A new Finnish music app that passed the "woah check this out" test in the office is Cotracks, a collaborative music iPad app released today. We've all seen beatboxing or music creation apps, but Cotracks maximizes the iPad's real estate for realtime collaborative music creation with up to four friends.
It could be complete chaos, but Cotracks is designed to make it easy to record and playback in sync, which is important when up to four people are riffing on the same beat. As you can see in the video, Cotracks lets you copy your friends' beats to add new things to them, and lets you find a common tempo.
Right now if you want to collaborate in real time to brainstorm a beat, it requires hooking up your laptops, which can be a hassle. "When we first learnt that these touch devices can handle lots of simultaneous touches and process realtime audio at the same time, it became obvious that something like Cotracks must be developed," says Matti Jokipii, creator of Cotracks.
