I wounder how bipolar modulator is faster than uni modulator.

thanks in advance

it's because your are offsetting and scaling the oscillator. The bipolar cosine wave's range is -1. to 1. and the offset unipolar version is 0. to 1. Think of the 0. to -1. curve as positive, and you'll see that its frequency is indeed twice that of the unipolar. Here's a description and possible 'solution', using the [abs~] object [EDIT - don't use abs~ use *~]:

. . . . a more experienced synthesist/sound engineer will soon chime in, describing the mathematical, and the subjective, difference between positive and negative modulation of amplitude, and its effect on the frequency spectrum.

Bipolar cancels the centre frequency; unipolar does not, but shifts the sidebands. I don't like the [abs~] version, as it introduces far too many additional sidebands.
