Ideally, this algorithm is best used for stretching signals by very very long amounts. This version of paulstretch will take an ftable and loop through it, make it an ideal means for creating sustained pads. ]], ninputs = 0, noutputs = 1, inputs = { }, outputs = { { name = "out", description = "Signal output." }, } }
