Output a sine wave from the filter
1. In MainStage, switch the Sub knob to Off.
2. Drag the Mix slider to the very bottom (Sub).
3. Drag the Resonance slider to the maximum position (full).
4. If you want, click the disclosure triangle at the lower left to open the extended
parameters, then click the Filter Boost button.
Filter Boost increases the output of the filter by approximately 10 decibels, making the
self-oscillation signal much louder.
MainStage ES1 amplifier parameters
The parameters in the ES1 Amplifier section allow you to fine-tune sound level behavior.
These are separate from the global Out Level parameter, which acts as the ES1 master
volume control. See MainStage ES1 global parameters.
Amplifier parameters
Level via Vel slider: Determine how note velocity affects the synthesizer level. The
greater the distance between the arrows (indicated by the blue bar), the more the
volume is affected by incoming velocity messages.
Drag the upper arrow to set the level when you play hard (velocity=127).
Drag the lower arrow to set the level when you play softly (velocity=1).
To simultaneously adjust the modulation range and intensity, drag the blue bar—
between the arrows—and move both arrows at once.
Amplifier envelope selector buttons: Determine the ADSR envelope generator used for
control of the amplifier envelope. See MainStage ES1 envelope parameters overview.
