hi Thomas,

I'm still not completely sure whether insertion of new signal objects into a patcher is guaranteed to be click-free. Therefore a basic question:

btw, updating dsp chain might matter not only directly due to some node being inserted or deleted, but also when the output depends on execution order (remote connections, feedback loops), which is usually undefined (but in many cases one may expect it to remain unchanged).

Is there a global signal graph in PD or are there many local ones (e.g. one per patcher) and what (e.g. which objects) are the nodes where these interconnect?

the graphs are built for 'root' patchers, which do not interconnect (other then remotely), and anyway they are all sorted into a single dsp chain. This chain is recreated for any editing operation which might involve dsp objects or signal connections (also resizing of an array if ``used in dsp'').

Thomas, are you going to make a polyphonic instrument with real dynamic voice (aka instance) allocation ala Csound, a super-poly~ we all dream of?
