Hello Omari

That's sad that mail was delivered with such delay :( Probably it's
important to be subscribed to the list before posting there.

For sure such work is very interesting. Do you have any news now? Did
you succeed to implement TRM-based synthesis? Friday is already gone,
probably you have some interesting results or even some code to share.
