ftgentmp — Generate a score function table from within the orchestra, which is deleted at the end of the note.
Generate a score function table from within the orchestra, which is optionally deleted at the end of the note.
ifno -- either a requested or automatically assigned table number above 100.
ip1 -- the number of the table to be generated or 0 if the number is to be assigned, in which case the table is deleted at the end of the note activation.
ip2dummy -- ignored.
isize -- table size. Corresponds to p3 of the score f statement.
igen -- function table GEN routine. Corresponds to p4 of the score f statement.
iarga, iargb, ... -- function table arguments. Correspond to p5 through pn of the score f statement.

Csound was originally designed to support tables with power of two sizes only. Though this has changed in recent versions (you can use any size by using a negative number), many opcodes will not accept them. |
Here is an example of the ftgentmp opcode. It uses the file ftgentmp.csd.

The output of this csd shows that the tables are destroyed after the instrument instances that created them terminates, causing an init error if the tables are queried.
