I can't get volume on Main Output to work correctly with controllers on my keyboard. It's either all on or all off. Works fine for individual instruments (thought it lumps them all together) but not for main volume output on concert. Thanks for any help.

Hi

The main volume fader is at mapped at Concert Level. Select the Concert at the top of the Patch List, then try mapping a Screen Control to it.

Hi

Your experiences sound like you have a few separate issues? Which version of MS are you using (2.1.3 or 2.2.2?)

As a test, make a new Concert from the Empty Starter template (with no Screen Controls). In Layout mode, make a screen control fader or knob, and Assign it to incoming MIDI from your external controller.

In Edit mode at Concert Level, select that Screen Control, click the Map button in the Inspector and then click the Output Fader in the channel strip area. De-select the Map button. This should work correctly?

Assuming it does, it sounds like you may have multiple mappings for the same screen control in teh other Concert?

Your issue with layered patches would suggest that you have not applied any scaling to the multiple mappings?

Either that or you have incorrectly mapped directly to MIDI CC7 rather than the individual volumes?

I either didn't do the correct mapping sequence before or I'm starting to wonder if it has something to do with my keyboard which has the expression pedal set to the same volume control as the mod wheel.

All this sounds like you are confused about the general nature of MIDI Continuous Controllers (MIDI CC). The MIDI specification allows for 128 different CC's: CC0 to CC127. Some are typically "preallocated" to 'standard functions: CC1= Modulation, CC7=Volume, CC10+Pan, CC11= 'Expression'. Some act as switches such as 'Sustain' CC64.

Everything appears to be scaled from -63 to +64 if that's what you mean by scaling? What do you mean by MIDI CC7?

Mainstage works with MIDI CC's generally in a number of ways:

Some standard ones are automatically passed through to all MIDI/Instrument channels unless you specifically block them. Others are not passed through unless you specifically map them to something.

This mapping can be done basically two ways (with MS 2.2):

a) Make a Screen Control in Layout mode, and assign it to a particular incoming MIDI CC message. Then, you can map this Screeen Control to a variety of parameters such as the volume of a particular channel strip.

b) With MS 2.2, you can do the above Assign and Mapping directly, without the need for Screen Controls as an 'intermediary'.

Yes.

It sounds to me like you have an issue where you have several hardware controls on your Keyboard set up to transmit the same MIDI CC. This is probably not a good idea, and it would be much better if you assigned them to transmit different CC messages (CC1 for Modulation and probably CC11 for the Expression (though you may want to set the pedal to some other number instead.

Once you are transmitting different CC messages, you will be able to Assign and Map much more flexibly:

for example, you could one to control the overall output volume at Concert Level in MS, whilst the other controls the volume of a specific channel within a Patch.

Your issue of layered patches is one of "Scaling": one Screen Control (assigned to an incoming MIDI CC message) needs to alter the ranges of different channel strips to different amounts. You can set this up by using multiple mappings for one Control, each set to work over a particular range (for example a goes from -20 to 0 whilst b goes from -30 to -20 etc.).
