Very impressed with my new TT120 Valenta HST sounds ! Not sure if this has been thought about but what about a "Nature" profile, so that one perhaps could buy a card with a speaker, wire it up and put it in a house, shed, bush etc with birdsong, cows, sheep, farm machinery, dogs, perhaps odd things such as couples having a row etc.. would work with any scale. Apologies if such a thing already exists and I have missed it !
