I'm not really sure that I understand you, but … I assume you are trying to use the Orville as a MIDI controller.
Using MIDICOUT, if mode is set to double, and number is less than 32, it will send both the LSB and the MSB as separate controller messages.
I assume that the delay you are controlling is on some other piece of equiment, it this case it will determine what the interface shows – Orville has no control over that.
Don't know what your 'midi solutions' router is. But, Orville does not send sysex messages for other units – these are normally proprietary and Orville does not know what they are.
