Crashes are usually because memory hasn't been allocated properly. I'd check x->current and x->step. Hooking up to gdb will give you a lot more info. Search puredata.info for 'gdb' for a little howto.

Hi all,

The following code crashes Pd when the randomwalk object receives a bang... I'm stuck as to why, can anyone see a reason? void randomwalk_bang(t_randomwalk *x) { t_float randval = rand() % 2; if(randval == 0) randval = -1; if(randval == 1) randval = 1; x->current += (x->step * randval); outlet_float(x->f_out, x->current); }

Thanks in advance,

-Greg

check that x->f_out is really set to a return value of outlet_new.
