Hi.

So, I want to use the wonderful Hilbert Transform Bode shifter from the Kyma 6.4 prototypes.

I would like to send the signal shifted and then delay the unshifted signal and mix them back together. I'm using the formula ((numberTaps - 1)/ 2 + 1) samp , and a Comb Delay. But I'm finding that its kind of phase shifting the two signals against each other, like the delay is not fixed or something.

Any ideas?

Hi Cristian

Did you realize that the right output channel of the Hilbert transform module gives you the unshifted delay you need. You can use two channeller modules to pull them apart.

There is a limit to the number of taps (1051) and if you request too many it will limit it for you, hence if you use the formula and a delay module to make the matching delay, the delay will end up being too long.

hope it helps

Ah.. no I didn't now the module output both unshifted and shifted at the same time.. Thankyou.
