Hex problems

[manymanyhaha]

I have 6 Hex, each set to a different midi channel (2-7). I am trying to control them with a Morningstar MC6mkII which is capable of sending multiple PC messages over different midi channels.

Three of the Hex are behaving as expected. The other three just behave when they want.

Right now, there are two presets. Preset 1 turns all loops off channels 2-7. Preset 2 turns loop 1 on channels 2-7. Sometimes the three misbehaving ones respond and sometimes they don't. I wonder if those three are overwhelmed with 6 PC messages passing through for some reason and the other three are not? If I only send one PC message to each (as opposed to 6), they all react as expected.

Any ideas?

Are the misbehaving units the first three in the path or the last three?

What is the complete MIDI path, and are you sending anything other than the six Program Change messages?

[manymanyhaha]

Now that I've gone through and done a ton of programming on them, it's really the last 4 in the chain that sometimes don't respond to the PC message. I have to resend the messages two or even three times for them all to respond correctly. And yes, right now, just sending the 6 PC messages.

I think I am going to try a midi splitter and see if it works better in parallel rather than a serial chain.

So have a Quadra Thru and that's what it is. One Hex will forward to another every time but when you add a third one to the midi chain, it doesn't always relay the PC commands through.

I'm glad it works using the Thru, but it should have worked in series just as well.

Did the problem persist regardless of what order the HEX units were connected?

So if the problem was shown to be when wired as follows:
Controller -> HEX #1 -> HEX #2 -> HEX #3 -> HEX #4 -> HEX #5 -> HEX #6 (maybe first make sure it isn't just the MIDI Cable between HEX #2 and #3)

What happens if you swap HEX #1 and #2 with HEX #5 and #6 for instance, so as a test the order would now be:
Controller -> HEX #5 -> HEX #6 -> HEX #3 -> HEX #4 -> HEX #1 -> HEX #2

Let us know what you can, or skip it if you prefer and get to the important part of playing this monster rig now that the thru seems to have solved the trouble.

Apologies, went camping for a couple weeks.

It doesn't matter how I arrange them or the cords. a second hex does not always want to forward to the third.

Have you considered making PC 0 be able to mute the inputs? Would be unbelievable useful.
