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)

The functions in the Max SDK have an odd behaviour : canvas_start_dsp() works fine, but canvas_stop_dsp() is buggy.

It's actually the same problem as the one brought up in this thread :

- which is why I'm trying to find a way to get around this problem, maybe by sending directly to Max a ";dsp stop" message from my external

Anybody has an idea ?

object_method(gensym("dsp")->s_thing, gensym("stop"));


FYI, to do the same thing as ;dsp stop from C code, you can do this:
