I read a lot of these threads with questions so I can learn. Can I ask what you're actually trying to do, in the real world? Like, what are you trying to make happen while you're playing a song? I'm asking because I'm trying to follow this action you're wanting to do, but isn't possible, but I don't understand what the benefit would be in an actual gigging (or recording) situation. Sometimes people ask about doing a certain action, that's not possible, but there are other ways of easily making what it is they really want to accomplish, happen. But it might be a tiny bit less convenient for them.
Sure, I'll try, but you might wish to read the previous posts leading up to my thanking
@unix-guy and
@Rex for answering my question, once I'd provided the correct information.
I've spent limited time with my FM9 and have built a kind of kitchen-sink utility preset as my MAIN RIG, which consists of CLEAN, CRUNCH, and LEAD scenes.
While setting up my scenes I though it might be possible to include a wah and formant (per LT's Wah Tips & Tricks video) for one of the 3 scenes, the CRUNCH scene.
However, even though it is possible to place the wah block on 3 separate channels for each the 3 respective scenes, it is not possible to allow the wah block's "control" modifier (located in the wah block's controls main screen) to be placed on each channel within the modifier window. You need to select either ALL channels, or one channel. It is not possible to switch control modifier channels within the modifier window and have the wah sound across the 3 scenes on separate individual wah control channels (Must be either ALL, or Ch A, or Ch B, or Ch C, or Ch D). The and/or possibility doesn't jive at all.
My hope was to be able to do this, so the wah and formant could be set on each control modifier channel to be active, or bypassed for individual channels. The goal was to allow scene CRUNCH to enjoy an active wah and formant, while scenes CLEAN & LEAD, the wah/formant would be bypassed.
Unfortunately, what is described above is not possible with the control channel modifier, so I've accepted the fact that if wah and formant is to be used, it must be active at all times across the 3 scenes and bypassed when the EV-1 is set heel down.
This essentially provides (here's a good way of viewing things) wah and formant for all 3 scenes, whenever the mood strikes. I just need to remember that if the pedal is engaged, even slightly, I'll hear it. I might consider tightening the treadle's sweep so the pedal doesn't inadvertently loosen up over time and interfere with normal play.
Hope this answers your question regards real-world gigging scenarios. A friend of mine recently informed me that my usual open-mic venue has re-opened its doors now that they have enough waitstaff and workers to cover the venue's evening hours, which includes our local region's longest-running open-mic again. Looking forward to putting the chops in proper order and making it to my local open-mic soon.
