Structure Full: Modulation matrix modifiers question

[systemexclusive]

Who knows meaning of "part modulation matrix modifiers"? There is nothing about it in document "Structure Plugin Guide" on page 53!
Such modifiers as "Vel", "Sustain", "Amp Env" are self-explanatory, but not clear how modifiers like "Clip -", "Switch", "Lag", "Drift" and so on affect the source.

I want to find simple INVERT modifier. Need to slightly "pitch down" sample on lower MIDI note velocities.

@Digi: Please update documentation for "Structure Sampler Player". The same chapter in documentation for the LinPlug Albino RTAS instrument contain FULL list of modulation matrix modifiers with description and hints how it can be used in real world application.
