1) No, the H9 has the same features as the Factor pedals…. Assuming you purchased all the algorithms … So an H9 with all the PitchFactor algorithms purchased is the same as a PitchFactor. Only exception is TimeFactor … The H9 is missing the Looper feature at the moment… It is in development.
3) if you need the 3 switch the Digitech one is popular, also this1smyne makes them too… There are also MIDI options if you want more complexityz
You've got an app, called H9 Control, that you can download on the Eventide site for free, or on the appstore if you have an iPad, iPhone or iPod. When you have this app, you can see all the algorithms into your H9, try them for a few minutes then buy them if you need it. Paiement via appstore or Amazon. 19$ the algorithm.
