I have the same problem. Eventide told me that lag is because the pitchfuzz algorithm is very complex (fuzz, octave, delay) and it can't be resolved. If you find a solution please share it!

Sorry – there is no possible solution that we can see.

If you buy (say) a reverb box that has 6 different reverbs that are essentially different settings of the same thing, this will load very quickly.

If you have a box that has very many large, complex and different algorithms, these will take a fraction of a second to load. Because you love the sounds, you will probably allow for this.

One of the above is the H9.
