Logic Pro Quick Sampler Amp controls
Quick Sampler Amp controls set the level, pan position, and polyphony.
You can control the level over time with a dedicated multimode envelope. Parameters that
are modulation targets are indicated by a white dot when a note is played. The modulation
range is shown as an orange ring around target parameters.
If you’re new to synthesizers and the concepts behind envelopes, see Synthesizer basics
overview.

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
