Hello Danmusic1968,
Sorry you are having trouble with H90 Control. Are you able to check if the H90 shows up in the Device manager?
Make sure you are not using any application that may divert the H90 as a MIDI device. This is typical of DAWs. Does this happen with all other applications closed?
Make sure you’re connecting directly to the computer, not via any USB hubs. Use the USB cable that came with the H90.
