Advanced Song Editor Features

1. Nested patterns. The ability to select a set of blocks and save the set as a single block would enable complex patterns to be more easily managed. 2. Block transpose. A facility to transpose a whole block or set of blocks. 3. Zoom. Ability to zoom-in to facilitate easier positioning of blocks for more complex rhythms. 4. Playback control. Ability to move the playback position to any point while playing. 5. Loop control. Ability to specify multiple loops, each with their own marker pairs. Also, loop counters. Possibly also a scripting language to control looping and other flow of control. Loop count of 1 would allow for a non-looped section.
