Randomize Sculpture morphs in Logic Pro for iPad
The randomize feature creates random variations of selected morph points. When combined with the copy/paste functions, randomizing lends itself to using the Morph Pad as an automatic sound generator.
Use of the Morph Pad can yield interesting composite sounds—hybrids of the original and morphed sound. You can copy this hybrid sound to a corner of the Morph Pad, or to multiple corners, and randomize it by a definable amount. The morphed sound then becomes a new timbral element that can, in turn, be moved to the corners, randomized, and so on.
In effect, you’re “breeding” a sound, while maintaining some control by selecting parent and child sounds. This approach can result in new, complex sounds—even if your sound programming knowledge is limited.
Morph Randomize parameters
Random Group pop-up menu: Limit the type of morphable parameters that are affected by randomization.
All morphable parameters: Randomizes all parameters in the following groups, which can lead to unusual sounds. This can lead to some interesting results, but it is uncontrolled, making it unsuitable for the “sound breeding” idea.
All except TensMod: Identical to All morphable parameters, but excludes the TensionMod parameter from randomization.
String Material/Media: Includes the Material Pad position, Stiffness, Inner Loss, Media Loss, Resolution, and Tension Modulation parameters for randomization.
Objects&Pickups: Alters the positions of objects and pickups, plus various object parameters, when randomization is used.
Waveshaper&Filter: Alters the positions of all Waveshaper and filter parameters when randomization is used.
Random Point pop-up menu: Choose the morph points (or edges) you want to randomize.
RndInt knob and field: Set the amount of randomization from 1% (slight deviation) to 100% (completely random values).
Random Trigger button: Create randomized values for all parameters of the chosen morph points.
Randomize morph points in Sculpture
This example provides a general approach you can follow for morph point randomization.
In Logic Pro, tap a Morph Scene button (Cen(ter), A, B, C, or D).
Tap the Auto Select button.
Set the RndInt (Random Intensity) knob to a value of 25%.
Tap the Random Trigger button.
Drag the gray dot to each corner in the Morph Pad. Do this along the edges and through the center of the Morph Pad.
Note how this affects the morph.
Strike a few notes on your MIDI keyboard while dragging the gray dot.
Note that positions on the Morph Pad that fall in between the various morph points cause the randomized parameters to interpolate between values. You can use the Copy and Paste commands to make use of these in-between values.
