Hi. I have 3 fader controls in a preset that have a dual function depending on the value of a particular list control. Specifically, I need to change the range of the 3 faders and also display a different set of labels. I have the setRange part is working nicely. But can’t get the alternative labels to display. I thought this would work, and the code runs without error, but the alternative labels do not display. Here is my code. I wonder if anyone can see what I am doing wrong. I’m thinking perhaps the pot ref# is not the overlay Id as I am assuming. Thanks ```auto function showNotes() -- Range and Overlay for the Delay and LFO4 fader's note duration options when midi synced local syncMode = parameterMap.get(deviceId,PT_NRPN,764) -- Midi sync mode local control1 = controls.get (110) -- Delay1 level fader local ctrlValue1 = control1:getValue ("value") local control2 = controls.get (114) -- Delay2 level fader local ctrlValue2 = control2:getValue ("value") local control3 = controls.get (74) -- LFO4 frequency fader local ctrlValue3 = control3:getValue ("value") -- a list of labels for the 10 note duration options when Delay1 or Delay 1+2 are midi synced local NoteDurationList1 = { { value = 0, label = "1/16D" }, { value = 1, label = "1/8D" }, { value = 2, label = "1/4D" }, { value = 3, label = "1/16T" }, { value = 4, label = "1/8T" }, { value = 5, label = "1/4T" }, { value = 6, label = "1/16" }, { value = 7, label = "1/8" }, { value = 8, label = "1/4" }, { value = 9, label = "1/2" } } -- a list of labels for the 12 note duration options when LFO4 is midi synced local NoteDurationList2 = { { value = 1, label = "1/1" }, { value = 2, label = "1/2" }, { value = 3, label = "1/4" }, { value = 4, label = "1/8" }, { value = 5, label = "1/16" }, { value = 6, label = "1/32" }, { value = 7, label = "1/4T" }, { value = 8, label = "1/8T" }, { value = 9, label = "1/16T" }, { value = 10, label = "1/4D" }, { value = 11, label = "1/8D" }, { value = 12, label = "1/16D" }, } if syncMode == (2 or 6) then -- midi synced Delay1 ctrlValue1:setRange (0, 9,0, true) overlays.create(110, NoteDurationList1) elseif syncMode == (3 or 7) then -- midi synced Delay1+2 ctrlValue1:setRange (0, 9,0, true) ctrlValue2:setRange (0, 9,0, true) overlays.create(110, NoteDurationList1) overlays.create(114, NoteDurationList1) elseif syncMode == (1 or 5) then -- midi synced LFO4 ctrlValue3:setRange (1, 12,1, true) overlays.create(74, NoteDurationList2) else -- not midi synced ctrlValue1:setRange (0, 127,0, true) ctrlValue2:setRange (0, 127,0, true) ctrlValue3:setRange (1, 127,1, true) end end ``` ---

I’m not sure the syntax: ```auto if syncMode == (2 or 6) then ``` is doing what you think. Try: ```auto if (syncMode == 2) or (syncMode == 6) then ``` ---

Thanks. I obviously hadn’t tested all the values of syncMode 🙂 . I made those changes. Nonetheless, while the ranges and labels change as expected (eg., 0-127 becomes 0-9) from teh setRange command. The labels do not change from the next overlays.create command. So I must have that command setup incorrectly. ---

yes - you’re missing the part about setting the overlayId with a value object. Take a look in the on-line docs in the Preset Lua Extension section under value. Since you have the control object (control1, control2, etc) you can use something like value1 = control1:getValue(“value”) and then value1:setOverlayId(110) (or whatever). Again - check the docs and example and give it a try ---

Ah. I see. Thanks! This code seems to work as expected: ```auto function showNotes() -- Range and overlay when midi synced local syncMode = parameterMap.get(deviceId,PT_NRPN,764) -- Midi sync mode local control1 = controls.get (110) -- Delay1 level fader control local control2 = controls.get (114) -- Delay2 level fader local control3 = controls.get (74) -- LFO4 frequency fader local ctrlValue1 = control1:getValue ("value") local ctrlValue2 = control2:getValue ("value") local ctrlValue3 = control3:getValue ("value") -- labels for the 11 note duration options when Delay1 or Delay 1+2 are midi synced local noteList1 = { { value = 0, label = "1/16D" }, { value = 1, label = "1/8D" }, { value = 2, label = "1/4D" }, { value = 3, label = "1/16T" }, { value = 4, label = "1/8T" }, { value = 5, label = "1/4T" }, { value = 6, label = "1/16" }, { value = 7, label = "1/8" }, { value = 8, label = "1/4" }, { value = 9, label = "1/2" }, { value = 10, label = "1/1" } } -- labels for the 12 note duration options when LFO4 is midi synced local noteList2 = { { value = 1, label = "1/1" }, { value = 2, label = "1/2" }, { value = 3, label = "1/4" }, { value = 4, label = "1/8" }, { value = 5, label = "1/16" }, { value = 6, label = "1/32" }, { value = 7, label = "1/4T" }, { value = 8, label = "1/8T" }, { value = 9, label = "1/16T" }, { value = 10, label = "1/4D" }, { value = 11, label = "1/8D" }, {value = 12, label = "1/16D" } } overlays.create(1000, noteList1) overlays.create(1001, noteList2) if (syncMode == 2) or (syncMode == 6) then -- midi synced Delay1 ctrlValue1:setRange (0, 10,0, true) ctrlValue1:setOverlayId(1000) elseif (syncMode == 3) or (syncMode == 7) then -- midi synced Delay1+2 ctrlValue1:setRange (0, 10,0, true) ctrlValue2:setRange (0, 10,0, true) ctrlValue1:setOverlayId(1000) ctrlValue2:setOverlayId(1000) elseif (syncMode == 1) or (syncMode == 5) then -- midi synced LFO4 ctrlValue3:setRange (1, 12,1, true) ctrlValue3:setOverlayId(1001) else ctrlValue1:setRange (0, 127,0, true) -- reset range to default ctrlValue2:setRange (0, 127,0, true) ctrlValue3:setRange (1, 127,1, true) ctrlValue1:setOverlayId(0) -- reset overlays to default ctrlValue2:setOverlayId(0) ctrlValue3:setOverlayId(0) end end ```
