I want to control multiple mixer channels with *one* midi cc

ernest@303.nu · Post by **ernest@303.nu** » Mon May 01, 2006 11:36 am

The subject title says it all...

In fact what I need is a way to control the volume of multiple channels in exactly the same amount at the same time using just one single midi controller, like some kind of 'master volume'

When I try to assign the same midi controller to multiple faders at once, the previous assigned fader looses its cc.

I know I can use multiple single channel faders and assign the same midi controller to them to mimic the behavior I want, but since the application is processing for a multi-amplifier PA system phase-accuracy is a big concern, so I really prefer to use the direct outs of a phase-compensated mixer.

Anyone?

This should be possible with most controllers i think.
I have a Evolution UC-33 which controlls 8 channels volum and pan + effect bus 1 and 2 on this 8 channels with STM16 or whatever.
+ transport for cubase

I should have been more accurate: I want to use just 1 single fader on my midi-controllerbox (thus using 1 midi CC) to move several parameters in one device (mixer) *at once*

Myself & a friend made <a href="http://www.planetz.com/forums/viewtopic ... 0&8">these VST devices</a> which enable you to learn the same midi CC to multiple knobs & send out different midi CC's from each knob. This could work for you quite easily, but you'd have to route your midi through a VST host to use the plug-ins. Something more specific could of course be made in Synthedit.

I do not understand what you want to do exactly but the solution should be to assign the Continuous controller to each of the mixer parameter you want to drive by right-clicking on each of the parameter and assigning the continuous controller number.

I made a quick attempt but then notice you seem not to be allowed to assign a continuous controller to more than one destination parameter in the mixer.

I think what you want is not possible either on the MIDI control surface or on the mixer: one source can deliver one message that should be assigned to an only destination in the mixer.

Still wonder what you would like to do ... could you explain us a bit more ?

You could group faders, if the mixer has that option, or make a patch with one flexor valmonitor feeding all faders on a multival, then linking each of the multival faders to a midi cc# and these in turn to a respective mixer fader. If you don't have Flexor, you could do the same with multiple Valmonitor modules. I posted that module in the devices forum and it's free!

You understood me correctly!

I wanted to assign one single midi CC to multi parameters of a device at once. And I'm a bit surprised that Creamware thinks that should be prohibited.

For this project I use my Scope system as a realtime crossover/processor/EQ/multibanddynamics/limiter for an 8-amps (16 channel) 10kWatt PA system using external D/A convertors.

I want to control the volume of a group of 8 fully processed stereo channels at once as a kind of master volume group. I see no other way of doing this other than having 8 stereo faders move simultanious from one MIDI cc.

Using 8(!) times the Alfonso-device mentioned above would be a workaround if I could set the MIDI channel of a single fader on my controllerbox (as the other faders have other purposes) to another MIDI channel than the other faders but unfortunately I cannot do this.

I hope this all makes sense....

That would be nice

... what CW mixer offers fader grouping?

or make a patch with one flexor valmonitor feeding all faders on a multival, then linking each of the multival faders to a midi cc# and these in turn to a respective mixer fader. If you don't have Flexor, you could do the same with multiple Valmonitor modules. I posted that module in the devices forum and it's free!

Thanks, I will look into that if no fader grouping is possible.

There's a bug in the midi control of the STM2448 channel faders that seems rather irratic. I can get separate midi CCs assigned, but, one minute the STM updates correctly & the next it doesn't. Didn't want to mention it really, but now seems as good a time as any.

Alfonso's MIDI dev. is also an excellant way to put different combinations of drawbars to 1 fader. I use 3 different sliders in drawbar mode on my KS-88, M Audio must have thought that I had hands like Lurch from the Munsters. Drawbars are finger sized, and much closer together than the ones on KS-88. With Alfonso's dev., I can bring in the 4 highest drawbars, while backing down the lower ones on swell pedal, while kicking up the leslie speed. On Santana's Caravanasierra, is where I stole that technique, which was much harder to do on a real B3/C3,i.e.,having to hit the Leslie switch with elbow. I was rather handcuffed then. Who says life doesn't get easier when you get older. BTW thanks again Alfonso for picking out another CWA oversight. CWA should keep making great products, so the guys w/SDK can add to an already great product. Quite a platform, and forum we have here.

To Us, And Those Like Us,

There seems to be a bug in the midi control of the STM2448 no matter what way you tackle it, Scope midi, VST midi or external midi control of the channel faders doesn't work properly from the tests I did last night, but I'll test further today.

With some messing around due to the strange way the STM learns controller assignments, I eventually got it working. I set it up using 8 STM channel sliders, 8 'unoCC' VST devices & a single external Kenton Control Freak slider as master controlling all 8 unoCC's with one controller no'.

I've put a very short flash movie of this in action up on a friend's webspace.

<a href="http://www.si-rus.pwp.blueyonder.co.uk/ ... m">HERE</a>

It's not a particularly efficient method, but it does work. I can't guarantee functionality in a critical sound system (PA) enviroment though.

hi

why not use the fader group option in the sfp mixer? group the faders you want, assign midi only to one of them and all will be moved. or did i miss something?

I've never been able to get the fader grouping to work, so it must be me who's missing something. I assign several faders to a group & select the same group number for A1 on the buss page, but nothing happens. I can assign a midi CC to the A1 group slider, but again nothing happens other than the group slider itself moving. The channel faders don't move at all.

Shroomz~> · Post by **Shroomz~>** » Tue May 02, 2006 4:34 am

Ah got it. The group fader doesn't actually move it's group. I had been trying to assign a midi CC to the A1 group fader instead of one of the grouped faders on the channel page. All working now. It seems to work very well infact.

Wonder what's going on with controller assignments chopping one-another off as you try to learn them to mixer faders tho

Momentary lapse of reason thinking there were actually master group faders on the buss page.

see page 11 of the STM2448 manual for more info.

i agree with atom and another way, (if you don't use mixers with the option of grouping channels) is to use sub mixers.
