Medium Rare releases Step Sequence for iPad

As submitted by Brian Maniotakis at Medium Rare:

Step Sequence is a simple, free iPad app to create looping melodies with notes controlled by a grid of squares.

Tapping on an idle square will enable the note, and tapping on it again will disable it. You can also drag your finger across a group of squares to enable multiple notes. Once you’re done, shake the iPad to reset the entire grid.
