Quick/easy change octave up to octave down pedal

I'm in a bit of a weird situation here that I need help with. I've been playing bass forever but have only recently begun dabbling in pedals. I'm growing familiar with the MXR talkbox and now my band wants to do 24K Magic. Thing is, since I have the talkbox they want me to do the recorded intro to the song, which I can't do on my bass because I can't get high enough register. I need a sub-octave for the main bass part anyways so I've been looking at octave up/octave down pedals and the concensus around here seems to be that the Digitech Whammy and EHX Pitchfork are excellent for both.

Where my problem comes in is that I need to be able to switch from octave up to octave down within a few seconds and that's where I need help. The Whammy looks like I can set it to octave up/toe down octave down/heel down, which is great. It seems I can do something similar with the Pitchfork by adjusting the latch so when it's down I'm in the up octave, then when I step off it's down octave. I prefer the size of the Pitchfork, but if the Whammy is more reliable or handles that type of thing better I wouldn't be opposed to grabbing it.

 

Ooo, really? That's not a problem on the sub-octave, but I don't want that in the up-octave. I'll have to look into that, it would make my decision for me if true. Thanks!

 

You mean the up/dual/down switch, yes? I was thinking I wanna do the talkbox intro with only the up octave, no blend. Instead of switching to down octave for the rest of the song I can just play in a lower register and keep it on up octave. But I'd want a blend for the verses. Would that be something I could program through the latch function or would I need to turn the blend to 0 for the intro then bring it up for the rest of the song?
