!!WRONG, read the paragraph below!! If you put an LFO to Loop Hold mode and set the phase slider to hard zero the LFO phase jumps on key release. When you enter 0.001 as phase slider position the LFO phase doesn’t jump any more on key release.
Vital 1.5.5
Edit: I was wrong about this bug - it’s more complex. If one sets the phase slider near zero the LFO doesn’t loop, it just goes straight to release part. The faster the LFO is set to the further the phase slider needs to be set from zero to avoid this. You really start to notice this with LFO speeds at 1-20ms where you could set them to have a nearly instant response to key release.
Edited the title to match the bug.
