Creating an siren with Radias?

roblof · Post by **roblof** » Fri Dec 12, 2008 7:47 pm

I need a slow siren like the one you can hear on american movies when someone escapes prison and the siren wails.

First I was thinking about sampling one but then I realized that this could probably be done with the Radias card that I have installed in my M3.

My problem is that I'm not used to analog synths and therefor only have barley basic understanding of how to work it.

Does anyone have some tips to share for this type of application?

Tnx,

LFO 1 Freq.=.2 Hz
LFO Wave=Triangle
VPatch1=LFO 1 to Pitch, Adjust intensity to set the range
Done.

To do a Euro style siren, set the LFO wave to square, with a freq. of 3 Hz.

Tnx!

It took some time to navigate the menues but I got it right eventually...

I added some distortion/cab sim + reverb and got what I wanted.

I have an follow-up question. Is it possible to extend this slow wailing siren so that is simulates the ambulance(?) siren that first go slowly like the suggested settings and then every now and then doing the fast wailing?

Do a second timbre for the fast wailing, then do a keyboard split. That way you can do the slow siren with one key on the left, then do the fast one with a key on the right side. You probably can do the same thing with one timbre, but it's more complex since you'll need to control EG3, LFO2, and virtual patches to control the timing of the alternating sound.
