logic 16
Version 1.1.9
Increased Logic16 USB bandwidth performance by 50%! Old limits were 2 ch @ 100MHz, 4 ch @ 50MHz, 8 ch at 25MHz, and 16 ch at 12.5Mhz. New limits are 3 ch @ 100MHz, 6 ch @ 50MHz, 9 ch @ 32MHz, and 16 ch @ 16MHz.
this seems unbeatable value for money IMHO looks like I wll have a nw toy next week ]
