I'm trying to make my MSP external stop the DSP (and after some stuff start it again).
I know of the canvas_stop_dsp() and canvas_start_dsp() functions, but the behaviour for canvas_stop_dsp is odd : it just doesn't work.
I tried calling canvas_stop_dsp() inside a very simple patcher, with my external, and a ezadc~ connected to a ezdac~. The color of the ezdac/ezdca changes back to inactive, but the sound is still there, proof that the DSP hasn't really stopped
While this method doesn't work, I tried sending a message directly to the Max application (using a message box with "; dsp stop"), and this works appropriately.
Does anyone know if it's possible to send a message directly to the Max app from inside an external ? (a bit like with object_method(void *x, t_symbol *s), but with the Max app instead of an object)
Thanks for the help !
