Sure, the patch is trivial, and it is here:

#N canvas 0 393 1255 314 10;
#X obj 249 139 osc~;
#X obj 276 280 dac~;
#X floatatom 199 73 50 0 0 0 - - -;
#X obj 187 20 hsl 128 15 0 19000 0 0 empty empty empty -2 -8 0 10 -262144
-1 -1 1100 1;
#X connect 0 0 1 0;
#X connect 0 0 1 1;
#X connect 2 0 0 0;
#X connect 3 0 2 0;


That's all there is to it.
