Amplifier Section (VCA)
A voltage controlled amplifier (VCA) controls each synthesizer channel's
output. This allows manual control over the output volume as well as
dynamic volume progressions. Available modulation sources are the enve-
lope generator and a fixed gate-envelope, the latter offering minimal
attack- and release-phases to avoid unwanted clicks caused by disadvanta-
geous phase cuts during sound reproduction.
Every synthesizer channel has the following control elements:

MODE
This switch sets the modulation source for the VCA, respectively sets the
VCA to be opened permanently.
EG the ADSR envelope-generator modulates the VCA.
GATE ( ) a fixed organ-like envelope modulates the VCA.
ON the VCA is permanently on, no modulation.
The modulation intensity of the envelope generator can be controlled by
MIDI-velocity. This function can be enabled/disabled using EDIT PARA-
METER 4: VELOCITY, available for each synthesizer channel. To enable/
disable this function, carry out the following steps:
1. Press the EDIT-button.
2. Select parameter 4: VELOCIY using the SELECT/SEQ control.
3. Press TRIG to enable/disable velocity control for one or several syn-
thesizer channels. The corresponding red LED above each TRIG-
button will display the respective velocity-status.
4. Exit edit-mode by pressing the EDIT-button.
