I'm afraid that my earlier explanations were correct. This means that it will not be trivial to speed up the response, and there is little point spending time to confirm this.
Note that H9 and recently manufactured 'Factors are faster than earlier 'Factors by about 30%. H9 is significantly faster than TF, but you lose the DSP+FX delay spillover.
When we made the initial design decisions for these pedals, people were not using MIDI for demanding control of stompboxes as they do currently, so our focus was more on sound quality rather than MIDI response.
We will keep this in mind and do what we can, but it is not as simple a thing as some would imagine.
