Hi, Today, I plug my LTC module to the core to have the 2 In/Out leds and , eventually, the midi thru port. Before I plug the LTC module, everything works great, once it i splugged, evertime I'lm sending data, both in/out led are flashing at the same time but, waht surprinsing me is that displaying data or even sending data becomes very slow :( What can I do ??? Any idea ??? Heeeeellppppp !!! :-[ Julien
