The Noise app is very limited and it has only 4 tracks and only 1 out of them is for drums.
it can be improved a lot like very basic GarageBand to support multiple tracks and instruments and bar lengths more than 8 bars.
The power of Noise app is its support for SWAM instruments and a lot of other good sounds but it's very less productive in terms of speed and ease of use.
Though Seaboard and Lightpad are very creative products and have a lot of potentials, I am not able to use them easily because of the App's limitation.
I use Apple iPad for my production and I am not finding the Blocks very helpful because of productivity issues.
If you can improve the app that will be great.
