Hi,

is their any message that is sent from max to the externals when the dsp is turned off? In other words I am looking for the equivalent of addmess(myexternal_dsp,"dsp", A_CANT, 0); to call a function when the user turn the dsp off.
Does it exist?

Cheers,

Charly

I have the same question for Max 8. Is there a method that get's called when DSP is off so that I can hook some cleanup functions to it?

I know there's the dsp_state~ object, but is there anything at the Max c-api level that does the same?

In your main function add a 'dspstate' method, then add a function that handles the call and does whatever you want to happen.
hth

class_addmethod(c, (method)myObj_dspstate, "dspstate", A_CANT, 0);
...

void myObj_dspstate(t_myObj *x, long n) 
{
    if(n) ...
    else ...
}
