The Matrix display provides a visual overview of the current pattern in Boom’s sequencer, and is a quick way to keep track of the pattern’s rhythm and velocity, as well as what step Boom is playing at any given time.
Each horizontal row corresponds with one of Boom’s 10 instrument channels, and each vertical column represents one of the 16 rhythmic steps that make up a pattern.
When an LED in the grid is dark, no note is sequenced to play the indicated instrument on that step.
When an LED in the grid is lit red, the corresponding instrument is sequenced to play at that step. The brighter the LED is lit, the higher that step’s velocity has been set.
You can click each LED directly to add or remove a note on that step. When a dark LED is first clicked, that step is set to play at high velocity. Clicking it a 2nd or 3rd time will cycle that step through two levels of lowered velocity, reducing that step’s volume. Clicking the LED again will silence that step, and turn off its light. Right-clicking an LED will toggle its on-off state, preserving the current velocity setting.
The Pattern display above the Matrix shows which of the 16 patterns in the current preset is being shown in the Matrix display.
The Copy and
Clear buttons above the Matrix are used to copy or erase patterns when in Pattern Select mode.
