final case class Stepper(rate: MaybeRate, trig: GE, reset: GE = 0, lo: GE = 0, hi: GE = 2147483583, step: GE = 1, resetVal: GE = 0) extends SingleOut with Product with Serializable

A pulse counting UGen. Each trigger increments a counter which is output as a signal. The counter wraps inside the interval from lo to hi (inclusive). That if you use a lo other than zero, you might want to adjust resetVal as well. Stepper always starts with the value in resetVal , no matter what lo is or whether the reset trigger is high or not.

trig

The trigger signal which increments the counter. A trigger happens when the signal changes from non-positive to positive. Note that if the UGen is created with the trigger initially high, the counter will also be incremented immediately. Thus a Stepper.kr(Impulse.kr(1)) will begin by outputting 1 . If you want to avoid this, you could their subtract Impulse.kr(0) from the trigger input, or set resetVal to hi . E.g. Stepper.kr(Impulse.kr(1), lo = 0, hi = 4, resetVal = 4) will produce the sequence 0, 1, 2, 4, 0, ...

reset

A trigger which resets the counter to resetVal immediately.

lo

The minimum value output. For a decremental step value, the counter jumps to hi if it were to fall below lo .

hi

The maximum value output. For an incremental step value, the counter jumps to lo if it were to rise beyond hi . Note that values greater than 0x7FFFFFBF (the default) cause numeric overflow and the UGen to malfunction.

step

The amount by which the counter increases or decreases upon receiving triggers. Note that if you use a decremental counter, still lo must be the minimum and hi must be the maximum value output. If lo > hi , the UGen behaves wrongly. In the case of decremental counter, set resetVal to hi . E.g. to count from 4 down to 0, use Stepper.kr(trig, lo = 0, hi = 4, step = -1, resetVal = 4) , or, if you want to ignore an initial high trigger, you could do Stepper.kr(Impulse.kr(1), lo = 0, hi = 4, step = -1, resetVal = 0) -- so resetVal is lo but due to the initial trigger from Impulse the Stepper will in fact start outputting from 4 .
