modular ducker

hello, is it a bug that you can hear the sidechain signal when input to the sicechain input of a ducker module in modular III?

IT seems very strange, well maybe this would be needed in radio etc, but I dont want to hear the sidechain signal...hmm..

ok I could take a compressor sicechain instead....but I was wondering if the ducker has different curves...

I don't know if it has a different curve (I don't belive it's different anyway) but you could make a simple test loading one device for each type, connecting them one side to the same source and the other side to different channels of your mixer and then reading the meters.

Varying the level of the source you could control the response.

maybe you used wrong values for thresh and/or ratio? if Sci should totally supress In signal, use -60 for thresh, and inf:1 for ratio.

yes it does, but the signal fed to the sc input is audible, well, it gets mixed with the signal to be duck-ed

this is strange. when you load this patch, do you hear the synth sound when the vocal is played?

no, but the voice is audible

what a psychedelic patch

)

uhm, well, I dont always want to hear the signal which is used to control the dynamic of another. In the STM24/48 mixer you dont hear the signal either, which is fine, I was just wondering how the ducker would sound, but to my ear they sound at least very similar - so - its no big deal, my problem is just that the signal fed to the sc-in is being mixed to the ducked signal...well, it mixes it, when doing voiceovers this is fine, but not when experimentig with all kinds of ducking signals...

You could phase invert the signal going to the sidechain... just as a modular experiment.

I expected some phase cancellation approach in the patch from roy thinnes

but I tried it now and it cant work since the sc input is mono, and cancelling the voice by inversion of course gives complete silence

A ducker and a compressor have a totally different function, as explained in their manual. Apart from the basic parameters, they have a different routing.

Maybe that's causing your confusion? AFAIK, they both work just fine...

yes, I thought it wouldbe just that little different routing thing...I just wanted to try that modular ducker anyway...
