Hello all,

(Further adventures with [pd~]): I have my ‘polywavesynth’ synthesizer working 
with [pd~]; well, except that…no sound comes out!

- The message ‘unknown audio API specified’ is displayed in the subprocess pd 
window.
- I have the two audio outputs of the subprocess wired to a 2 channel [dac~], 
and there are no audio inputs to the subprocess.
- The parent process is using PortAudio, and the subprocess appears to 
(correctly?) have no audio API selected.
- The subprocess Audio Settings show that the input device is unchecked and is 
called ‘input device 1’;
- The corresponding output device is checked and says ‘(same as input device)’.

Am I doing something wrong?


Thanks,

Hi Cyrille (and Iohannes),

This is embarrassing; I consulted the [pd~] help file many times, but I somehow 
didn’t find the right placement for the -nogui flag and kept getting errors – I 
thought I was missing something basic. With your kind encouragement, I have 
found the right syntax:

[pd~ start -nogui foo.pd(

Hope this can help someone else as dumb as me.


Phil

The answer is in pd~ help file!


"pd~ start" takes as arguments
any startup flags you wish to send the sub-process. For example, specify 
"-nogui" to
stop the sub-process's GUI from appearing.
