Police Siren - Runaway Baby / Bruno Mars
Anyone have a patch for this police siren sound for the Kronos? Or simple programming tips?

Couple months ago I made a police siren in that style. It was part of an environmental sound. You can listen to it here: https://soundcloud.app.goo.gl/uiYKahEDUBuvG5zt8
Here are the notes for the client concerning the siren itself.
“It's a sine going through diode type asymmetrical distortion. The gain into the distortion is being modulated very slightly by the pitch EG for the sine (+2dB). That pitch EG has a modulation depth of 17 semitones from C#4 to F#5. The attack has a small convex curve and lasts 1.776 seconds. The decay lasts 3.808 seconds and is linear. No sustain of course. The envelope is retriggered every four bars at a tempo of 174.61bpm.”
You should be able to find EG times here on KorgForums. Just do a search, I posted them somewhere. Use MOD-7 to create the patch. Then put it through reverb to sound like the Runaway Baby intro.

Nice one, Charles.
MOD7 is my favorite engine.
@average_male
There are 2 parts to making the siren.
One is to get the pitch changing like a siren.
Charles' second tip about distortion just adds grit.
Here's a super quick guide to doing it yourself.
(From memory, not at Kronos atm):
1) From an INIT EXi, choose MOD7 as the engine.
- Common / Basic, engine type at top of page
2) Select the Osc1 tab.
- notice waveform is sine by default
- change this to Sine + waveshaper
- below this, in middle, touch the detune
- now notice in upper right you have Pitch mod options
- choose Pitch EG, amount to +17 (per Charles' tips)
3) go to Pitch EG tab
- follow Charles' settings
- tweak by ear
4) For the bit of distortion:
- go back to Osc1 page
- on bottom left is the Waveshaper section
- change the WS to Diode 1
- touch the Drive box
- notice upper right window now shows Drive mod options
- choose Pitch EG, amount +2dB (per Charles)
Good luck!
