Click a button to change the value of the (6th) byte of a bunch of sysex parameter-change messages at once?

Question

MIDI Target Manufacturer(s): Korg

QUESTION: Is there any way in MidiDesigner that I can programmatically tweak the 6th byte of my sysex message based on what button I mash in MidiDesigner? 

With the Korg M1, changing modes changes the affected 'page' (6th byte) of a sysex message. I currently have a button in my MidiDesigner template that selects SINGLE or DOUBLE OSC mode and I'd like that to trigger the loading of a different matrix of sysex values for all parameters - specifically just for the 6th byte. In this case, I want to adjust parameters for sound design.

The 6th byte (green) must be changed to affect the same respective parameter depending on the mode of the synth:

F0 42 30 19 41 05 0A vv vv F7 will set the VDF1 CUTOFF parameter for OSC 2 (DOUBLE OSC MODE)

F0 42 30 19 41 03 0A vv vv F7 will set the VDF1 CUTOFF parameter for OSC 1 (SINGLE OSC MODE)

Attached photo is a page I made that appends the 6th byte values for SGL (Single) and DBL (Double) OSC mode.

Can this happen in MidiDesigner or is that beyond the scope of the app?

Very short answer: You can tweak two values of a sysex: the V and the L (channel). For L you need a Channel Changer. Then you can move the channel changer using supercontrols with MAX values that align to the proportion of the max you want the channel changer to spin (or a regular supercontrol, which would change the V). Anyway, let's see if that (plus google) gets you started.

In the future we'll add a third and perhaps a whole bunch more variables, but for now, you've got L and V that you can change. Since it seems your V is busy, you've got one variable. Hopefully that's enough for this case.

Thanks for checking out MD!

Channel Changer will let you go the full byte range (7-bits, 0-127) so it's not as bad as it sounds.

Did this answer work for you, fail for you, do you need more information or more help? Thank you.

Yes, this should give me a foundation to work out the rest. Thank you all for such quick help.

I am able to apply L to my sysex messages now, but I can't figure how make those changes hold across to multiple parameters. I tried the A-B function but seems I can only do 1 A-B per knob pair.

I need to map 4 different L values to about 140 respective parameters.
You can see the SGL and DBL column have differences of 1,2,6, and 9 (02-01=1, ... 0A-13=9). Then, there are between two and eight 'positions' within each page (which map to the physical buttons on the synth).

I attached a picture to show the concept I'm trying to achieve. I'm trying to create an easy M1 editor in MidiDesigner but the synth is proving itself quite the bear to tame.
