    My first try with Karplus-Strong synthesis on Pure Data. Two identical synthesizers, with 8 variable parameters each, controlled with a MIDI device. It sounds like there is some kind of reverb, but there is none.

    Hi,
    I have the following issue : Midi stops working when Midi messages are received by PD at a high rate (for instance, if i move several sliders or knobs very fast). Pd doesn't crash, but objects like [ctlin] stop working, and start working again if go to my MIDI settings and select my device again. It happens with various Midi devices.
    Any ideas?
    PD 0.48-1 on osx, MIDI via usb.

    I'm having issues with the audio settings. First thing I noticed a while ago is that I couldn't save my settings. I don't remember when it started, maybe when 0.47 was released. It's a bit tedious as I have to set my sound card every time I launch PD, but I got used to it. Then a few days ago I noticed PD crashes when I try to change the block size (only 64 and 128 work). And today, as I receive MIDI data from a Bela board over usb, I noticed that I sometimes don't receive the MIDI messages (I know they are correctly sent), and things get back to normal when I open my MIDI settings. I don't know if these issues are related... and I'm also wondering if it might be related to this issue I posted yesterday :
    https://forum.pdpatchrepo.info/topic/11282/pd-crashes-with-osc

    I'm having an increasing number of problems of this kind, could it be related to my aging mac (osx 10.7.5) ?

    I know for sure my patch is not at fault : it happens with a single stream of osc messages, with a patch containing only one abject, either [netreceive] or [udpreceive]. Anyway, for now i guess i'm going to use MIDI...

    Thanks for your answer David. Yes I've used this soundcard for years with PD, it works very well. Actually, in an attempt to solve this problem I tried to change the block size from the audio settings, and I realized pd crashes when I do so, only 64 and 128 work. [block~] works normally. I've been told on the bela forum that the problem might be the high frequency of the osc messages (bela's default block size is 16, i.e. about 3000 osc messages per second). The only thing that works for now is to set bela's block size to its maximum, 128. I've also noticed that the cpu load remains very low, even when PD starts to go wrong...

    Hi,
    I'm trying to run a PD patch that reads sensor values from a Bela board through OSC, and I have this strange thing happening.
    If I run my patch with the default audio settings (built-in sound card), everything works fine. But if I switch to my usb sound card (RME fireface uc) PD's GUI totally crashes, and OSC goes wrong, data transmission is delayed, even when DSP is off. PD gets back to normal when I stop the program on Bela. I know the patch itself is not at fault, as it still happens with only one object (both [udpreceive] and [netreceive]. Any ideas? I run PD 0.48-1 on OSX 10.7.5.

    Hi, here is a piece for two alto saxophones and live electronics I completed a month ago. The whole electronic process is done with Pure Data. Mostly granular playback and transposition.

    Hi, I'm fairly new to arduino. I'm working on a PD patch that gets data out of an accelerometer (a MMA8451). It works fine, but I'd like to know something in order to improve things. The arduino code is very simple, it outputs data this way :

    So I get a stream of ascii values in Pure Data. I use 'a', 'b' and 'c' as arbitrary values in order to separate the x, y and z values in my patch. Just to convert my data into numeric values, I had to do this ugly piece of patch :
    fora2.jpg
    There might be a more elegant way to do it, but my question is the following : is there a way to get numeric values directly out of arduino, so I get them directly with comport? A kind of list I would just have to unpack?

    Hi. You need to use just one instance of each [receive] object, and then use [trigger f f].
    I strongly suggest you look into the [trigger] object. Correctly managing the order of operations is essential in Pure Data.
