The Effects of Reason 3.0: Knowing the Effects
To apply an effect to an instrument, you must right click on the instrument you want the effect on. So once you right click on the instrument in the rack, you go to "Create" then from RV7000 Advanced Reverb to PEQ-2 Two Band Parametric EQ are different effects that you can apply to instruments.
RV7000 Advanced Reverb

This is the simple version of the Advanced Reverb unit. You can load a patch by clicking on the open folder or save the settings if you want. Manually, you can manipulate the decay, High Frequency Dampness, and Equalization. The Dry-Wet knob edits the amount of effect placed on the instrument. If the knob is turned all the way to Wet, then it will be the maximum amount of the effect on it, if it is turned to Dry, there will be very little effect. If you want the advanced settings you can click on the triangle near remote programmer. Then the unit will look like this:

Now you can edit the algorithm, size, diffusion, etc., until you get the effect perfect.
Scream 4 Distortion

This is a much better distortion unit than the original D-11 foldback distortion in my eyes. You can control the damage and change to different types of distortion, use an EQ and edit the body of the distortion or you could load settings by clicking on the open folder button.
The Vocoder
Vocoders are used to make voices hit different notes than sung or make instruments sound much different. Listen to Eiffel 65's Blue, the voice is an example of vocoding in action. This effect is a really advanced because you have to do the routing of the cables yourself. If you don't know how to turn the rack around to see the cables, you simply hit the 'tab' button. So first you must create a synthesizer, but while you are right clicking to create it, hold down shift so it doesn't send to the mixer. Then right click on the synthesizer and create a Vocoder. Then hold down shift and create a sampling device such as Redrum and press 'tab' to turn the rack around and connect the left output from Redrum to the modulator input on the Vocoder. It should look like this:

Then you need to record and play the wav where you want it. Then you select the Subtractor and play on it while playing the song. It should vocode the wav you are working with. The front of the vocoder looks like this:

The band toggle is basically how many voices you want it playing. You can use the vocoder to be an equalizer as well and it has some options like other effects such as shift, attack, delay, dry-wet, etc. This effect can really add some flavor to a song.
