Decay time of the Convolution Reverb

[Steve Mohican]

Is it possible to modulate decay time of the Convolution Reverb Unit?
When I try to turn decay time, the transition is muted and not smooth.

[Christoph Hart]

Nope, impossible. You need to recalculate the impulse response and feed the new impulse to the engine, that's why it's muted.

@Christoph-Hart Ok I understand.
I see decay parameters on some convolution plugins. Maybe they are using multiple convolutions and switch between them? Could we implement it with this way or mabe reverb time can be adjusted or any alternative ideas?

Using parellel multiple convolution reverbs can cause tremendous cpu usage, especially if the IR sample is long. I don't think this examples are working like that.

It's not possible for now. Maybe with forthcoming SNEX engine, but I'm not sure.
