Periodically write orchestra control-signal values to a named external file in a specific format.


ifilname - character string(in double quotes, saces ermitted ) denoting the external file name. May either be a full path name with target directory specified or a simple filename to be created within the current directory

iformat - specifies the output data format:

Note that A-law and U-law ouput are not availble,and that all formats except the lsat two are binary. The outpu file contains no header information.

iprd - the period of ksig output i seconds, rounded to the nearest orchestra control period. A value of 0 implies one control period (the enforced minimum), which will create an ouput file sampled at the orchestra control rate.

interp (optional) - if non-zero, and iprd implies more than one control period, interpolate the k- signals between the periodic reads from the external file. The default value is 0 (repeat each signal between frames).


These units allow up to four generated control signal values to be read or saved in a named external file. The file contains no self-defining header information, but is a regularly sampled time series, suitable for later input or analysis. There may be any number of kread units in an instrument or orchestra, and they may read from the same or different files. There may be any number of kdump units in an instrument or orchestra, but each must write to a different file.
