Re: [PD] PLEASE HELP ME (CLICKS AND POPS FROM KNOBS)
The frequency inlets of [lop~] and [hip~] don't take signals, that's why you get clicks. You have to implement the filters yourself using [rpole~], [rzero~], [cpole~] and [czero~]. You can read the theory here http://msp.ucsd.edu/techniques/latest/book-html/node139.html Or you can go to Pd's forum and check some post from Maelstorm (administrator). His posting signature is his library of abstractions that include all kinds of filters driven by signals too.

Re: [PD] prevent opening of patches
That's useful, but up until recently you had to create a second instance of Pd from the command line anyway, since OSX would show you the instance you already had if you tried to open it from the operating system. Or...have I missed the point? My friend and collaborator always needs two Pd's, one for Gemnotes and one for audio processing, to play my musioc...and we wrote a BASH script to launch the gemnotes one after the audio one was set up. well, personally most times, when developing, I need to create abstractions and use global variables just to experiment with stuff. And if two instances of Pd are opened when you don't want it, it can be very annoying. Even worst scenario when you are teaching, student might open 4 patches at a time, and as 4 Pd instances are launched, and it's a mess. I always wondered whether we could have a flag in Pd GUI that set this kind of configuration.

[PD] Gridflow and fonts on Raspberry Pi

I guess Gridflow could be the right library to use if it can manage fonts and if it is stable on RPi ? Is there an other library (or idea) for this purpose ? For example : a pd window in fullscreen with a canvas with text ? In this case, how to achieve that (fullscreen without menubar and window title bar with pd).

[PD] alsa and jack on ARM/Wandbaord
I've got a Wandboard* here for some testing and I can't get Alsa to work in duplex. Testing with arecord produces a soundfile and aplay plays it back. But starting Pd with Alsa or jack gives the dreaded errors about the resource being in use. Pd's performance with just playback is pretty good - pvoc example takes 20% cpu at 10ms latency - but I want to process some audio input! I built my own armhf kernel (much faster than armel) and have a very basic Ubuntu filesystem in place. There's no obvious process like pulseaudio grabbing the audio hardware either. Jack has all of the limits.conf set high. The audio device is sgtl5000 from Freescale. What's the usual setup and troubleshooting process for Pd on Linux these days? Seems like these things are mostly sorted on x86, so maybe the problem is driver or armhf related.

Re: [PD] alsa and jack on ARM/Wandbaord
Hello Chris, It may be unrelated but with Debian Squeeze on particular Intel laptops (Panasonic CF-74 and CF-19) I've always experienced that same problem: recording works, playback works, but no duplex sound from Pd or Jack out of the box. In these cases it was a matter of unchecking as many unused options as possible in the ALSA mixer, in particular 'IEC958 Default PCM' (don't know if you have that option). That used to make the difference every time though I still don't know why.

Re: [PD] alsa and jack on ARM/Wandbaord
Hi Katja This is a pretty basic device with just hw0:0 for capture and playback, but I will double check the mixer settings. Someone from Freescale has been in touch and it looks like either a driver issue (fixable) or errata on the board (not fixable). I might try a USB audio device. Anyone know what ones work with ARM?
