i heard a lot about the 4-pole, but havn't had the chance to test it yet. i
talked to some guy at a music store and he told me, that filters, including
the 4-pole, arn't any good for bass-sound cause you wouldn't hear a lot of
differences at low frequencies. is that right ( i kinda don't believe this
if that's true, would there be any possipility to use filters with my bass,
for example split the bass signal, go through a pithch shifter into the
4-pole, then mix both signals and go into the amp... would that make any
i just want to have a clean signal mixed with the filtered signal cause i
think that the low bass sound is an essential part for the groove of the
(/my?) kind of music i make.

who else uses a waldorf 4-pole besides miko and dan? could you tell us your
experiences with it?
