Ok then. My fcb is not in stomp mode. I tried that once and didn't really use it much. When I did it was too much like tap dancing and kind of defeated the whole rationale for using midi (in my opinion), so I went back to using the fcb pretty much as it was stock. However, what I didn't count on was this toggling thing that I can now incorporate into my existing patch structure to make simple changes to an existing patch. Previously I have talked about using this functionality for boosting a patch.
The GMajor2 has a preset boost function that I can assign a CC value to, in this case "1". On the fcb for my main rhythm patch I have set up the toggling to send cc1 as 0 and then 127. This means that when I first select the patch, the boost is off. If I press it again, the boost comes on.
In the picture below, you will see that the first cc is value "80". This is the tap tempo on the gmajor. I left it in there but have since realised that it is going to cause chaos. I don't really tap tempo on that patch anyway, so I'll remove that.
TL;DR - It works!!
