I did something similar a number of years ago to allow tuning of ramping waveforms. I used a subArray with a length of one element and an adjustable index into the array to inspect the elements, and an aoRecord to adjust that element for tuning. The aoRecord wrote to a genSub record which recalculated the waveform (recomputing the rest of the waveform based on the new input and smoothing around the changed element to avoid discontinuities). The genSub then populated the waveform output record which controlled the hardware. As I recall, I needed to do some tricks with DISV to control record processing (run mode versus tuning mode) and to sync the aoRecord with the waveform element when not in run mode.
