Is there a way that I can control the volume of the XS rack from an external synth?  (without having to turn ANY knobs on the Rack...)

I know how to assign it when the Rack is in multi mode…

But as far as voice/single mode this is what I’ve found out:

I know that the CC message used to control volume is 07.  So I assign that CC message to one of the sliders on my controller keyboard (Fantom G).  Ok it works...but it also manipulates the volume of my Fantom as well.... 

I don’t want it to do that.  I only want it to control the control the volume of the XS rack…

What to do… what to do....

please?  I’m kinda finding it out on my own… but it would be great to have someone at least kinda guide me a little on it.  Just need a little direction, as least a start… Your assistance will help fill in a few of the gaps in my understanding of this concept. 

Thanks in advance,

Usually kbd workstation can’t control any program change include the volume also...so my advice just buy a kbd controller(small one/rack vers like novation Zero SL) and you will get all you need to control Motif XS rack.hope it help...:)

cheers

Perhaps this will help you understand what is going on.

CC messages are Control Change messages, this is a type of message that is always MIDI Channel specific. In other words, if you are sending cc007 from your controller, every device that is connected to that controller and is receiving on the MIDI channel you are sending that Control Number will respond to the message. cc007 is MAIN CHANNEL VOLUME… if you are sending that message on MIDI channel 1, then all devices on MIDI channel 1 will have to respond. They have no choice.

If you would like to have one product respond and not another, you either have to:
FILTER or prevent it from going to one of the devices.
You can tell the device to ignore volume messages
You can set the device to its own MIDI channel.

If your controller has ZONES, each ZONE can be set to address external modules on a different MIDI channel. This way when you sent cc007 on MIDI Channel 1 it would not affect any devices set to MIDI channel 2-16.

Hope that helps.

thanks mister.  My controller is the Fantom G.  (Not sure how familiar you are with it...), but the Fantom G has an feature that allows it to directly (seamlessly) integrate external synths into its live mode (same thing as multi) and single mode (same thing as voice mode) So I’m thinking that it’s “external” channel 1 doesn’t have any connection with its internal channel 1.  So i guess now I know why.

Someone else also suggested that I use the midi filter to stop that channel from accepting midi messages, but when I tell the filter to stop volume communication on channel 1 (so it won’t affect the internal sound), it also stops it from sending it to the other devices that are communicating on channel 1.

But I do believe that you suggestion about telling my Fantom G to ignore volume message though may work.  But I am afraid that these instructions are ALL done through the midi filter page and they are channel specific… so I’ll be right back where I was. 

Also since cc007 is main channel volume, what is the cc message for master volume. (because when I’m in multi mode, this would allow me to decrease or increase the volume of the entire multi (entire rack) instead of ONLY the sound/patch that is on that midi channel/part.

So. Mister, is there a way to control Master Volume via midi (volume of the entire synth?)

Yes, MIDI provides for a Universal Master Volume message:

F0 7F 7F 04 01 00 dd F7

where “dd” is the volume 0~127 (00~7F in hex)
