subinstr — Creates and runs a numbered instrument instance.
a1, [...] [, a8] subinstr instrnum [, p4] [, p5] [...]
a1, [...] [, a8] subinstr "insname" [, p4] [, p5] [...]
instrnum -- Number of the instrument to be called.
“insname” -- A string (in double-quotes) representing a named instrument.
For more information about specifying input and output interfaces, see Calling an Instrument within an Instrument.
a1, ..., a8 -- The audio output from the called instrument. This is generated using the signal output opcodes.
p4, p5, ... -- Additional input values the are mapped to the called instrument p-fields, starting with p4.
The called instrument's p2 and p3 values will be identical to the host instrument's values. While the host instrument can control its own duration, any such attempts inside the called instrument will most likely have no effect.
Here is an example of the subinstr opcode. It uses the file subinstr.csd.
