This is a drool inducing thread.
So, the H9 is obviously the business. On the gig, is it easy enough to cycle through presents between songs?
The H9 may just might be my dreamgirl pedal.
The H9 is good as it can have all of the patches from all of the factor pedals - including the newly released looper algorithm from the time factor - in addition to algorithms that are exclusive to the H9. So if you get a newly release H9 MAX you can have all of the factor algorithms including any future released algos. The set back with the H9 is that you can only use one algorithm at a time. So for preset 1, you can have a chorus, preset 2 can be octaver, 3 delay, etc., however if you want octave with reverb or phase with delay, you need more H9s or another pedal.
If you were to get a second H9, such as a H9 Core, you would have all of the algos that are included with your original H9, so both pedals would have access to those.
I have an H9 and a Pitchfactor. The PF can act as the midi controller for the H9, and I have used it that way. Takes some setting up to do use it that way, but you don´t necessarily need a separate midi program change pedal to cycle through the presets if you have an H9 with another factor pedal. I think other midi capable units such as the Lin6 M series can also act as midi controllers.
I agree with Adam, if you are only going to go for one H9, it is best to also use an aux switch such as the digitech FX3 as this makes cycling through the presets much easier. If you are going to use a pitchfactor or any of the PF algorithms, it is also highly recommended to use an expression pedal.
