Re: [PD] [PD-announce] new GUI obect: filterview, for generating and seeing biquad coefficients
Hans,
This is so exciting. The binary is working here on a MacIntosh 2.8 GHz Intel Core 2 Duo with OS 10.6.8. I thought you might appreciate some quick user feedback.
When I click the graphic, it lets me adjust frequency and amplitude, but then my cursor gets stuck to it like mouse up isn't working. Every time I click it adds another red vertical line.
A slight bit more documentation would be helpful in the help patch, too, explaining how one can interact with the graph with the mouse. Is it possible to change the bandwidth with the GUI? is there a key combination one can hold?

Ok, big update, this should work a lot better.
http://puredata.info/downloads/filterview
I changed the formula below to be a fixed resolution of 5 pixels. I was thinking that this should be generalized into a general biquad~ library, so with objects like [bandpass] to calculate biquad coefficients. The calculations could all be written in C as a shared library, then the Tcl code could use those C functions also, which I think would allow for 1 pixel resolution. My guess is that doing the math in C would make things noticeably faster.

Hmm, I thought I got rid of that issue with it sticking to the mouse pointer... arg. Can you tell me the steps to reproduce it?
I should add more to the help patch. The goal was to make it as self-explanatory as possible. So you can click and move the filter center and gain, and click and drag on the vertical bandwidth lines to control the bandwidth.

Here are the steps I took:
I opened the help patch in the directory with the .pd_darwin binary file.
I turned on audio.
I selected a high pass filter.
I wondered if changing the bandwidth would do anything, so I moved my cursor over one of the red lines that show bandwidth. The line became highlighted but I could not move it from its position.
I selected a band pass filter.
I attempted to move the bandwidth, again, to no avail.
I single-clicked (no hold) in the area between the bandwidth markers and began changing the frequency of the band pass filter.
The filter continued following my pointer as long as it was inside the borders of the GUI.
If I moved my pointer out of the GUI and pressed command-E, the frequency would stop moving.
Pressing command-E, again, would resume following my pointer without my clicking anywhere.
Then, Pd failed with a spinning beach ball. A force quit was necessary.
In the meantime, when I clicked on the patch's titlebar, it showed one of the cursor symbols for changing the bandwidth.
Let me know if I can help test it more.
I suppose I left out one bit of information. I am running Pd-extended 0.42.5-extended.

The last bit is the key bit of information: filterview will only work on 0.43, not 0.42.5. It relies on some of the new features of 0.43.

With filterview version 0.1 I had similar issues as described by Samuel, on OSX 10.5 and with Pd 0.43, but with filterview version 0.2 the 'stick to the cursor after mouseup problem' seems to be solved for mentioned configuration.
Thanks for this wonderful object, Hans and Mike!
