Hello,
The Q factor is very extreme in this algorithm along with some of the other H8000 algorithms. I just tested and this behavior is the same on the H8000. I would suggest not turning up the Q on this algorithm, or using a different algorithm. ModFilter is a good choice for a dual filtered delay.
The Vintage Delay algorithm loads with the LFO going very fast. Try turning the RATE parameter down to around 1-2 Hz.
