I guess my dream of simply plugging in two midi cables, setting transmit or receive and omni or same channel and having full synch was a fantasy.

Here, it gets more complicated with USB & MIDI DIN sharing the port, and inserting H9 Control into the chain.  Maybe less so with the new 'Connect MIDI Device to Eventide Device' option.  I like having all of the individual MIDI settings for versatility.  It can get complicated when you switch 'MIDI modes' a lot.

Fortunately, the 'MIDI mode' switches almost become second nature with enough repetition.  This did prompt a thought: saving the entire System Settings for each pedal as a .syx file.  Not necessarily easier, but something for me to try here.

That was my thought.  I haven't tried it, so I can't confirm.  But I was thinking of cobbling together a similar box for the expression output of my EHX 8 Step Program.

Yes, that's the whole idea behind my somewhat convoluted MIDI setup.  This pair of harmonies goes with that set of delays at this modulation rate, etc.  Most can be done with sync'ed MIDI Clock, but the specialty routes need synchronized variable control.

MIDI Clock is independent of MIDI Channel, so it does apply across the board.  MIDI Clock Out enabled in the transmitter; MIDI Clock Input enabled on the receivers.  But it does get a little funky when H9 Control is involved.  Somewhat counterintuitively, you need to switch that around.

Think of MIDI Clock settings as belonging to the MIDI DIN plug system, not H9 Control.  So, to use Tempo On and BPM adjustments in H9 Control, set the MIDI Clock – MIDI Input to No in the pedals.  While you're there, set MIDI Clock – MIDI Clock Output to Yes.  Now the current BPM in H9 Control (per pedal) will be reflected in the pedal itself. The LED displays should update the second that you hit ENTER, after double-clicking BPM & typing in a new value.

It's almost a necessity with more complex systems like yours.  It's one thing if you just want to hit a PC switch, and have the presets locked together from multiple pedals.  Quite another thing to make adjustments across the board that synchronize with other settings.

Effectively, that's re-programming the presets on-the-fly.  With hands & brain occupied, your feet are the only things left to act as a mixdown engineer.  I try to do as much of the dirty work in advance, and consolidate it all into the least amount of tap-dancing.  Features like the HotSwitch & EXP PED routings give you 2 or more presets in one.
