Method shiftLfoModulationTargets

Source/PluginProcessor.cpp:2492–2529

* @brief Shifts the band index for any LFO modulation routing target within a specified range. * * This function iterates through all modulation routings. If a routing's target parameter * has a band index between startIndex and endIndex (inclusive), it adjusts that index * by shiftAmount. This is crucial for keeping modulation assignments correct when bands * are added or removed. * * @par

 * @param shiftAmount The amount to add to the band index (can be positive or negative).
