I’m thinking about a pipe that, once received certain note on one MIDI channel (from an Octatrack connected to Midihub In A), transforms this trigger in sending value 0 to ALL CCs to some specific port (where a Faderfox is connected, Midihub Out D), so all these CCs are initialized in the Faderfox -check “diagram”
So all CCids meaning one event in will create 128 outgoing?
16 Transforms to note ids 0,8,16,…,120 then see  below. 18 pipes but instantaneous
Or you can try the LFO route
A 1-shot LFO (saw-up, 128hz res) would give 128 CC values which you can then Transform to 128 ids all with value 0.
that would take 1 second. 2 pipes.
If that’s too long you can do it at 8Hz ( giving values 0,8,16,…), Transform them to notes (on some unused channel), Harmonize them to get 8 notes from each one, then Transform the notes to your CCs.
that brings you down to 1/8 sec. 4 pipes
If that’s too long, you could try several 1-shots with different phases running at 16 Hz or more
There might be a nicer way but that’s the best I can think of now.
