Sound Squares is a universal app and I’ve been using it on both my iPad and iPhone for a little while.
I’ve really got into it for the same reason I like many other noise making apps. However, Sound Squares is more than that. In some ways it makes me thing of Bebot although it has a very different interface to it.
The concept is very simple. The screen is divided into a series of squares with each one being editable to a given pitch and waveform. You have control of a good amount of parameters per square and can set up each one to do what you want. In addition there are a range of effects which work on the output of all the squares.
I can imagine using it live, and of course you could set it up to play exactly how you wanted as each square can be edited.
I think it would be really good if you could save your edited set of squares and recall them for different tracks in a performance possibly, but aside from that I think it is really good as it is.
It is one of those app where I’m not sure I would want any kind of record and export function as it is really geared up for just playing, but if you disagree then let me know.
