One approach I like to take with ambient to get away from that robotic rhythm is to use the pitch CV information to add a little bit of adjustment to my clock. So for example, Pip Slope into Bloom, Bloom CV 1 into a buffered mult, one out of which goes into Surface, the second out of which gets attenuated through Tangle Quartet and sent back into the Pip Slope's decay CV. This will add a little pause after higher notes, and a shorter pause or perhaps none at all after lower notes. If you want the opposite, get an attenuverter instead of using TQ and invert the CV coming out of the buffered mult. You can also do this trick with your envelopes so that rather than modulating the tempo you're modulating the decay of the Surface, meaning the note itself will last longer or shorter depending.
Since it seems like you don't have a buffered mult at the moment you could use CV 2 on the Bloom instead of CV1 through a mult which might be interesting in its own way, not quite so clearly linked with what's happening sonically.
