Presets have parentheses with (i) (at) what do they mean?

[backagain]

Some Synthmaster presets have lettering in parentheses after the name:

(at) - probably means channel aftertouch or is it full polyphonic aftertouch?
(mw) - Mod wheel
(i) - I have no idea

Please describe every one of them. I could not find it in the documentation (2.8.4)

Thanks.

(i) refers to the sound designer Isigna. Many of the other sound designers have their initials but no parentheses. I have not seen the options you describe. What sound bank are they from?
