Earlier this year Christian Gwiozda released an experimental sequencer called GridComposer, which I ignored because although it looked fun it didn't have a lot of use without Core MIDI, nor Audiobus. Today's update corrects both of those oversights! The Core MIDI is going to come in especially handy on this one, because as a sequencer it really is quite fun and now you can use it to sequence other apps!
I'm not as fond of the built-in sounds, but even they can sound good with some added Audiobus effects!

"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."
What's New in Version 1.1
