Yes, focusrite support was not able to resolve problems with this unit. I think they discontinued it because of FW problems. I am using LM on every project, but I need to do special procedure before I can start to hear something going through LM. After loading project in Sonar, I need to unplug and plug FW cable into LM. After this reset everything working right. I am using mainly Pultecs, SSL {without hipass}, API2500 and Distressor {really great sounding!}. LM is great unit with great potential with bad driver programming.
