I have a DR880.. DR can be configured to respond to receive / transmit midi via USB or the two midi port.. For the DR USB, you need to install the driver. Using midi port, you don't have to install any driver.
The choice depends
- if you have limited midi out port , you may want to use DR USB. Provided you have enough USB port.
- if you have enough midi out port , use DR MIDI port, and you don't have to install any driver.
- Check DR manual where to setup this, it can only be set to function either USB midi or via regular midi port.
If you are recording DR output as midi data, then MIDI out cable is required (from DR midi out)..
If you are recording DR audio, then only one midi MIDI cable (from Focusrite midi out to DR midi in) is required.
Once you have setup all the above.. Press "p" in Sonar (preference) and check MID Devices, make sure the port you use is being checked.
