LFOs’ sustain envelope mode’s sustain point isn’t stable. It sound like it’s looping a very short period of the LFO curve but I’m not sure what it does exactly. The sound changes on every new note. It’s the most noticeable with a short LFO time at points where the LFO has a slope. At flat parts it generally sounds as expected.
