Controlling FX from Modulation Matrix?

I am trying to figure out a way to modulate the cutoff of a MorphFilter from within a modulation matrix.

I’m trying to create some dubby techno chords and I want to modulate the echo’s cutoff gradually after a note is played. It seems like the only way to accomplish this is by automating quick controls from within Cubase, but I’d prefer to have it handled all from within H4 if possible.

Thanks. :]

Okay, I’ll go ahead and assume since nobody replied that this isn’t possible.

If anyone from the Steinberg dev team sees this, please consider such functionality in the next update/version of Halion. It’s nice to use the mod matrix to control the parameters of the selected layer, but it would give a lot more flexibility for sound design if you could modulate the FX params.
