Doing things like this is nice with my k_cext external:

The following patch does what you want:


#N canvas 56 333 589 504 10;
#X obj 73 309 nbx 5 14 -1e+37 1e+37 0 0 empty empty empty 0 -6 0 10
-262144 -1 -1 10 256;
#X obj 297 311 nbx 5 14 -1e+37 1e+37 0 0 empty empty empty 0 -6 0 10
-262144 -1 -1 1000 256;
#X msg 59 36 bang;
#X obj 60 115 k_cext 7 2 0 0 10 1 100 1000 100 \; int i \, j \; for(i=I(1)
SC i<=I(2) SC i+=I(3)) BEGIN \; . for(j=I(4) SC j<=I(5) SC j+=I(6))
BEGIN \; . . O0(i) \; . . O1(j) \; . END \; END \;;
#X connect 2 0 3 0;
#X connect 3 0 0 0;
#X connect 3 1 1 0;
