That's good to hear. Do you know what the problem was that you were having? As Duncan21 mentioned, H9 Control does work fine on Windows 7, although every now and then we do hear from people whose H9 doesn't appear as a MIDI device on Windows… This is the first time though we've heard of a problem like the one you described. Do you know what it was?
