Performance Pads
The Reloop Mixon 8 Pro comes with 8 performance pads, that can be used across 9 different performance pad modes
The modes consist of:
Hot Cue Mode: When pressing pads 1-8, you can add up to 8 Cue Points. Holding SHIFT and pressing buttons 1-8 will delete the Cue Points. Press the Hot Cue mode button twice to enable Cue Loop mode. Pressing pads 1-8 will play a Loop Roll from the Cue point position.
Loop Roll Mode: When pressing pads 1-8, you can activate a loop roll. The loop length is determined by the Auto Loop Range currently selected in the Loop section of the software, which you can change using the PARAMETER + and - buttons. Press the Roll mode button twice to enable Saved Loops mode. Pads 1-8 will trigger saved loops.
Sampler Mode: Pads 1-8 trigger samples loaded in your Sample Banks. Use the PARAMETER1 Left/Right buttons to cycle through Sample Banks. Press the Sampler mode button twice to enable Pitch Play mode. Press and hold the performance pad for 3 seconds to access Sampler Velocity mode. When enabled, the Sampler sample slot volume will now be velocity-sensitive when played using the performance pads.
Slicer Mode: A specified range (or domain) is divided into eight equal sections, and these eight sliced sections are assigned to the respective performance pads. Pressing SLICER once activates the shifting Slicer Domain mode. Pressing SLICER twice activates the fixed Slicer Domain or “loop” mode. Use PARAMETER1 to set the quantization for the slicer function. The quantization can be set in four ways: 1/8, 1/4, 1/2, and 1. Hold SHIFT and press PARAMETER1 to set the domain. The domain can be set to one of six settings: 2 beats, 4 beats, 8 beats, 16 beats, 32 beats, or 64 beats.
