This is the situation. I have a Synth in a patch that is turned on and off by a preset manager. When the peset manger turns off the patch the tail of a synth or a reverb is cut abruptly. I would like to find a way to preserve that tail until it dissapears and then turn off the patch that contains the synth/reverb. The idea of turning off the patch is to reduce CPU usage since it is not being used.

You should use 2 items of the same patch (or duplicate the rack).
Another way is possible - but only for reverb - you do not use the reverb from your synth, and you send the synth audio output in another reverb plugin.

Hi. thanks for your reply. For the reverb is like using a reverb bus and send the dry signal to it. But wat about the the tail of a long release synth? I was thinking on using a milisecond counter that could turn the patch off after the tail fades and disappears completely. Could you please be more explanatory about "You should use 2 items of the same patch (or duplicate the rack)."?

Any other ideas are welcome

Hello Arialjazz .
May be you can use this strategy

The joffo78's example is nice.
I was thinking about someting easier. You have the same plugin on 2 different racks, with different presets. When you turn on the second rack/preset, the first one is still playing with its reverb tail. You can had another patch to stop midi in when the pther rack is playing.

Did you try with a long fade between presets ?

Hi cmodica. What do you mean by long fade between presets? Could you be more explanatory please?

Thanks for this, joffo.

The env follower solution seems ideal to me. Probably takes more CPU, so I'll have to wait for my new computer to implement it. But it will hopefully solve the problem of not hearing tails when disabling a patch (and then hearing them when I re-enable it!)

Oh wow, looking further, it automatically disables any time the level reaches zero, and then re-enables the next time it sees MIDI? Excellent!!! Well done!

What do you mean by long fade between presets? Could you be more explanatory please?

If you right click on the preset module, you can see the "global fade duration".
If you right click on a preset in the list of preset, you can see the "fade duration" for each preset
So, you can for exemple fade from wet to dry in a long time and it didn't cut the tail of the sound abruptly.
Or you can disable the "Audio In" in the second preset and let the the reverb tail die.

I hope it helps, but it is possible that i didn't understand your problem.
