If you bought an H9, that already comes with the PitchFactor algorithms H910/H949 and Crystals. Plus, it comes with a coupon that you can use to get an additional algorithm of your choice free. So, if you wanted all of the remaining 8 PitchFactor algorithms, you could use your coupon for one and buy the remaining 7 for $140.
Adding all of the PitchFactor algorithms would give you all of the sounds of the PitchFactor. The interface on the stompbox is different of course, but the algorithms are identical.
