I use Cobalt Digitals, Slow, First Batch I had was Duff, Manufacturing fault but they took them all back, (14 of them) and replaced the whole lot and no problems since.
I can control these from the DCC handset and are easy to program and have inbuilt frog switching also which is great. I use them for the Fiddle yard too.
12 Cobalts are now 360 notes. Big Swallow for sure!
