MatrixBrute has 3 memories available when working with a preset: The active preset (i.e., the edit buffer) The physical panel settings The Compare mode memoryCompare mode allows you to view the stored presets while editing the current preset. This is useful in two ways: To compare the edited state of the preset to the unedited (stored) version, or to any other preset To preview another preset location before overwriting it with an edited preset.To enable Compare mode, hold the large Preset button and press a matrix button to select a preset. The front panel behaves differently in Compare mode:The Preset button blinks and the SEQ / MOD buttons are darkThe Sequencer screen displays COMPThe Preset screen displays the number of the previewed presetSelect a different preset to preview by pressing its matrix buttonThe blue, flashing matrix button indicates which preset is being previewedYou can make temporary changes to the previewed preset, but they cant be saved......because the Save button will only save the preset that was edited before entering Compare mode.Press Panel or Preset to exit Compare mode. This reloads the previous state of the preset, including any edits that had been made before entering Compare mode
