;; (record-buf bufnum offset reclevel prelevel run loop trigger inputs)
;; Records input into a Buffer.
;; If recLevel is 1.0 and preLevel is 0.0 then the new input
;; overwrites the old data. If they are both 1.0 then the new data is
;; added to the existing data. (Any other settings are also valid.)
;; bufnum - the index of the buffer to use
;; offset - an offset into the buffer in samples, default 0
;; recLevel - value to multiply by input before mixing with
;; existing data. Default is 1.0.
;; preLevel - value to multiply to existing data in buffer before
;; mixing with input. Default is 0.0.
;; run - If zero, then recording stops, otherwise recording
;; proceeds. Default is 1.
;; loop - If zero then don't loop, otherwise do. This is
;; modulate-able. Default is 1.
;; trigger - a trigger causes a jump to the start of the Buffer.
;; A trigger occurs when a signal changes from <=0 to >0.
;; inputArray - an Array of input channels
