Roland does not know anything about Cubasis. They walked me through how the synth should be set up to accept midi signal from a DAW and said once the settings are in place (driver and a “performance” mode turned on) the DAW should see the keyboard - (which it does) and all should be fine. Even after making the necessary changes Cubasis LE still doesn’t work with the synth. Apparently Cubasis is not compatible with the Juno. Thanks for your response.
