First, have all 3 units powered off. Next, hold down the button directly underneath the 4th rotary encoder while powering it on. Keep holding that button until NCSo flashes on the screen and it will go to EG. You can let go of the button when EG appears on the screen. Then press the Exit button, and NCSo should appear on the screen again. Repeat this process for each unit.
Next, open Sonar then go to Options> MIDI devices (SonarX1 Edit> Preferences> MIDI> Devices). You should have BCF2000 port 1, 2, and 3. You should also have 2-BCF2000 port 1, 2, and 3. If you have additional units, they will show up as 3-BCF2000 port 1, 2, and 3 respectively. In the input and output sections, check BCF2000 port 1, 2-BCF2000 port 1, and 3-BCF2000 port 1. You can leave ports 2 and 3 unchecked. Press OK, then go to Options> Controllers/Surfaces (Sonar X1 Edit> Preferences> MIDI> Control Surfaces).
If you have any devices in the Controllers/Surfaces window, delete all of them so we can start fresh. Add a Mackie control with its input and output port set to BCF2000 port 1. Press OK. Add another Mackie Control (not the Mackie control XT), and set its inputs and outputs to 2-BCF2000 port 1. If you have an additional controller, add a third Mackie Control and set its inputs and outputs to 3-BCF2000 port 1. Then you can close the Controller/Surfaces window.
Create a session in Sonar that only has 9 tracks. Notice that each one of the BCF2000′s has an illuminated button on Channel 1. This is light to look at in the next step.
Go to Tools> Mackie Control – 2 (Sonar X1 its located in the Utilities menu), then press the configure layout button. On your second BCF2000, very very slowly turn the first rotary encoder until that light on the second unit goes out. You will only turn the knob about an 1/8th of an inch before the light goes out, so just be sure to turn it slowly. When the light goes out, click the button in Sonar that says “press again when done”. You should notice on the first BCF2000 that ALL faders are in the up position, and the second BCF2000 only the first fader is in the up position. Close the configuration window.
Add an additional 8 tracks to Sonar, bringing your track count up to 17.
Go to Tools> Mackie Control – 3 (Sonar X1 located in the Utilities menu), then press the configure layout button. On your third BCF2000, very very slowly turn the first rotary encoder until that light on the second unit goes out, only turn it only a little further than you turned it on the second unit. Click the button in Sonar that says “press again when done” to see if the 3rd unit’s first fader is in the up position. If it isn’t, click on the configure layout button and try again. It will take a few tries with the 3rd unit to get it to work. When thats done, everything should be set up and working correctly.
