THE EFFECT DEVICES

Creating a real dynamic wah effect with the envelope follower

As we have shown, you can get auto-wah-like effects with the Body section in Scream

4 (by using the Auto parameter). You could also use the ECF-42 envelope controlled

filter and trigger this with a gate signal - this is after all a “real” filter and sounds even

more like a wah effect. However, to get a “real” auto-wah effect that responds to the

signal level, you need to combine both these devices:

1. Create an instrument device that you want to process with an auto-wah.

It should be velocity responsive so that the harder you play, the louder it sounds.

2. Create a Scream 4 device and an ECF-42 device.

Both these should now be connected as insert effects to the instrument device.

3. Turn off all three sections in the Scream 4.

This is of course a matter of taste - but here we will show how to use the envelope

follower in Scream 4, not its sound destruction capabilities.

4. Flip the rack around and connect the Auto CV Output on the Scream to the

Freq CV input on the ECF-42.

5. Lower the pot next to the CV input a bit - the envelope follower is rather sen-

sitive and you probably don’t want the filter to open too much.

You can adjust this later if needed.

6. On the ECF-42, select the BP 12 (bandpass) mode and set the Res setting

rather high.

7. Play the instrument device and adjust the Freq setting on the ECF-42 to

taste.

As you can hear, the harder (or the more notes) you play, the more the filter will

open.

✪ If you find the auto-wah too responsive, you could add a compressor be-

tween the instrument device and the Scream 4 to even out the level dif-

ferences a bit.

✪ The Spider CV Splitter and Merger (see page 361) can be used to invert

and split the Auto CV output for even greater flexibility.

Scream 4 sample rate issue

Some of the algorithms on the Scream 4 Distortion device do not have the expected

effect when running Reason at a sample rate lower than 14 kHz (or exporting to a

sample rate lower than 14 kHz). Please use a higher sample rate if your song contains

Scream devices.

RV7000 Advanced Reverb

The RV7000 is a high quality reverb processor. It features nine different reverb and

echo algorithms, ranging from rooms and halls to special effects. Since the RV7000

comes with a number of useful reverb presets, you could simply select one and tweak

the most important parameters on the main panel - or you could use the Remote Pro-

grammer panel to fine-tune the reverb in great detail.

The RV7000 also contains an equalizer and a gate section. Both of these are for pro-

cessing the actual reverb sound, making it possible to get virtually any kind of reverb

character, including gated reverb.

About the Patch format

Like the Scream 4 device, the RV7000 features programmable effect presets. In the

Factory Sound Bank will find a number of preset Patches which can be used as they

are or provide you with a good starting point for further tweaking.

Patches use the Windows file extension “*.RV7”. Loading and saving Patches is done

in the same way as for instrument devices.

Connections

Typically you connect the RV7000 as a send effect, as this allows you to use it for

processing several different mixer channels. However, it’s also possible to use it as an

insert effect - use the Dry/Wet control on the main panel to adjust the balance be-

tween the dry, unprocessed sound and the reverb. Note:

D The RV7000 is a true stereo reverb, which means that it will use the ste-

reo input information when processing both channels (without summing

the input channels).

It’s also possible to use it as a mono in - stereo out effect. Which type of connec-

tion to use (mono or stereo in) depends on the material. If the audio sources are in

mono (or in stereo but with no important difference between the left and right

channel) using a mono input is sufficient.

D If you want to use RV7000’s Reverse reverb effect, you should consider

connecting it as an insert effect or using Send 4 on the Mixer, with Pre-

fader mode selected (and the channel fader lowered).

This is because you typically don’t want to hear the dry sound when using the Re-

verse effect. See page 349.
