As far as I know, the Lab Streaming Layer (LSL) is only available for the “Performance” Tier of the License.

“but I haven’t received a response from Emotiv support yet”
I haven’t had a response lately either. But maybe they are very busy lately? I don’t know.
So I guess we’ll just have to keep waiting for someone from support to respond, or wait for some customer/user who’s just browsing this forum to see this post.
