Passing MIDI Clock through HX Stomp

[mjkatz914]

I am using an HX Stomp with latest firmware.  I have StudioOne5 and just purchased an ElectroHarmonix 1441 looper running in the effects loop of HX Stomp.  I can synchronize echos and looper within the HX stomp with clock from USB midi from StudioOne with no problems.  I also use a handy little midi switch from JetMicro.   The Jet is using the conventional midi in and I have midi out to the EHX looper.   I can set the midi clock on the EHX from the Jet tap temp with no problem.   The issue I have is getting the USB midi synch from the computer, that is working fine with the HX Stomp echo, to pass clock to the EHX.   I have enabled midi pass through and set RX clock to midi and USB/midi, but no combination will get the midi clock to synch both the HX Stomp and EHX 1440 looper.   It doesn’t seem to be able to be done with any combination of settings I can find.  That being said, I’m just a basement jammer.  Any pros out there have an idea how I can get the USB midi clock to pass through the HX Stomp to the EHX looper?   Many thanks!    Loving the HX Stomp by the way!

If you're getting MIDI Clock into the Stomp over USB from StudioOne, if you turn on MIDI THRU in Global Settings>MIDI/Tempo, that should pass the clock thru the Stomp to the EHX.

Thanks rd2rk.  I tried this but the clock isn't being passed.  I think this could be a bug, but I don't have the knowledge to say.   I'll try with Line6 support.

So after working with Line6 support, the solution is to set the Clock RX to USB from auto.  The Jet midi pedal seems to send clock on MIDI and the HX is confused about which to listen to.  For now, that's a workable solution to get my computer and drum patterns to synch up with both the HX Stomp and ElectroHarmonix 1440.

A bit on this topic - HX stomp is receiving MIDI clock RX from my Logic via MOTU or presouns interface (doesn't matter which one).

Then I'm trying to pass it through HX stomp to other equipment such as Novation bass station or Moog Little Phatty.

 

For some reason HX is doubling the tempo - 120 becomes 240 etc...

 

When HX stomp is removed from the chain both synth receives good time signature. 
All global settings at HX stomp are correct.
Also when using HS stomp as a tap tempo and clock TX for synths this works perfectly fine.

 

Any idea on why and how this is happening?

EDIT:

You need to turn OFF MIDI clock TX or MIDI thru, then it works. 
This makes sense ;)

I see the same thing, but when you say it makes sense to turn off MIDI clock TX or MIDI thru why does that make sense?  I still want the clock and the midi to go through the HX stomp. 

 

Here's a video showing the issue:

ok. you are right.  turning OFF Tx MIDI Clock fixes the double time issue, but I have no idea why.
