Build the NMF Model working ?

Hi,

Thanks for preparing and posting the Hans Tutschku composer's Examples.

I managed to build a database but couldn't  Build the NMF Model part.
The analysis is stuck and Max console printed this : counter: doesn't understand "buffer". Any hint ? 

OS 10.14
Max 8.3.1
Flucoma 1.0.4
Bach 0.8.1
Cage 0.6.0

Best,

N.
