For netpd I wanted a master clock and a way to create different timings that stay in sync with the master also while changing tempo. One issue was to be able to change tempo mid-period. [rh_metro] does that. Another issue was to have a 4/4 master clock and derive any arbitrary integer division timing of it (for instance: 13/8 means 'create 13 ticks within the period of 8 regular ticks'). [master-poly] takes the main clock from the master.pd patch and takes the poly timing as arguments or as message. Unfortunately, the code is not optimally modularized to be of general use outside of the netpd context, though the technical problems are tackled. But then, shortly after I was working on that, a new Pd version with the timing classes support many new methods was released. So, with newer Pds those kind of timing problems can be solved much more elegantly and with much less code. If you're still interested in having a look at the netpd stuff, check: * abs/rh_metropd * patches/master.pd * abs/master-poly.pd from https://github.com/reduzent/netpd2-patches Roman
