tigoto — Transfer control at i-time when a new note is being tied onto a previously held note


Similar to igoto but effective only during an i-time pass at which a new note is being tied onto a previously held note. (See i Statement) It does not work when a tie has not taken place. Allows an instrument to skip initialization of units according to whether a proposed tie was in fact successful. (See also tival).


tigoto label

where label is in the same instrument block and is not an expression.


Here is an example of the tigoto opcode. It uses the file tigoto.csd.
