That’s true to an extent, but the locked delay is more of a glitch effect than a granular wash. Granular ideally needs overlapping grains, which have controllable amp envelopes.
It is possible to achieve something like this with sample retriggering and a short retrigger time, but the amp envelope does not get retriggered, so cannot modulate the individual grains. Just being able to enable retriggering of the amp envelope when retriggering the sample would be enough possibly.
It just occurred to me that I could use the LFO. I am going to try using the LFO to modulate the amplitude and sync it to the retrigger rate.
