Connecting 5150iii and GFI Specular Tempus to HX Stomp via midi simultaneously

[criffles]

Hey there,

I'm quite new to the midi game and I wasn't sure what cables were needed to physically connect BOTH the 5150iii and the GFI Specular Tempus to my HX Stomp simultaneously. I can connect them both individually and send midi signals no problem but I want to run both together.

Is it possible to run a 5 pin midi cable to my 5150iii as usual and then a usb midi cable to my HX stomp?

Cheers

Since both devices have only a MIDI IN port, you would need something like this:

 

MIDI Solutions Thru; Two Output MIDI Thru Box

 

According to L6 Support, the HXS should provide the necessary power for the Merge:

 

Hello rd2rk. Your Line 6 Support Ticket was updated with the following message:

 

Hi Edwin, thanks  for writing. According to engineering, we follow the MIDI standard on pin out, technically there is +5V on pin 4 of the MIDI out jack on Helix. It's through a 220 ohm resistor so not much power is available.

 

If I had to hazard a guess, it will work but I don't know for certain if we've tested using a MIDI Solutions or similar device in such manner to make any recommendation.

According to MIDI Solutions this should be sufficient, but:

 

Thank you for your inquiry.

 

The MIDI Solutions products require only a small amount of current, so 5 V though a 220 ohm resistor is sufficient, however it's also important that the center pin 2 is grounded as indicated in the MIDI specification. If you have a multimeter you can measure the Helix's MIDI output voltage between center pin (ground) and the pin next to it in the counterclockwise direction, if you observe a voltage above 3 V it will successfully power the MIDI Solutions MultiVoltage Thru and Quadra Thru. If the Helix does not provide power there is a workaround which is to first connect its MIDI Out to the MIDI In of some other MIDI device, then MIDI Thru from that device to the MIDI In of the Quadra Thru, and then from the Quadra Thru's MIDI Thru outputs to your remaining devices. If none of your other devices have MIDI Thru ports then the MIDI Solutions Power Adapter can also resolve the problem, for more information on the Power Adapter see www.midisolutions.com/prodpwr.htm.
