If like me you have a very small memory, and you like dumb-proof procedure, here is one I've done for adding Max5 support back to the current SDK's simplemsp~ code.

Here it is in compressed HTML (because the forum refuses html itself)

notes on adapting the Max SDK.md.html.zip

I'll post the content in the next comment.

Hello
If like me you have a very small memory, and you like dumb-proof procedure, here is one I've done for adding Max5 support back to the 

dumb-proof-procedure-to-adapt-the-current-sdk-to-support-max5

The copy/paste loses code colouring but hey, in case you don't want to download 6.53kB...

copy the simpledsp~ folder, keeping it in the same folder (source/audio/)

change the name of the project file and its .c

drag the renamed .c in there, accepting the default options

click on 'max-external' at the top of the window, and then manage schemes

delete the current theme with minus bottom left

click the top right button (autocreate schemes now)

open the .c file, and do a search and replace all, replacing 'simplemsp' by the new name of your external

compile - you should get an external bearing your new name, doing the basic simpledsp~ code (signal in is added to float in)

add the dsp message prototype (for the 32bit audio path support) and its dsp perform routine


in the method prototype section declare (replacing YOURNAME by your object name):void YOURNAME_dsp(t_YOURNAME *x, t_signal **sp);t_int *YOURNAME_perform(t_int *w);

// registers a function for the 64 bit signal chain in Maxvoid YOURNAME_dsp(t_YOURNAME *x, t_signal **sp){ dsp_add(YOURNAME_perform, 4, x, sp[0]->s_vec, sp[1]->s_vec, sp[0]->s_n); post("dsp32");}
// perform 32bitt_int *YOURNAME_perform(t_int *w){ // transfer values from the object to local variables    t_YOURNAME *x = (t_YOURNAME *)(w[1]); // object pointer float *entree = (float *)(w[2]); // input pointer float *sortie = (float *)(w[3]); // output pointer int n = (int)(w[4]);  while (n--) *sortie++ = *entree++ + x->offset;  // you have to return the NEXT pointer in the array OR MAX WILL CRASH return w + 5;}

you need to change the declaration of the main function from
void ext_main(void *r)
to
int C74_EXPORT main()

then you need to add the 'dsp' message declaration in the main function, just under the 'dsp64' one, like so:class_addmethod(c, (method)YOURNAME_dsp, "dsp",    A_CANT, 0);
