Assigning Template
Templates are predefined arrangements of slide cells and 3d instruments.
The chosen templates dictates the 3D instrument for that slide: keyboard, guitar or bass.
They are only a starting point as slides can be edited almost infinitely. Also, you may change template and/or 3D instrument by running the Slide panel again.
To select a template simply click on it. A blue frame appears around the selected entry and the title becomes green to signal a change.
The 3D instruments are shared between slides. This way a new 3D instrument is only created if no other slides have used it before.
