You can still use a counter, just send a bunch of bangs at once.
Or, a more complex thing...
Use line. Make sure that the resolution is enough to hit each int. Run the output of the line into an int box (to truncate it). Send the output of the int box into change. A bit more complex, but should do it.
However, it would be trivial to write this object. I'll try to do it tonight. It will have a start point, an end point, and an increment. Every time you send it a bang, it will send out a whole slew of numbers.
Is there an object like this in Opcode Max? If so, I'll use the same name.
