Shut Off Subcontrols?

Question

I have a supercontrol that spins 2 controls (or 5, or 10, or x controls). I want to create pushbuttons to control which of these is on.

Answer 1

While there is no MIDI Designer feature to shut off subcontrols in performance mode, you can usually achieve the same thing using Channel Changers. By changing the channel of the subcontrol to something that your MIDI target is not expecting, the control is essentially off.

Setup

One supercontrol with two subcontrols.

Setup for Sub 1

Instructions In Detail

1. Set up is a knob that controls two other knobs: Sub 1 and Sub 2
2. Add a knob and call this knob "Hidden"
3. Change its type/subtype to Channel Changer. Accept the defaults for Channel Changer conversion.
4. Set "Hidden" knob to "Hide in Performance" (in advanced)
5. Add Sub 1 as a subcontrol to "Hidden"
6. Create a toggle button called "Off"
7. Make it a supercontrol of the "Hidden" ocntrol

Switch to performance mode. The "Off" button will change the channel to "16" for your control. 

I Don't Use Channel 1!

Set the MIDI minimum on the Channel Changer Super ("Hidden") to be the channel number you need (it's 0-based, so Channel 4 would actually be called 3).

Dan, this is great.  Personally, I would really like to be able to use the accelerometer to adjust different parameters in a single iPad synth.  On the iPad, it really only works when all the parameters are mapped as different CCs on a single MIDI channel.  So the above solution won't work (as each parameter is on a different channel).  

I am putting together a layout that has 4 layers of sub-controls and uses MIDI Designer Lite as a MIDI pass-thru just to be able to do what I want.  Basically, it sends a channel changing CC out to six knobs in MDLite and back to MDPro on separate knobs on channels 1-6.  Those knobs have subcontrols that are all on channel 1, which will go to my synth on channel 1.  

Good news, it works! But I'm afraid it will end up clogging up the iPad's virtual MIDI and slow down or crash when I already have multiple audio and MIDI tasks running on the iPad.  

So my request:  
Is there a way to set a channel changing knob so that it sends its commands within MIDI Designer, to another knob?  If so, I can't find it.   If not, please add this option.
