uiCombo: Custom Value Possible?

• while on the topic of uiCombo, also couldn't find anything on the uiComboDynamicContent property, it's purpose and how it might be leveraged.

As usual, any thoughts appreciated.

• tried a few things to no avail

name=value
name = value

• have several param sets that are non-contiguous & hoping to avoid the minutia in manually coding it
• If necessary, I suppose a workaround is to create an intermediary table to do the lookup before sending
• was also attempting this on CtrlrToggleButton controls, but never could figure it out

uiCombo selections for Filter Type

[ 0] Off = 0
[ 1] Classic = 4
[ 2] Smooth = 2
[ 3] Steeper = 6
[ 4] MegaSweepz = 1025

• Among the searches on ctrlr.org, found this thread that seemed to embody other info I found.
• this DID NOT work my experience so not sure if different mechanisms/properties now exist to enable such handling
• https://ctrlr.org/forums/topic/uibutton-onoff-values/

To do that you would simply put the value of the program change in the “button values” property field of the button like so:

Off = 32
On = 17

mim – I would try that, and ignore the fact for now that “Value for on state” etc does not reflect the hardcoded values you’re designating in the button values field.

in ctrlr if you want to assign fixed values (for things like combo boxes or non 1-127 knobs) just use a fixed image slider or combo box with the value name first and the actual value being sent next w/ the = between the two. ..

combobox values might be something like:
off = 0
on = 1
something else = 2

or something like when a knob doesn’t go from 0-127:
0=0
1=16
2=32
3=48
4=64
5=80
6=96
7=112

CtrlrCombo Integration Workaround

Provides custom value assignments in a CtrlrCombo object

Summary

• uiComboList displays a list of options to choose from but will only return a 0-based index of the option selected.
• The FIRST item in the list will return 0, the SECOND = 1, etc
• This implementation leverages a
  1. 'token parser' to extract value from selected item's text
  2. Enum/HashTable to translate value to its index in the ComboList
• Example: Clicking the LAST option will return [3]

#0 = | [0] - Off
#1 = | [1] - FilterSweep
#2 = | 3 = Formant
#3 = | [9] - Notched

• no user-assignable mapping is possible.

Getting value from a selection

-- Fetch selected text
local text = L(panel:getModulator("layer_filt_type_L1_15371"):getComponent():getComponentText())
-- Fetch data from text ( [###] ) using helper function
local value = GetStringBetween(text,"[","]")

-------------------------------------------------------------------------
---Get string between two specified chars/strings
---@param text string
---@param startChar string
---@param endChar string
---@return number|nil
function GetStringBetween(text,startChar,endChar)
    startChar = startChar or "["
    endChar = endChar or "["
    if ( text == nil) then return nil end
    local first = string.find(text,startChar,1,true)
    local last = string.find(text,endChar,1,true)
    if ( first ~= nil) and ( last ~= nil) then
        local value = string.sub(text,first+1,last-1)
        if ( value ~= nil) then
            return tonumber(value)
        end
    end
    return nil
end

Set modulator by data

• GIVEN: device's parameter id = 137

---lookup table/enum
---@enum LayerFilterType
LayerFilterType = {
            [127] = 0,
            [0] = 1,
            [1] = 2,
            [2] = 3,
            [132] = 4,
            [133] = 5,
            [134] = 6,
            [136] = 7,
            [137] = 8,
            [8] = 9,
            [9] = 10,
            [16] = 11,
            [17] = 12,
            [18] = 13,
            [32] = 14,
            [33] = 15,
            [34] = 16,
            [146] = 17,
}
--- translate a value to a ComboList index
-- given value of 137
local value = 137
-- perform lookup and reassign `value`
value = LayerFilterType[value]
-- assign value to modulator
mod:setModulatorValue(tonumber(value),false,false,false)

OnChangeHandler function

--@param mod CtrlrModulator
---@param value number: modulator value
---@param source number: where did change get called from
function OnChangeHandler(mod, value, source)
    local modName = L(mod:getName())

    -- parse modname to detect call from specific modulator so ONE function can handle many mods
    if (found ~= string.find(modName, "layer_filt_type_L1_15371", 1, true)) then -- true = plain text search
        -- Fetch selected text
        local text = L(panel:getModulator("layer_filt_type_L1_15371"):getComponent():getComponentText())
        -- Fetch data from text ( [###] ) using helper function
        local value = GetStringBetween(text,"[","]")
    end
end

Permutations of Calls

L(panel:getModulator("layer_filt_type_L1_15371"):getComponent():getComponentText())
L(layer_filt_type_L1_15371:getComponent():getComponentText())
