Space Designer density envelope in Logic Pro for iPad

Density envelope parameters

• Density Envelope On/Off button: Turn on or turn off the density envelope.

• Init Density knob and field: Set the initial reverb density (the average number of reflections in a given time period). Low values result in audible reflection patterns and discreet echoes.

• Ramp Time knob and field: Adjust the time between the initial and end density levels.

• End Density knob and field: Set the density of the reverb tail. An End Density value that’s too low can result in a grainy sounding reverb tail. The stereo spectrum may also be affected by lower values.

• Reflc Shape slider and field: Determine the steepness (shape) of early reflection clusters as they bounce off the walls, ceiling, and furnishings of the virtual space.

  Low Rflc Shape (Reflection Shape) values result in clusters with a sharp contour. High values result in an exponential slope and a smoother sound. This control is particularly useful when recreating rooms constructed of different materials. When used with suitable envelope, density, and early reflection settings, you can create rooms of almost any shape and material.
