How can a Picker be triggered in a non-sequential manner?

Question

MIDI Target Manufacturer(s): Other/Unlisted Maker

Is it possible to create a nonsequential picker? In the attached image, Buttons 1, 2, and 3 work normally when tapped. Btn 1, Btn2, and Btn3 trigger different  combinations of Btn 4 thru Btn 10. The Up and Down buttons cycle through each of its subcontrols sequentially via the Picker. This all works as expected.

However, I would like to trigger Buttons 1, 2, and 3 independently from another button (Step 1 to trigger 1, Step 2 to trigger 2, and Step 3 to trigger 3). The current layout has Step 1 as a Supercontrol to 1, Step 2 as a Supercontrol to 2, and Step 3 as a Supercontrol to 3. But that does not provide the same behavior when Step 1, Step 2, or Step 3 are tapped. In addition, the Picker does not change.

For example, when Step 1 is pressed and held, it illuminates and 1 and its subcontrols illuminate. When I release, all buttons associated with 1 will extinguish. The picker stays at its current position.

Is there a way to control 1 (or 2 or 3) from buttons that will force the picker to 1 (or 2 or 3), deactivate the current active buttons, activate the buttons associated with 1 (or 2 or 3), and leave the associated buttons active at the new position? In other words, if the picker is at tick 3 and Step 1 is pressed, the picker should go to tick 1 and button 1 will activate as if it were tapped directly. 

I am attaching the layout file.

Thanks, Don

Answer 1

Need to diagram your supercontrol / subcontrol relationships

In MDP2 help, and in my Masters Class layout are the answers to subcontrol scaling, which will show how to access a specific value.

But that is not the problem in your layout.  Diagram the flow of your relationships, and you should see the problem.  You need a top to bottom flow for the super / sub relationships to work, you are trying to drive backwards into the picker.  

Redirect steps 1, 2, 3, to point at the picker.  Assign midi values of 48, 96, and 127, and this will work.  (These values from subcontrol scaling above).

You still have 1, 2, and 3 driving backwards to the picker.  This will work for small numbers of buttons, but for a larger number of stops, they will get out of alignment at some point.

Thanks for your quick response. I am anxious to complete my latest layout and I needed to know how to configure the buttons and picker. Can you provide a link to your Masters Class?

I have used the connections you have drawn in blue for many layouts and have learned to avoid alignment issues by proper defining the number of ticks. There is no way to reverse the flow of 1, 2, and 3 into the picker and obtain the behavior I need. I need 1, 2, and 3 to be selected sequentially via the Up and Down buttons or, alternately, selected manually (i.e, out-of-sequence).

Btn 9, 1, 2 and 3 select variable combinations of Btn 4 thru 10. They also provide isolation from manually selecting Btn 4 thru 10 and not impacting C, 1, 2, or 3. This I learned through a lot of trial and error.

As far as the green, yes it was not working. But you gave me a clue on how to trigger the picker to one of its values. Steps 1, 2 and 3 I now have as Super to the picker. For 4 ticks, the values are 0, 42, 85, and 127.  So I set the Midi Off -> On value to 42 for Step 1, 85 for Step2 and 127 for Step 3. Everything works as I intended. The intent is Steps 1, 2, and 3 will be triggered by external hardware switches in my final layout.

Thanks, Again.
