.
