Intuitive, fast, logic…” “Whatever I try, I always come back to BAM to start my tracks. Either to jam live and have fun or to build the basics then export in audio or MIDI and complete in another app.. BAM is versatile enough to allow any musical genre. The team is responsive and helpful in case of questions or issues. I like: intuitive & simple yet powerful UI, built in effects, work with audio loops, export capabilities.” “How did I miss this one? Easy to learn and like nothing else for live jamming. Get two iPads and run this on one and DRAMBO on the other and go wild. Who needs hardware when you can have this much fun for the price of a couple of beers.” “I’ve never clicked with what people call ‘groovebox’ apps but this just made sense to me and I had instant results. The more I use it the more I learn and I realize the possibilities it brings. I’m making some slow, dark, atmospheric stuff with it as well as making quick, rhythmic things. The developers are passionate about what they do and respond to questions quickly. I wrote this a few days after buying BAM and I can’t wait to learn it inside out to fully explore it. I think this app is an absolute bargain considering the amount of work that has gone into it and the features included.” “This app is incredible. The demo tunes alone are well worth it!” “Great app for building whole songs, courtesy of the built-in clip launcher. The developer is very active, and constantly fixing bugs and adding new features, so definitely recommended.” “This app has me excited to make arrangements, jams and tracks on the ipad. Your YouTube tutorials were super helpful. The app is easy to use with powerful tools to have a lot of fun. Really appreciate the work you put into this and all of your apps. We are very fortunate. Thank you. Keep jammin!” “This is literally the type of app I’m looking for, FAR easier to use than most music programs and so far their best work since DRC.”
