Hi Nik,

Maybe the problem comes from your Jack version. Jack 2 is steadier with Chuck. I often had your error when using Jack 1.
But before changing your Jack installation, you can try with alsa.

Have fun,
Julien

Hello nik,

Your example works ok for me on OSX, with a buzz_send.ck <http://buzz_send.ck> class that sends OSC messages with some random values every 0.1 seconds.

It makes an awful racket though, I think you might be exceeding the bounds of your DAC with some values.

    Hi everybody,

    i have some osc-triggered synth shreds like the one attached, and
    tried to spice things up using pan control (basic, i know ...).

    Now, for the music i have in my mind, the respective shred is
    triggered about 10 - 15 times per second via OSC, and there are
    multiple of those
    shreds, including some granulation shreds.

    Now, even when i only trigger the attached shred with different
    pan values, ChucK crashes after a few seconds ... so i don't know,
    is the
    shred faulty, or is chuck simply not capable for what i have in mind ?

    Btw, i'm using Arch linux on a pretty recent laptop with plenty of
    ram and a fast processor, so resources should not be an issue ...

    ChucK error message:
    (JACK) the JACK server is shutting down this client...
    ... stream stopped and closed!
    [chuck]: cleaning up...
    terminate called after throwing an instance of 'RtError'
      what():  RtApi:: a stream is not open!


    JACK error message
    subgraph starting at ChucK timed out (subgraph_wait_fd=9, status =
    0, state = Running, pollret = 0 revents = 0x0)

    Regards,
    nik
