How can I randomize an interval of time like the period of a pulse LFO every 15 seconds say by ± 10%
In other words instead of a totally regular pulse train every 15 seconds, get something like 14.9 sec, then 15.0, then 15.1, then 14.95 etc but still to average out long term to 15 seconds? Any easy way to dither this with some kind of noise chop etc?
