thanks for your answer. 

as a first project i wanted to explore the possibilites in treating the output of a hexaphonic bass pickup with puredata. a pll oscillator with the bass string as input (filtered to remove unwanted harmonics) sprang to mind.


other topics i am currently investigating:

-pitch to voltage from the different strings at low latency (difficult with bass frequencies, i took a gr300 guitar synth approach) 
-proper attack detection
-adaptive filtering of the individual strings overtones to remove octave jumps from the pitch to voltage block

Synchronizing oscillators is a good topic and there should be some better options with digital alone than with simulations of the analog circuits.

Synchronization in natural systems involves a phase-resetting oscillator.  The key behavior is the oscillator responds to input events, by adjusting its phase by an amount that depends on the current state of the oscillator.  This is enough to produce synchronization within a small range of nearby frequencies, by itself, but adjusting frequency is also possible.

What did you have in mind?  Any specific behavior it needs to have?

hi list,

does somebody have a patched version of a PLL (phase locked loop) in PD? or building blocks of it...

cheers
