Rule of thumb is: For i-rate object: square-brackets; for k-rate objects: global variables
For krate objects (graphs, k-rate sliders, toggles and pop-ups), the time-varying values are passed on with the use of global variables in the form: gkname_of_variable. Graphs are also usable through their function tables as numbered in the interface definition. The user can utilize these functions in the orchestra with the usual calls to a function number
