alright there, does anybody know the parts (oscillators, filters) - what effects what etc so i could try and recreate a siren with a software synth? once done id happily upload a sample pack. cheers, dave

Hi

What type of siren do you want to emulate? Are you talking about a dub siren like the one I created over here?

yeah thats the one... i run logic therefore vst plugins dont work. Could you spare the details of that plug in so I could have a crack at one myself or is it a bit hush hush. thanks

Hi

It's really no rocket science.
- Pick an oscillator (saw or square) or a sample playing oscillator loaded with an appropriate waveform (if you got some siren samples with a timbre you like)
- plug a low pass filter after it
- use an lfo (low frequency oscillator) to modulate the pitch of the oscillator

That's it.

- For more dub flavour run the thing through a delay.

Breaking it down into more detail is not possible without knowing the specifics of the software synth you are using.

Hope this helps..

Managed to figure it out thanks! I used a LFO generating a sine wave to "wobble" the siren as it rises and falls. Im about to create a sample pack of all of the different sirens i've made if anyone would like them and can give me a link to upload it to! Dave
