tival
Puts the value of the instrument's internal “tie-in” flag into the named i-rate variable.
Syntax
Initialization
Puts the value of the instrument's internal “tie-in” flag into the named i-rate variable. Assigns 1 if this note has been “tied” onto a previously held note (see i statement); assigns 0 if no tie actually took place. (See also tigoto.)
Examples
Here is an example of the tival opcode. It uses the file tival.csd.
