Anyone using a Boss ES-8 to control their KPA?

Ive been using the Remote but I'm looking for a little extra MIDI capability while using a Line 6 M5 and Eventide H9 in conjunction with the KPA. I have an ES-8 laying around and I'm curious if anyone had used one with the KPA and how you set it up for Performance mode.

Well, at the moment I am using a Line 6 M5 and an Eventide H9 with the Kemper. I am using the Remote and sending midi from the KPA to a Midi Solutions thru box to the M5 and H9. They are wired in series in the KPA loop.

Here is an example of how I use them in Performance mode...

In Performance slot 1 I am using an H9 shimmer effect.

In Performance slot 2 I am using an M5 seeker effect

In Performance slot 3 I am using an H9 delay.

So in Performance slot 1 I want midi to turn on the H9 and select the shimmer effect. That uses the 2 midi messages I can send from the KPA.

In Performance slot 2 I want midi to turn off the H9 and turn on the M5 as well as select the seeker effect in the M5. That would require 3 midi messages. I only have 2.

In Performance slot 3 I want midi to turn off the M5 and turn the H9 back on and select the delay effect in the H9. Again 3 messages.

With the ES-8 I could send all of those midi messages and make all of those changes. Unfortunately it would require a lot of programming unlike the Remote.

Maybe I'm missing another way to control these devices using the Remote and KPA. I've posted several questions about it on the forum and still have no answer on how others are controlling multiple outboard devices in this manner. There has to be something I'm missing.

I'd rather use the Remote because the button assignments are listed on the screen and it's so easy to set up. Maybe I will throw adding a 3rd midi message in Feature requests.

One thing I considered is looking to see what the on/off PC messages are on the M5 and using the reverse on the H9 but then I could never use them in tandem which I do once or twice. I believe this would require running both with the same midi device number which I always was told wasn't a good this to do. Not sure the truth to that.

In a perfect world I would not even use the M5 but the seeker effect is an integral part of a song I've recorded with my band and I cannot get the H9 or the KPA to fully replicate it yet. Also the square wave trem is the best of the bunch (the KPA doesn't even have a hard square wave). The M5 activates the second you stomp on it so if you have good timing you can get it trem to sync very well. The H9 has a lag when you activate it, so getting it to sync is hit or miss. Our drummer plays to a click and my presets within the H9/M5 match the bpm. So if I can hit it right on the 1 I can play the whole song and never have the trem get off.
