Adding Aftertouch
Aftertouch is a performance feature that allows you to add modula-
tion to a sound by applying additional pressure to a key after the key is
already down. The greater the pressure applied, the more modulation
is applied. The TEO-5 provides monophonic (or “channel”) aftertouch,
which means that applying pressure to any key within a chord will apply
modulation to all notes currently held.
The Mod Matrix lets you choose the amount of modulation applied
using aftertouch and also which parameters are modulated (oscillator
frequency, lter frequency, sand so on). You can set either a positive or
negative amount.
For example, if you select the lter cutoff as modulation destination
(cutoff), set a positive amount of pressure, then push a key down harder,
the lter cutoff frequency will increase, making the lter open wider and
the sound become brighter.
Conversely, if you select the lter frequency as destination, set a nega-
tive amount of pressure, then push a key down harder, the lter cutoff
frequency will be lowered, making the lter close more and the sound
become more muted.
To choose aftertouch (pressure) as a source for modulation:
1. Press the mod button. The Mod Matrix appears in the display.
2. Use the select knob to scroll through the various mod sources and
choose pressure. (As a shortcut, hold down the src assign button and
press a key repeatedly to toggle through the available key-related mod
sources.)
3. Use the value knob to scroll through the various mod destinations and
choose a parameter (such as cutoff).
4. Hold down a note on the keyboard. Then, press harder.
5. Hold a note and move the Pitch wheel to hear the effect.
6. Use the value knob to set the amount to your preference. Higher
amount settings add greater modulation the harder you press a key. A
negative amount setting will apply modulation in the negative direction.
