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.
