I made a song using the latest version of this app!
Unfortunately, the latest version of this app is about half as powerful as it was one or two updates ago. For some reason, the developer cut the number of patterns that each instrument can have in half! The only thing that the update improved was the exporting capability. I'm guessing that the size of the save files was holding back the exporting capability, so he cut the patterns in half to make it work. Still, this is a great app, especially if you like making simple 8bit music!
Here it is, my first track with nanoloop for android (which has the same features than the iphone version). I like this app (even if I miss terribly my ds10 delay), the pattern editor gives more flexibility and I love FM synthesis. Notice that I didn't use samples, read my lips : samples are evil
