Beat Repeat Pitch (Up and Down)

I just watched the great little Beat Repeat movie and was wondering why the Pitch knob only pitches down. Why not have it's control centered (like a pan) and offer to let the user pitch up or down?

Thanks,

people have talked about this alot. basically it isn't possible with the way it reads the audio because it would technically have to read ahead in time because pitching up would cause the beat repeating to go faster than the original audio. there are however plugins that work in different ways, loading the sound into memory as if it was being sampled in real time, in which case it could pitch up and loop tiny fragments (without having to look ahead in time, because it was repeating the portion of your audio that it sampled) where as beatrepeat isn't doing any "sampling"(sampling being used in the sense of recording and playing back as in a dj might use)

personaly I think they will eventually modify beatrepeat to make it possible to pitch up. but it will take a total revamping of the plugs whole concept I believe. I also read that they will eventually have other plugs such as "beatstretch" and what not...

Interesting, thanks for the explanation. I suppose if it was a granular setup, it could repitch up without reading ahead, right? Just no time compression with the repitch.

It is not necessarily a feature I need, it just seemed like something missing.

wait a second here, it's beat *repeat*

so you have

[beat][some time][rep][rep][rep]...
so if the knob is at the middle (or max as it is now) it would go

[beat][some time][beat][beat][beat]...

but if you would pitch UP...
by the time the first repetition would take place, the part of the beat needed to pitch up would have *already happened*.
So there's no magic!
just make your code smarter guys

btw
even if you repeat your beat right after it has happened... like this

[beat][rep][rep][rep]

and you wanted to pitch it up, lessay the pitched up beat equals [beat]+[some more after the beat]

then you have

[beat][beat(pitched up)][**some more after the beat (pitched up)] in terms of what's output

OR
in terms of what's input into the plugin
[beat][some more after the beat][(here starts the pitched up part**)]

so again
there's no magic
perhaps you'd only have to limit the "pitch up" feature by what's possible
cause lessay - if you have a 1 sec long beat
and then a repeat right after that
and you pitch it up to 200%
then you have
[beat(1sec)][beat(1/2 sec - pitched up)][stuff after the beat]
so the stuff after the beat would be at 200% too.
but, as we can clearly see, it would be sourced from only 1/2 sec of material
so in the end we only gain 0.25 sec of "pitched up" material

alternatively
why not just make the pitched up beats shorter?
c'monnnnnnnnnnn that's so cheap. don't tell me you can't do it.
