From dsp macro /usr/lib/dsp/ugsrc/scl1add2.asm (see source for details) 00007 00008 You instantiate a subclass of the form Scl1add2UG<a><b><c>, where 00009 <a> = space of output 00010 <b> = space of input1 00011 <c> = space of input2 00012 00013 The scl1add2 unit-generator multiplies the first input by a 00014 scale factor, and adds it to the second input signal to produce a 00015 third. The output vector can be the same as an input vector. 00016 Faster if space of input1 is not the same as the space of input2. 00017 00018 Original Author: David A.
