MIDI enveloppe automation bug

in session view: create a midi track, and double click to create a clip.
draw any enveloppe parameter (say master volume).
you'll see the orange dot move according to the enveloppe you created.
now delete the clip. the orange dot stays on its last value, and it's impossible to get rid of the automation you have created.

deleting an enveloppe automation clip should erase all the automation contained in it, shouldn't it?


i hope i make myself clear, if not please let me know.
cheers.

this one hasn't been solved.
if you create an automation in a clip envelope and delete the clip while it's playing (session view), the last automation value is still active (you can see the orange dot staying at the last value).

it sucks because the only way to get rid of this automation is to create another clip, set the automation to nil and play it.

Yes, I noticed this one when we were beta testing but it undersandably got overshadowed by some more important bugs. The automation still hangs around when deleted, causing your controllers to be restricted until, as you say, you create another clip and hit record again. It could be very annoying in a live situation.

Sorry for the long delay in answering this.

We don't consider this to be a bug. When a clip stops, the current clip envelope values stay at their values until the next clip starts. It doesn't matter whether the clip stops because you stop it (or it stops itself because it's a one-shot), or because you delete it.

As long as no clip is playing, it doesn't matter much where the orange dots are. As soon as a new clip is fired, that clip's envelopes will take effect, so all is well.

And you can easily image situations where the current behavior is definitely the one you want: suppose you create a clip envelope for the track's volume, to lower it by 12dB. If you stop the clip (or delete it), you don't want the volume to jump up to 0 immediately, because that would affect any reverb or delay tails.
