In a new document:
1. Create a combinator (Right click, create- combinator)
2. Create a Mixer 14:2 inside the combinator
3. Create- create instrument- Reason Factory Sound Bank- ALL Instruments- Voice and Choir- Synthetic Mezzo FVox. Name this "Female Choir."
4. Change the mod wheel on the female choir synth to around half, I used 64 and set the portamento to "Auto" (this makes it so you can slur notes that overlap). Change the pan for the female choir on the mixer (should be chanel 1) to around -20 to -30, I used -22. Now on the Mixer there's an area that says "Bass" and "Treble", on the area that says "Trebble" turn the dial above to around 20, I used 18 then turn the bass dial to around -20 I used -18.
5. Create- create instrument- Reason Factory Sound Bank- ALL Instruments- Voice and Choir- Synthetic Tenor MVox. Name this "Male Choir." Use all the same settings as the Female choir except on the Mixer use the opposites. Example: the trebble dial should be -18 (or whatever number you used).
6. Turn AUX dials on the mixer to 127 on both chanels. Right click on the mixer- create- create effect- Reason Factory Sound Bank- ALL Effect Patches- Reverb- ALL DarkStrsHall.
7. On both the female and male choir synthesizers right click create- UN-16 Unison set the detune dial to around 60-70. Make sure the voice count is set to 16 and the Dry/wet dial is at 127 (these should be default settings).
and you're done! :)
