tricky one.
a) if you load up the fixed shifter and set voice 1 to +12, tempo to 1/4 and bump up the feedback, you'll get rising octaves at regular 1/4 note intervals
b) if you set voice 2 to +24, tempo to 1/4dot with some feedback, you'll get rising octaves, but with a slightly different rhythm than you're after
c) if you use two pitch blocks in parallel, you can use 4 voices with no feedback set to the rhythm you want, but the shifter only goes up to +24, so you won't get any octaves higher than that.
d) if you use two pitch blocks in series (in a parallel row, with the first set to 100% mix), you can set the first up like "b" above and the second at 50% mix with voice 1 set to +24, tempo to 1/8dot and zero feedback. again, not quite the pattern you were looking for, but another alternative.
once the pitch gets above +24, it's pretty hard to hear it, so i don't know if the rhythm of those later taps is all that critical. have a mess around and maybe you can find something that works for you
