You can lock a module by right-clicking the module label and choosing Lock Module in the context menu (see the Oscillator Menu above). This causes the parameters (settings) of the oscillator module to remain unchanged (locked) as you change presets.

For example, if you lock OSC A, the module remains the same even when you load a preset (that would normally change the oscillator module).

After locking a module, you can unlock individual controls (such as the WT POS knob, for example), as needed.

Note: This does not apply when you initialize the entire preset (by choosing Init Preset using the main menu). This initializes all settings and removes any module locks that you might have set.
