delta or diff object?

January 12, 2012 | 10:05 pm

Sort of new to the world of max.

Is there an object that will output the difference between the incoming value on this bang and the last bang?

ie: value@lastbang – value@thisbang

I know I can make it with a couple of objects, just wondering if there is a single object that does it?

Other objects related to derivatives as such?

velocity, acceleration, etc.

there should be, but I don’t think there is. if you go to and search for ‘delta’ there’s plenty to choose from…

Here’s a super-simple (but totally usable) one for ints.

Very cool.
What does # indicate?
