Ken wondered, "The Logic Dongle blocks communication to this MIDI interface. Is there any way around this? Anyone out there using this with Logic on the PC?" Mine works fine, but I have the Doggle on COM1 and the Opcode unit on COM2. If your system profile does not show a COM2, go into "Setup" mode as your machine boots and look for a way to turn it on. (First, of course, ensure that you have an extra serial port on the back of your machine.) Best/Enjoy, Tim
