Dynamic DSP
We’ve offered up a whole lot of sound possibilities in POD HD, and it can take some
serious Digital Signal Processing (DSP) to run these goodies. Rather than limit your
creative potential with fewer Models or signal routing options, we chose to implement a
“Dynamic DSP” system, which dynamically assigns DSP resources to accommodate your
tone configurations. When creating a tone that utilizes several heavy-hitting DSP Models,
it is possible to surpass the amount of processing power available. In these cases, you’ll see
the DSP LIMIT REACHED indicator appear, and the current Model is bypassed to allow
your tone to remain active.

In the above example, trying to change the Model for a 2nd Amp placed our tone over
the DSP limit. Therefore, the DSP LIMIT REACHED message is shown temporarily, and
the Amp B Model we selected is automatically bypassed, as indicated by the DSP Over
message. When the DSP Limit is reached, you have a few options to free up DSP resources.
• Try using different Amp Models. Some of the HD Amp Models require more DSP
power than others, so try switching to a different Amp Model.
• Use only one Amp Model rather than two.
• Try toggling Amp and/or FX Models “Off” or set the Block’s Model to “None,” (see
“FX Blocks” on page 3•1). Some FX types, such as Pitch Shifters and Reverbs, utilize
DSP more heavily.
Note: Setting an Amp or FX Block to “None” more substantially reduces the Block’s DSP
usage than toggling its Model to “Off.”
• Once you’re happy with your customized tone, save it so that you can recall it later.
