CME VX5 MIDI Controller

How do you have the MIDI thru and "Send Value to" parameters set in the Hardware inspector for each slider (fader)

MainStage doen't know this keyboard and therefore doesn't know about the motor faders. Without that MainStage doesn't actively send MIDI to the keyboard. There are two ways for MainStage to support more complex devices:

(a) via the already mentioned option. Go to "Layout" mode, select a knob, "Learn" the assignment and select the "Send Value to" after learning. Then go to "Edit" mode and move the fader in the workspace with the mouse: does the fader on the VX5 work? Then you are done.

(b) via a special device adaption. This is necessary if the device requires special MIDI messages to control it's status e.g. to update displays, etc. In that case you probably have to contact CME and ask them about device support for MainStage.

Step 1 --- Install the MIDI Monitor tool from snoize.com and check that when you move the faders on your CME that MIDI events are actually being transmitted to your macintosh.

Step 2 --- Use Logic (or another DAW) to record slider movement, then play back the sequence and see if the sliders move.

Report back!

For each of the sliders that you created in Layout Mode, what are the settings for MIDI thru and "Send value to" parameters?

Have you assigned the slider controls so that they are associated with the appropriate MIDI CC number for the sliders on the CME?

I.e., click on each slider in edit mode, then in the third tab (which will probably be initially named "Unmapped", select the appropriate device (the channel strip tied to the external MIDI device) and select the appropriate value (probably a MIDI Controller with the desired CC number) on the right.

There's a few modes for this.. and you can change it globally for everything or each object individually. The thing that you're looking for is the "Respond to hardware move' popup. You can see this in the preferences window, and also in the Attributes tab along the bottom when you select objects in Edit mode.

I prefer Pickup which means that you can move the fader on your hardware and nothing changes until you reached the saved value in the sound. So no sudden jumping because it doesn't respond until you 'grab' it.

The default is Jump which means that the parameter does just that. I guess this is what you're seeing.

The third choice is Relative which keeps the same difference between the incoming midi and the parameter value until it hits max or min when it will flattens out.
