Controlling the Preset Effect Amount from the Voice
The Proteus X allows you to control the Preset effects amount from the voice.
This means that the amount is individually controllable for each key press. With this
great feature you can create many wonderful effects such as:
•
Velocity or pressure controlled distortion on guitars, organs or electric pianos
•
Release velocity controlled echoes or reverb
•
Chorus or Flanger amount controlled by an envelope generator or LFO.
•
Ring Modulator or Pitch Shifter that only occurs during the attack.
Because the effect amounts are now controlled by your performance, this technique
contains endless possibilities. Try it!
How to Control the Effect Amount from the Voice
For this example, let’s set up the keyboard so that echoes only occur with low velocity.
When you hit the keys soft, you get echoes; when you play hard, you get no echoes.
1.
Select the preset you want in the tree by clicking on the keyboard icon. The
Preset Global page appears. (Choose a sound with a fast release for this example.)
2.
Click on the Effect Select icon at the top right corner of the Effects TV screen.
A list of available effects drops down.
Remember that if a
preset with effects is used
on more than one MIDI
channel, the CPU penalty
multiplies each time the
preset is used.
3.
Select Delay from the list. The Effect name is now listed above the TV screen and the
effect parameters are shown in the TV screen.
4.
Play the keyboard. You should now hear the echo. Adjust the parameters to taste.
5.
Turn up the Wet/Dry Mix to about 86% Wet.
6.
Select Voice Processing from the Tree for the preset you are using. The Voice Page
appears.
7.
Find an unused Cord and Set it up like this: Ve | -100% | Wet/Dry Mix
8.
Make sure the Wet/Dry Mix in the Amplifier section is set to 100 (all wet).
9.
Play the keyboard soft and hard to check it out.
10.
To reverse the action (hard = echo; soft = no echo), make the Cord amount +100
and set the Wet/Dry Mix to 0 . (You may also want to reduce the Wet/Dry mix in the
Echo effect itself to obtain the proper response.)
11.
Now that you’ve got it all set up, try changing the Preset Effect. Try reverb, flanger,
phaser and distortion effects.
