How do I limit a counter between two numbers (in this case 0 and 127) so that it does not start over again?

Im trying to convert a rotary encoders inc/dec mesaage (0 and 127) into an absolute value (between 0 and 127 depending upon the encoders position).

Using counter I can set min and max values of 0 and 127, but I need the counter to stop when it reaches these. For example when I turn the encoder from 0 around to 127 and further, I need the counter to stop counting at 127 and stay at that value untill I turn the encoder down, when the counter will need to start counting down too. At the moment when the counter reaches 127 it will start counting again from 0.

My reason for doing this is because of a quirk of Ableton live 6's midi output. I am trying to light LEDs with the output from Live, but for some reason when an encoder is mapped to a control it will only output a midi message on the increment and not the decrement. This function works fine for absolute values that potentionmeters and buttons use. So if I can make an encoder apear as a potentiometer within live it will hopefully work.

You could use [moses] to limit numbers, something like the attached.

Thanks for the suggestion Maelstorm.

I found another solution using [limit] and [float] that works (see attached example).

the [select] will need more numbers in it, as the quicker the encoder is turned the output changes from 1 or 127 to the next in the sequence, so with the example file there is a limit to the speed the encoder can be turned. The other thing I found with it is that the encoder needed turning 1.5 to 2 times compared to a pot which is about 3/4 of a turn. Easily solved by limiting the slider in properties by 1/4 and mulitiplying the output the output by 4.

I'm not entirely sure what's going on in your patch. Are you expected the math operators to output a list? Because it's only sending out one value, which is coming out of the first outlet of [unpack]. The rest aren't really doing anything. Also, with 1-10 the values only increase (and vice versa with the others). Wouldn't this be a problem when turning the encoder down?

filter with moses 64, go into a counter with a [clip 0 127] intercepted, well look at attached.

Thanks Pulsed.

Your solution is much neater and smaller than mine.

I have been using mine with no problems at all for quite a while now. I think ill go back and make a new patch using moses as it will reduce the overall size of my patch quite alot, as it turned out quite big in the end.

your welcome
