Re: [sc-users] python->OSC->scsynth

it is more the scosc module by patrick that does the job, the ixi sc library just wraps that. He uses a different way to setup the socket connection than the SimpleOSC library. I am not sure that patrick is maintaining or developing it further. The last time i checked it (last year or so) it took me some time even to find the SVN repository because the he moved to a new URL but there was no webpage about this. Maybe he is just too busy to make it public.

Definitely, there's something in the structure client server or in OSC messages which I can not understand. I tried all ways, including sending messages to sclang via OSCresponder. Fortunately, as I have suggested altern, using the ixi's library sc all goes well, provided that the connections are properly carried out jack (on linux) and Synthdefs are added to a folder synthdefs in the working directory. 

Thank you.

        altern2 was right, thanks,  there were problems with the jackd
        start and connections.

        With this code I have fixed:
         [code]
         import osc

        import subprocess

        import time

        import os, sys

        import random

        path = os.path.dirname(sys.argv[0])

        pathname = os.path.abspath(path)

        subprocess.Popen("sudo jackd -R -dalsa -dhw:0 -r44100 -p256 -S",
        shell=True)

        time.sleep(2)

        subprocess.Popen("sudo scsynth -u 57110", shell=True)

        time.sleep(5)

        subprocess.Popen("sudo jack_connect SuperCollider:out_1
        system:playback_1", shell=True)

        subprocess.Popen("sudo jack_connect SuperCollider:out_2
        system:playback_2", shell=True)

        time.sleep(2)

        osc.init()

        osc.sendMsg("/d_load", ["sinecdote.scsyndef"], "127.0.0.1", 57110)

        osc.sendMsg("/s_new", ["sinecdote", "1000"], "127.0.0.1", 57110)

        time.sleep(1)

        for i in range(10):

        time.sleep(1)

        rate = random.uniform(100.0, 400.0)

        print i,":",rate

        osc.sendMsg("/n_set", ["1000", "freq", "%s" %(rate)],
        "127.0.0.1", 57110)

        time.sleep(5)

        osc.sendMsg("/quit", [], "127.0.0.1", 57110)

        subprocess.Popen("sudo killall jackd", shell=True)

        [\end code]

         but I get the following message:
         FAILURE /s_new duplicate node ID
         i tried to refer synthdef in the supercollider directory and in
        the code directory but no as effect.


    did you get this to work? i remember that i had problems with the
    range of numbers i asigned to the nodes. I just checked one of my
    examples and i used a number 1967 for the synthdef nodes, but then i
    used 1000 for sample b_allocRead. I paste my example below, there
    was a thread about this on the list, a couple of years ago maybe? I
    am using sc, scsynth and scosc modules.


    import sc, time, os

    sc.start(verbose=1)

    time.sleep(3) # wait while sound plays

    s = sc.sc.server ###################

    s.sendMsg('/d_load',
    os.path.join(os.getcwd(),'synthdefs','StereoPlayer.scsyndef'));

    time.sleep(1)

    # no data at buffer index 500 -- silent synth
    s.sendMsg("/s_new", "StereoPlayer", 1967)

    time.sleep(1)

    s.sendMsg('/b_allocRead', 1000,
    os.path.join(os.getcwd(),'sounds','numeros.wav'), 0, -1);

    time.sleep(1)

    # but here, of course
    s.sendMsg("/n_set", 1967, "bufnum", 1000);
    s.sendMsg("/n_set", 1967, "pos", 0.1);


    s.sendMsg('/d_load',
    os.path.join(os.getcwd(),'synthdefs','sine.scsyndef'));

    time.sleep(1)

    s.sendMsg("/s_new", "sine", 1968);

    time.sleep(3)

    s.sendMsg("/quit")
