If you own our Chicago Fire collection and use ACID^® Music Studio™ software, then take advantage of these 20 free ACID song project files. We designed these projects to provide quick, convenient scoring options. Score a video clip, use as background music for voiceovers, or even use these projects as song starters. Five distinct themes are available now, with four variations per theme, presented in 15, 30, 45, and 60-second segments. Just open one of these projects in your ACID software, render it out to your desired audio format, and drop it on your timeline for instant, royalty-free, high-quality results. If you want to make the finished product completely unique to your presentation, take advantage of the serious editing tools in ACID software — manipulate key and tempo, add or take away loops, and work with built-in effects. Or, just open the project, render it out, and use it — the choice is yours!
