|The Single Vol (Shared) block is a volume slider programmed with the slew algorithm. If your DSP model does not support the slew algorithm, use the Single Volume Control (it's direct-write and has the option for the algorithm with no slew). If your DSP does support the slew algorithm, use this block, because it's more powerful. The ability to Add and Grow algorithms is important, especially in applications where multiple DSP boards will be used; this volume control lets you grow a particular algorithm already selected for a DSP.|
The following steps clarify the difference between an added and grown algorithm with two DSPs. Observe that there is no visible difference between a grown and added algorithm on the block itself, and the only indication of different DSP boards is wire color of block connections.
Now the top two pins are associated with the DSP under IC 1, while the bottom pin is associated with the DSP under IC 2. To wire this block to other blocks, you maintain the same DSP association; the software will not let you connect pins from one DSP to another. Observe the different-color traces for the different DSP boards below:
