SCREAM 4 SOUND DESTRUCTION UNIT570
Emulating vintage digital gear
The first generations of digital instruments (drum machines, synths and samplers) used 8 or 12 bit sampling and pro-
cessing, at low sample rates. This “lo-fi” sound is still in high demand, e.g. in hip-hop and R’n’B. Try this:
1. Connect a Scream 4 as an insert for a Redrum, with a suitable kit selected.
2. Set Damage Type to Digital and turn P1 and P2 fully right.
3. Play back and lower P1 (bit depth) and P2 (sample rate) to get the sound you want.
You may also want to use the Cut section to emphasize or cut frequencies in the sound.
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 param-
eter). 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 sig-
nal 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 sensitive 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.
q If you find the auto-wah too responsive, you could add a compressor between the instrument device and the
Scream 4 to even out the level differences a bit.
q The Spider CV Merger and Splitter (see “Spider CV Merger & Splitter”) can be used to invert and split the Auto
CV output for even greater flexibility.
