• Envelope Type pop-up menu: Choose the envelope type. This alters the number and
appearance of envelope parameter fields and the graphical envelope display.
• Attack handle and field: Drag horizontally to set the time it takes for the envelope to
reach the initial level. Drag the field vertically.
• Hold handle and field: Drag horizontally to set the time the full level is held, following
the attack phase, before the decay phase begins. Drag the field vertically.
• Decay handle and field: Drag horizontally to set the time it takes for the envelope to
fall to the sustain level, following the hold phase or the initial attack time. Drag the
field vertically.
• Sustain handle and field: Drag vertically to set the sustain level, which is held until
you release the key. Drag the field vertically.
• Release handle and field: Drag horizontally to set the time it takes for the envelope
to fall from the sustain level to a level of zero. Drag the field vertically.
• Vel slider: Set the intensity of filter envelope modulation in response to incoming
velocity data.
• If the Vel slider is set to zero, the envelope outputs its maximum level when you
strike the keys at any velocity.
• At a Vel slider value of 100%, the entire dynamic range is under velocity control.
To explain, raising the slider value reduces the envelope minimum amplitude, with
the difference being dynamically controlled by keyboard velocity. For example, when
you set the Vel slider to 25%, the minimum envelope amplitude is reduced to 75%.
The remaining 25% is added in response to the velocities of keys you play. A key
played with a zero velocity results in an envelope amplitude of 75%. A key played
with a MIDI velocity value of 127 will result in an envelope amplitude of 100%. When
you raise the Vel slider value, the minimum amplitude decreases even further.
MainStage Quick Sampler filter types
Quick Sampler provides multiple filter types you can choose in the Filter controls. Each
filter type has unique sonic characteristics and responds differently to incoming signals.
This flexible collection of filters enables you to subtly or dramatically sculpt the tone of
your instruments.
Quick Sampler filter types
• Lowpass (LP): This filter type passes the portion of a signal below a specified cutoff
frequency and rolls off the portion above that frequency.
• Bandpass (BP): This filter type passes the portion of a signal occupying a band
surrounding the cutoff frequency and rolls off the portions above and below that band.
• Highpass (HP): This filter type passes the portion of a signal above a specified cutoff
frequency and rolls off the portion below that frequency.
• Band reject (BR): This filter type cuts a narrow band around a resonant frequency. The
remainder of the signal is affected minimally.
• Peaking: This filter type boosts a narrow band around a resonant frequency. The
remainder of the signal is affected minimally.
