   "description" : "This gradually changes the tempo of a TempoClock, each beat of a specified number of beats, and starting at the next bar.\r\n\r\n\r\nPersonally, I was not able to heavily distinguish between `.linlin` and `.linexp` for reasonable musical tempos.\r\n\r\n\r\nThere may be a mathematically smoother way of handling this at the control rate.\r\n\r\n\r\nThis function does not gracefully handle multiple simultaneous invocations."
