   "description" : "In this code, I have a list of frequencies. \r\nWhen I am calling \\synthexample, I provide some parameters, the usual ones (amp, etc) and other like bb and threshold.\r\nThe bb parameter is taken into account and works.\r\nAnd the threshold parameter is passed to a function which goal is to pick a frequency on a list of frequencies that is greater or equal to the threshold value. \r\nThe problem is that the threshold value is not taken into account. It works only if I pass to the function a litteral value, such as 200.\r\nAlso passing \\threshold.ir(100) raises an exception at Command+Enter time.\r\n\r\nSo how to pass a parameter to a function called inside a SynthDef ?\r\n\r\nThank you !",
