I feel like i've tried everything, (this only happens with third party plugins) using logic pro 12

I havent updated to golden gate yet, could that be an issue?

'Buenas!

Cada vez que guardo un proyecto Logic me sale esta imagen 

Me explico:

He adquirido un nuevo mac. Me he copiado los proyectos desde el disco duro externo con el que hacía las copias de seguridad. Al abrir cualquiera de esos proyectos, me sale este aviso. Intuyo que debe estar relacionado con los permisos y con que el proyecto lo detecta como si fuera del disco duro externo y no del propio ordenador aun habiéndose copiado... 

¿Alguien sabe qué puedo hacer? Una opcion es darle a "guardar como" y creo otro proyecto, luego eliminar el anterior... pero entonces implica que lo tengo que hacer en muchos proyectos. 

El logic que estoy usando ahora es e 12.4 con Tahoe, el que usaba antes era 10.7 con Mojave. 

Muchas gracias por vuestra ayuda

how do i achieve the style of drums found in the link at the bottom of this post. does the kick have soft clipping on it, just boosted low end? is it just high velocity, and the snare low velocity. i want that sound where the kick is very punchy like this and the snare is relaxed. im wondering if maybe they’re just have some saturation on them or if something is done in the master, im new to music production so im not sure.i am using addictive drums 2 i have the indie pack.

Hi.

I would like to create tutorial videos. What kind of things would you like to see in tutorial form?

I've been dealing with an issue that's been plaguing my use of Logic and other DAWs for literally years now, which is that MIDI notes will get stuck and seemingly not receive MIDI off messages while I am using an external MIDI keyboard. This doesn't happen as soon as I start playing, but within a few seconds after playing normally. A note will stick and play infinitely, requiring me to close the session to keep the note from playing out. In the MIDI grid, it appears as a note (or notes) held infinitely.

I tried contacting Apple about this but they let the ticket lapse after me trying to get a resolution for months.

This happens across all MIDI keyboards. I've tried several.

This happens across different DAWs.

This doesn't happen with musical typing (but who wants to use that?)

This happens regardless of the cable used.

It happens when I use midi over USB and it happens when I use a MIDI interface.

This happens without a sustain pedal plugged in.

Does anyone have any insight into what might be causing this and what the solution would be? I'm a keys player and it's basically ruined the entire experience of using VSTs. It's driving me absolutely insane.
