Quick Sampler Mod Matrix pane in Logic Pro for Mac

You can assign Quick Sampler LFOs and envelopes as modulation sources or targets in the Mod Matrix pane.

You can also assign your keyboard modulation wheel, aftertouch, pitch bend, velocity, and MIDI continuous controllers as real-time control sources for Quick Sampler target parameters in the Mod Matrix pane.

In the Mod Matrix pane:

1. Choose a modulation target from the Target pop-up menu.

2. Choose a modulation source from the Source pop-up menu.

   As an example: Use Velocity Inverted to modulate a target with a soft keystrike, and no modulation when struck firmly.

   Note: The envelope modulators shown in the image are hard-wired to control Pitch, Filter, and Amplitude, but you can also assign them as sources to modulate other Quick Sampler parameters in the Mod Matrix pane. The envelopes and LFOs are also available as modulation targets.

3. Set the maximum value or intensity of modulation with the Amount slider.

The Sample Start & End, Loop Start & End, and Loop Position targets can be quantized in musical values. For example, if you modulate the loop position (the entire loop) using an LFO, a quantization of one bar moves the loop back and forth along the time line in one bar increments instead of the usual smooth LFO motion.

You could also choose to assign your keyboard modulation wheel as a real-time control source for Loop Position, or perhaps to Sample Start or Loop Start, providing you with direct, physical control of these parameters.

In the Mod Matrix pane:

1. Choose an LFO from the Source pop-up menu.

2. Choose a Sample Start or End, Loop Start or End, or Loop Position option from the Target pop-up menu.

   The quantization value you choose in the modulation Target pop-up menu applies to all modulation routings assigned to this target.

   • Sample Start or End: Choose None, or Bar, Beat, or Triplet values to rhythmically modulate the sample start or end position.

   • Loop Start or End: Choose None, or Bar, Beat, or Triplet values to rhythmically modulate the loop start or end position.

   • Loop Position: Choose None, or Bar, Beat, or Triplet values to rhythmically modulate the loop position.

3. Set the amount of modulation with the Amount slider.

4. As an optional second modulation routing, set up your keyboard modulation wheel (Mod Wheel) as the source, and Loop Start as the target.
