Summary0001075: Element Plugin loads everytime playback is started.

I've talked to the developer of Element and this is what he observed:

"Basically what's happening is OpenMP stops its entire audio engine (closes the audio device) when stop is pressed. Because of this Element (and every other plugin) gets fully deactivated. Then, when you press play, the audio device is opened and all the plugins are activated again."

I've checked all the audio devices I have listed, but none allow the audio device to stay on when playback is stopped.

Every time I hit play, it decides to load all the instruments and effects within Element (up to 20 second loading every time I hit play).

The developer of Element is interested in what you have to say.

Thanks for reading!

The developer was sure this was an OpenMPT specific issue... Turns out Reaper is having the same problems! Sorry about the false alarm guys!

A VST host is allowed to stop and resume playback of VST plugins at any time it wishes. If the plugin developer decides to reload its settings when playback is resumed, that's a fault of the plugin. I'll try to get in touch with the developer.

This is solved now.

Developer describing the problem:
"So basically Element, in the plugin version, caches the number of ins/out busses so that it doesn't reload itself all of the time (yeah... I know). Turns out, some of these hosts do things slightly different when stop/play happens and those io counts were not cached"
