phasor~ ramp control

    Sep 04 2011 | 5:53 pm
    Hi all,
    I'm trying to do math on a phasor~ object, so that I have the regular output going from 0 to 1 reading through a buffer, then I want to also do math on that same phasors output that produces a ramp that goes from 0 to 0.5, stays at 0.5, and then continues up to 1. I would like this "ramp, straight, ramp" to happen at the same frequency of the first phasor~, and I want to be able to specify the times of the "ramp, straight, and ramp"
    Here is how I'm doing it right now..

      also, I'm using this for granular synthesis, so I would like to avoid using Max objects and stick to MSP objects so everything is sample accurate.

      never mind! I figured it out.

      Always a good idea to post your solutions, so we don't have unanswered questions on the forums.

      I did this as an exercise - just to see how I might do it. I wonder what solution you came up with or if there is some perfect object or object combo that does this without all the gates~ and selectors~.
      anyways here's my attempt:

      Here's a quick n dirty Jitter-based solution that will save some audio processing power. It clicks like a bitch, so it's not so good for realtime PM, but it's cheap and sorta works...
      I'm not feeling very clever today, but I know there's a much tidier way of doing this with a single [jit.expr], rather than taking two ramps and smushing them together the way I've done here.
      I just realised this is like making a variable-width [kink~], innit?
      Butcher away and improve:

      Here's another way of doing it. This updates once per loop so you don't get weirdness when dragging.
      And PM.Scale~:

      Sorry fo the delay - I need to set up email notifications when I get replies.
      Here was my solution:
