If you look closely you will see that this one counts from 0-9 on the
first round, then from 1-9 on the next rounds. Generally I prefer to
count from 0 to maxstep-1, a "modulo counter" that is easily build
with 

    [r $0-restart]
    |
    [f 0]/[+ 1]/[mod 8]
    |           |
    |           [s $0-restart]
    |
    counter output here

Attached is a little counting tutorial I once did.

Ciao

#X text 65 75 Counting in Pd doesn't require externals \, you can also
count with the builtin objects. The basic idiom to remember is [f 0]
x [+ 1]:;
#X text 280 755 <= count from 0 to 3 (where 3 == 4 - 1);
#X text 87 376 To start over \, send the new starting value to the
right outlet of the float:;
#X text 193 459 <= RESET using right inlet of float;
#X text 92 634 If you want to count from 0 to a max-value and then
start over \, use a "Modulo N" counter. Note \, that the [mod] is inserted
*between* the [+ 1] and the float. To count until N use a [mod N-1]

#X text 62 78 With a little change to the counter idiom you get another
operation: an accumulator to sum incoming numbers.;
#X text 63 125 Remember the counter:;
#X obj 94 156 f 0;
#X obj 138 214 f 0;
#X obj 141 157 +;
#X obj 90 214 +;
#X obj 134 301 f 0;
#X obj 86 301 +;
#X text 63 238 and send numbers into it:;
#X floatatom 86 331 5 0 0 0 - - -;
#X obj 86 359 print;
#X obj 129 480 f 0;
#X obj 81 480 +;

#X msg 86 272 1 \, 2 \, 3 \, 4 \, 5;
#X msg 97 451 0;
#X text 57 401 Resetting works like this:;
#X text 81 581 And if you only want the final result \, you can store
the intermediate sums in a float object:;
#X obj 152 703 f 0;
#X obj 104 703 +;
#X msg 104 652 1 \, 2 \, 3 \, 4 \, 5;
#X floatatom 74 749 5 0 0 0 - - -;

#X msg 31 601 bang;
#X text 146 333 == 1+2+3+4+5 = 15;
#X text 60 189 Now just turn the objects around like this:;
#X text 166 452 <== Reset;
#X obj 374 483 f 0;
#X obj 326 483 +;
#X msg 326 432 1 \, 2 \, 3 \, 4 \, 5;
