It can play up to 64 sounds, as soon as you apply Redstone (or rightclick with the mobile one), at a rate of 1 Sound per 1/10sec. So compose your Songs by just clicking around in a GUI. It loops the Sound as long as Redstone is applied, so you don't need a Timer.
The mobile Sonictron can store the Data of the Sonictronblock by just rightclicking the Sonictronblock.

It is crafted as follows:
