Logic 9 How to assign inc/dec midi messages

    EDIT: My initial idea presented was wrong. Se my post below (from 2016) to see the EASY way to do this.

    Got a Doepfer pocket Dial and thought it would be cool to use inc/dec values (CC96 and 97?) to change parameters in Logic. The EQ for example.

    So I touched ChannelEQ/Frequency1, hit Command L, and turned a dial on the Doepfer.
    Parameter was assigned to the knob. But only in one direction it seems. When I turn the knob the other way nothing happens.

    Guess I'll have to adjust something in the Controller Assignmnents page in Logic but I can't figure out how.

    The "Format" parameter was probably not learned correctly.

    In Controller Assignments (Expert View) check the "Value" settings in the lower right area. I don't have an encoder here but so far I remember the settings should be as below.

    Min/Max: 0-127
    Format: Unsigned
    Multiply: 1.00
    Mode: Relative

    Format and Mode are crucial for the function, Min/Max and Multiply can be adapted to your needs.

    Here is your manual:

    Thanks, now I get it.
    The trick is to assign ONE knob to TWO controller assignments and edit the Multiply parameter.

    Example (Channel EQ - Peak2 Frequency):
    Increment (that is turning knob clockwise) I assign:
    CC#96 16 to Peak2 Frequency, Multiply set to 1,00

    Decrement (turning counter clockwise) I assign:
    CC#97 16 to Peak2 Frequency, Multiply set to -1,00

    The crucial thing is to set Multiply to positive for CC#96 and negative for CC#97 and always set the CC value (16 in this case) to the same plugin parameter parameter (Peak2 Frequency in this case).

    Thanks for the help.

    By the way is there a way to make the right plugin window to "pop up" according to the parameter being edited?

    Like if I assign some knobs to EQ and some to Compressor I could make the right plugin showing up only by turning a corresponding knob?

    Or more. You can allow 1, 2, 4 or 8 controllers for one parameter, this is a global preference:
    Logic Pro > Preferences > General > Control Surfaces
    Logic Pro > Preferences > Control Surfaces > Preferences

    The Min/Max and the Multiply values are unfortunately the only parameters to shape the response. In Logic X this problem is solved by the new "Smart Controls" where you have a graphical interface with a couple of editable curve forms. Very good approach.

    I don't know.

    Accidentally I found this old thread of mine and I might add that I completely misunderstood how to use the Doepfer Pocket Dial in conjunction with Logic. Although I obviously found a workaround there's a much better way.

    By using preset 111-114 on the Pocket Dial (consult the manual) it's really easy to assign controllers using learn. No nead to tweak inside the controller assignments window. The inc/dec-messages I suggested was obviously not the right ones for Logic.

    I might add, it works very well! Partly because of the excellent acceleration feature in pocket Dial.
