ofxPDSP snapshots of audio signals at control rate


I am working for the first time with ofxPDSP and I am quite inexperienced with DSP programming in C++. I need to realize a project with a bunch of synced LFO’s, generating signals to control LED’s over Artet. I would like to keep the signal flow at Audiorate until the moment I put the values out to DMX. I am very new to the patching system in PDSP and I wonder if there is a possibility to get Snapshots from audio signals at control rate (OF framerate)?

As I normally do DSP stuff with Max/Msp I dont really know if I am going in the right direction with this. For performance reasons I had to switch from Max to OF, and I am not really sure if my approach is the best way to do this. If you think there is a better solution please let me know, I would appreciate it.
