Definitely to augment. Consider the following:
Take two Pam's outputs. Run one to one side of an AND gate, and the other to the other side. Then take your modified timing signal out of the AND gate's output. What will happen as a result is that the gate will only send a gate signal when there is a 'high' state (ie: gate on) present at both inputs. So unless the Pam's outputs a gate at the same time on both channels, no gate gets sent to whereever it's patched. By doing lots of these little tricks, plus adding things like gate delays, skippers, swingers, dividers, multipliers and so on to screw around with the 'raw' gate signals, you open up a big box of polyrhythmic craziness that wouldn't normally be doable without those + some logic. Or...let's say you have a pattern running on Pam's, but it should only pass when stage #6 is active on the DFAM. Set the DFAM's 'velocity' row to only output voltage on #6 (the rest of the row has the pots all the way down), patch 'velocity' to one side of an AND gate, and the Pam's pattern to the other side. So...when the 'velocity' CV is present plus the pattern at the AND inputs, the pattern gets through the gate...but only while step #6 is active. So, yeah...lots of fun like that, which can really open up loads of interaction between sequencers, rhythmic elements, etc. Use your imagination; I'm sure you can come up with loads more ideas!
