Enclosure - AmpMinLevel=0

[ahall41]

If you set AmpMinLevel=0, and then completely close the enclosure, nothing will sound on re-opening until another note is played. These enclosures are usually used to regulate the sound balance between near and far perspectives, and is only a problem if you want to change the balance in real time using a midi controller. The work round is to code AmMinLevel=1, but at this setting some sound will bleed through. I don't think this is a high priority, but thought the phenomenon should be recorded (I recently forgot to code 1 and set it to 0 and someone complained about it!)

I'm not convinced as if you set AmpMinLevel to 0, some sound still bleeds through - which may or may not be desirable. Perhaps the spec should be changed, so that 0 generates a warning? And add a 'health warning' to the Help too? Or, if 0 sets the pipe to 'off' then perhaps it could be some ridiculously low value that is inaudible?

I think AmpMinLevel=0 ahould be considered as a valid value and the current GrandOrgue behavior as an incorrect.

It is a valid value, and it mutes the sound - as it forces an amplitude of zero on any attack sample - which also incidentally cancels any existing attack sample and returns the sampler to the pool because that's how the audio engine fader works.

I'm going to change the audio engine behavior.

Ok, but it will require quite a lot of care.
