Synth zone filter envelope question


The Halion 6 manual states, that the “The Amp, Filter, and Pitch envelopes are pre-assigned
to the amplitude, the filter cutofffrequency, and the pitch of the zone” (page 112).

But the filter envelope only has an effect, if I assign it to the cutoff parameter in the modulation matrix.

So what does “pre-assigned” mean? Am I missing some option to activate the envelope without assigning it in the matrix?

Thank you very much

Change the Env Amnt to activate the filter envelope.
