Start Playing

You can start building from scratch on an empty grid, or use one of the prebuilt examples as a starting point. Take a look at the short quickstart guide below, to get an impression how GridComposer works. Check the manual to get a complete overview of the functionality.

Send Midi Output

From a quick test, it looks like a perfect app for those into minimalism (think Steve Reich playing with an iPad). Sure, I wish to see a more full featured MIDI section, more instruments and Ableton Link support in the next updates, but even as it is, the app is really well-designed (I loved the fact that you can change scale and key on the fly) and deserves your attention.
