And if anyone with a Yamaha network receiver wants to try PEQedit, the basic instructions are:
Turn your receiver on and run the program (filters can be read but not changed unless powered on). Then:
Enter the IP address of the receiver.
Press the red Open button and it should turn green if it can communicate.
It should also display the specific model number and series.
From the menu bar select View / Response Curve.
Select a specific PEQ Type and Speaker Pattern, then press UPLOAD to PC.
The slider controls and the response curve should be showing the settings read from the receiver.
Choose any Channel to display filters for that channel.
You can only make changes to Manual mode.
With manual selected you can change the filters, then press DOWNLOAD to AVR.
(downloading is pretty slow to send all 7 filters for all channels, so I really need to make it possible to download only one filter).
The response curve shows the individual filters in red and the combined response in black.
When you make changes nothing is currently changed in the AVR in real time, only the DOWNLOAD button makes changes.
It would definitely be useful to have a mode where the changes have an immediate effect.
Right now it's just a program in development, but any feedback would be useful if people have ideas what else it should do.
Note that even if you don't have one of these receivers, you can still play with the filter parameters to get a feel for how Q and the other parameters affect the filter shape.
