Been using the e-mu 1820m for 5 years. Currently am attempting to use it with w8-64. Sonar 8.5.3, and X2, result in system hangs. Today Reaper did this. Driver verifier blames the ctoss2k.sys file as the culprit. Just installed the beta august 12 driver for testing. This changed the ctoss2k.sys driver. At least the internal last modified date. Will the KX drivers/mixer work with this E-MU interface? Are 8 channels of ADAT supported? MIDI port? I assume the E-MU drivers and Patchmix need to be uninstalled, not just disabled. Correct? Anybody? Anybody? Beuller? Beuller? Beuller?
