Any tips for an "audio pitched down" device?

["Per Boysen" <per@boysen.se>]

Hi,

Can someone recommend a good device for bringing the audio signal down
one or two octaves?

I'm not interested in midi or hexaphonic guitar pickups as I want to
transpose any audio source, not only guitar. Today I'm creating bass
lines with the Repeater by pitching a track down, but I'm finding this
strategy too slow in some musical situations. The best solution would be
something that simply brings the audio down in pitch (without inducing
latency) before it reaches the loopers. Then I could also use the EDP
for bass lines as well as fading bass in and out with the feedback
control. 

Long ago I owned some kind of "octavider" and this thing was actually ok
IMO even for saxophone and voice, but unfortunately it disappeared when
I lent it to a friend.

Best wishes
