Parameters

This tutorial explains how parameters work on MAINFRAME-B and how they let you translate MIDI data into real-time lighting behavior. Parameters are the primary way you shape the visual response of the system, both manually and through MIDI control.

What parameters do:

• Parameters define how MAINFRAME-B interprets MIDI input as light
• There are 10 parameters per zone, each affecting different aspects of behavior
• Parameters can be controlled using the onboard encoder or MIDI CC messages
• Each parameter has a value range from 0 to 127

Types of parameters:

• Display parameters (color, brightness)
• Animation parameters (speed, decay, position)
• Modulated parameters (can vary per note based on pitch, velocity, or randomness)
• Non-modulated parameters (set values for a zone)
• Input modulation ranges (limit pitch and velocity input for modulation)
• Output ranges (assign portions of the LED strip to a specific zone)

How to control parameters:

• Rotate the encoder to scroll through available parameters
• Press the encoder to enter edit mode for a selected parameter
• Adjust the value by rotating the encoder while in edit mode
• Press Function while turning the encoder to adjust secondary values, such as modulation range or cutoff thresholds

Using MIDI CC to control parameters:

• Each parameter is assigned a specific CC number
• Sending a MIDI CC value from your DAW or controller will override the manual setting
• A blue LED on the parameter indicates that the last value came from MIDI CC

Per-zone control:

• Each zone maintains its own independent set of parameter values
• Switching zones allows you to edit and store distinct lighting behaviors per MIDI source

Parameters are at the core of MAINFRAME-B’s expressive power. Whether you’re shaping a live visual performance or refining a look in the studio, parameters let you directly control how light reacts to and expresses your music.
