How to lower controller data resolution?

    Hey I'm looking for a way lower the resolution of the output data of a midi controller that i'm sending out of Max(such as bendout). I've been using the slide object to smooth the in/output of controllers but now i'm looking for a way do exactly the opposite, so that data will be output in jumps of 5,10 or as many values as i decide (and still keep the ranga of 0-127).
    Thanx! David

      Have a play with multiplying, adding or dividing the data based on the input value before it's sent out. Then use an operator such as [if] to stop data passing out if it exceeds 127. Be careful not to get float outputs otherwise MIDI won't recognise them.

      A simple way would be to use two consecutive [scale] objects. In the attached example 14bit Pitchbens (0-16383) is being forced to a range of 0 -15 (16 steps) and then scaled to a range 0 -127. You'd obviously need to massage the settings to get what is right for your specific use(s)...

      thanx for the tips. the patch is simple and yet very efficient. the only thing i modified is the second scale object, instead i used a zmap so that data from my different controllers wont exceed 0-127.
