Version 1.1 is ready to release. The changes are largely related to the user interface based on feedback. The system SPL and impedance graphs are now on one of several optional windows as are the instructions, the schematic layouts and the generic circuits. These can all be re-sized to the users desire.
One very useful addition is the creation of a new set of schematics, also in an optional window. These are patterned after the schematic layouts with the addition of overlays of the circuit component values. Rather than having to match design controls on the driver tab pages to the schematic, these component values are updated on a real-time basis. Only those components that are active in the design appear on them and only the circuits that are active in the design appear in the window. This should be especially helpful to new users. They can also be printed and will include the component values. The only limitation is that circuits will not re-size when the window is re-sized. This is due to the difficulty of the component control placement and changes with a re-size.

The first version of Windows Passive Crossover Designer has been released. I had hoped to get more testing and feedback, but more users should solve that issue. While waiting for feedback I continued to test and modify. Full details of this progress can be found at my main web site which is also where the program is available for download. Use the link labeled “WinPCD progress details” in the right column.
Please take the poll posted here. I’m curious to learn more about users’ habits. The poll is based on the crossover categories originally in Jeff Bagby’s PCD spreadsheet that is now (partially) implemented in WinPCD. It’s not quite the poll I could use best, that would be listing by most-to-least often, but this will still help to give me an idea of what you use the most often.
You cannot comment unless you are a “subscriber”. Spamming seems to be too much of an issue with open comments in WordPress, but I would appreciate user feedback here, so please send an email if you would like to comment. I will create a subscriber account for you.
If you have PCD 7.0 by Jeff, you can import the session files exported by the PCD. You will need to manually change a couple of settings in the driver screens because there are slight differences for things like crossover type, parallel circuits, etc., but all crossover data should import unchanged. You can also export from WinPCD and I think it will import in PCD, but I never got around to testing that.
The code for the midrange has been added, so 3-way design now works. It hasn’t been tested as thoroughly as the 2-way section, but it was largely duplication/re-use of the 2-way code. This completes the core of the code, the basis of the application. In fact, I was surprised when I was able to complete this part in less than three days work with maybe a half day devoted to finding a bug that was the result of an editing error. It’s in the hands of a few beta testers now. I may try to corral a few more.
The remaining passive sections will take longer, since they are not directly extensions of the current code, but will be created in the same manner. The extent of new code will be more than the midrange of the 3-way, but will be more a function of time, not difficulty.
The box section yet to be done is a different matter. That will largely be all new and since I’ve not coded any box calculations, I don’t yet know how much time that will require.
The development of the first beta is essentially complete. It provides full design capability for 2-way systems. The only parts not complete are the power response, exporting summed curves to files and system impedance compensation. None of these are essential to be able to design. It is being tested now. I still have to decide if I’ll make it available for download before starting work on the 3-way section.
This blog is for the new Windows Passive Crossover Designer (WinPCD). The host, Yahoo, provides built in WordPress blog capability. This provides a feedback mechanism. Certainly better than making updates to my HTML pages.
I’m not sure yet how to handle feedback. I’ve got to check out WordPress functions to prevent spamming. in the end this may be a good thing, since only those who are serious about using WinPCD will be more involved to the point of registering to comment.
