Dynamic DSP

We’ve offered up a whole lot of sound possibilities in POD HD Pro 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. 

Currently selected Model 
is automatically bypassed, 
with DSP message shown

DSP Limit alert is 
temporarily displayed

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.
