Oh, I forgot to mention that another approach (as opposed to stack/mute/remap) to getting individual samples out of the locked Acoustic Agent kits is to resample to an audio track, then you’d have raw samples to work with in your own custom ‘beat agent’ kits.
Example: Say you want to make samples from an Acoustic Agent kit’s kick drum.
Set up the kick drum so it sounds exactly like you want for some samples.
Make a track (instrument or MIDI) that’ll play the kick drum at different velocities with plenty of space between each hit.
Instant Render the track into an audio track.
Now you can cut that audio track up and use it in your own custom beat agent kits.
Thanks for the suggestion regarding rendering Acoustic Agent parts and then cutting out individual drum hits to use as samples in Beat Agent kits.
I have quite a few excellent sounding older acoustic drum libraries that allow me to access the individual samples. (Which is unusual in this day.) So I think I’m covered in that regard. 
My bladder is a good teacher.
Awesome, and GA does come with a lot of nice unlocked layers to use as well. Every once in a while you might find something in one of those ‘locked’ Acoustic Agent kits ya want to sample and do more with…
I was checking out Wave Alchemy’s sample-based “Triaz” drum plugin as something to use in conjunction with Groove Agent 5 and I didn’t even remember that I had purchased the company’s “Syncussion Drums” and “Complete Drums Bundle” drum sample sets.!
I’m such a dope. That’s how many plugins and sample libraries I own. I can’t even keep track of them all! In my defense, I just never got a around to re-downloading these libraries when I finally upgraded to an Apple Silicon M1 Max MacBook Pro.
The “Complete Drums Bundle” includes thousands of samples that I can use to build my own fairly elaborate kits in Groove Agent. So that’s cool.
