You can copy and paste layer properties. When you copy or paste layer properties, the following values are copied from (or pasted to) the current layer:
High Key and Low Key
Floating Range Up and Floating Range Down
Velocity Min and Velocity Max
Copying and pasting layer properties can greatly simplify creating multiple layers with the same key ranges or velocity values. After pasting, values can be edited as with any layer.
Choose Copy Layer Properties from the Instrument Channel Strip Inspector Action pop-up menu.
Choose Paste Layer Properties from the Instrument Channel Strip Inspector Action pop-up menu.
