Power on MIDI OUT port?

[catalano]

Does anyone know if the Helix floor will output power (+3Vdc or +5vDC) on the MIDI OUT port? I'm looking to use a Bluetooth MIDI interface that gets its power from the MIDI OUT of a device.

You can't power stuff over Helix's MIDI Out.

 

EDIT: I backpaddle a little from this absolute statement:

Hi,

 

You might want to take a look at using a WIDI device for wireless MIDI connections. See this post from @PierM who is a something of a wizard with this sort of stuff.

 

Hope this helps/makes sense.

The WIDI is exactly what I was looking at. It draws its power from the MIDI Out port of whatever it is connected to. That’s why I was asking if the Helix floor had power at that port. The reply above yours said it couldn’t power anything, but I see in the pedalboard post you referenced that he has it plugged into a Helix Stomp.  So I’d have to assume that the floor could support it as well. Thanks.

Let me backpaddle a little from my statement "You can't power stuff over Helix's MIDI Out":

 

A standard MIDI Out was never intended to power devices, but it is build to power an optocoupler. The max constant current you can get from a standard MIDI OUT socket (like all Helix devices) is 5 V / (2 * 220 Ohm) =~ 10 mA. This means 50 mW of power at best.

 

However that is enough to power devices that need very little power like the CME WIDI Master.

Thanks. I just ordered one. I’ll post back once I test it.

I just wanted to confirm that the WIDI Master works with the Helix Floor. I'm successfully sending patch changes to it from an iPad using the Set List Maker app.

Hi,

 

Widi Master and Widi Jack are fully compatible with any HX device. Widi Master will take power directly from the Midi Out port.

 

UHost doesnt work due a code wall in the firmware. CME asked L6 to fix the issue, but it will never happen.
