I've downloaded version 1.2.0 rev.1 of winPCD and really like this tool. I was able to import an existing .csp file created from PCD 7 and FRD and ZMA files as well, and was off and running.
Off the bat, I could take advantage of some really key improvements over PCD. In particular, I like the schematic overlay window where you can see exactly how the components are laid out and adjust their values on the fly. Very cool how the separate system graph is updated in real time; in PCD I never could adjust the values and see the effect in the system graph at the same time.
I also like the way the session file saves all the crossover values and also remembers all the FRD and ZMA files that should be loaded. But here is where I have run into a problem, which might be user error. After saving and then reloading a session file for a 3-way, it looks like the mid and woofer response is not being calculated with their respective filters and summed.
I get a dialog like the following 6 times:
But here is the system response, which does not appear correct:
When I tab into the individual driver screens, the tweeter looks normal, but the mid and the woofer do not. Here is what the mid looks like, where filtered SPL appears to be missing:
Any clue what might be going on?
