@yall Put all sync values in an array such as const var tempoValues = ["1/1", "1/2D", "1/2", "1/2T", etc...];
Then it depends if you use 2 different knobs (one for freq and another for sync values) or a single knob changing its properties (min, max, stepSize...)
In the knob callback, get the array index when in sync mode using the knob value for the label Label.set("text", tempoValues[value]);
