Midi input Voice Live Play GTX

Olivier

Good morning
I have a Voice Live Play GTX which apparently has a MIDI input but no output.
I would like to send midi commands from Peter's great application, to trigger vocal harmonies or change guitar presets for example.
What should I buy for this please? The widi master seems to be powered by the midi output but there is none on the gtx, only the midi input (there is however an auxiliary mini jack input but I don't think that this allows powering the 'MIDI input by plugging in the mini jack intended to connect to the output normally...?)
Is there a wired way to connect the iPad to the GTX? And in this case would this power the iPad?
Thank you for your answers
Olivier.

Olivier you would need the widi Jack which you would need to power by usb c and just use the midi in cable.

Olivier

Lishy
Thank you for your reply.
As the iPad is less than 1 meter above (on the microphone stand) is there not the possibility of connecting by cable in this case? (Rather than multiple devices which will ultimately be powered by usb-c)

Lishy

Olivier I don’t think so, not unless you want to go from lightning to usb and then usb to midi.

peter

You can use any class compliant midi interface. It will automatically be recognized by iOS.

Olivier

Thanks. Reading the documentation for my Live Play GTX I also see that it is possible to receive MIDI control messages on the USB port.
Is it possible to connect a cable from this USB (mini port) to the iPad? Would the iPad be powered at the same time?

Olivier

THANKS @peter and @Lishy
I also have a question regarding the transition to VoiceLive 3 Extreme which is more complete and has midi input and output.
This pedal has 10 push buttons, do you know if it is possible through the midi output to assign, for example, buttons to start/stop playback, change titles, etc... in ST3 as we would do with an Airturn type bluetooth pedal board ?

Lishy

Olivier not sure. You’ll have to check the manual for that.

peter

Look in the manual whether the usb port is "class compliant". If not, it will not work on iOS as it would require drivers.

Use a USB powered hub, which connects to the iPad via the Lightning to USB adapter (or the USB-C to USB adapter). Then run the USB connection from VoiceLive and plug that in your USB hub. Voicelive and Stagetraxx should communicate and you can midi learn commands.

peter

A powered hub is only needed if you connect anything without its own power supply like usb audio interfaces. A powered device like the Helicon should work without a hub.

Hi @peter,

So I ordered a WIDI jack and connected it to the midi input of my tc-helicon Voice Live Play GTX

In the Stage Traxx 3.8 config, the Wi-Fi is recognized and connected.

The problem is that I cannot send midday orders.

For example, I read that the CC28 command allows you to press the "HIT" button (blue light for vocal harmonies).

I tested several syntaxes, including this one for example to trigger the harmony at minute 2:26

[midi@02:26.0:CC28.127@1]

and nothing happens.

What should I do please?

Here are the 2 pages of documentation that are in the manual

Olivier

I just realized my mistake!
A space was missing in the syntax before CC!
It was necessary to write:
[midi@02:26.0: CC28.127@1]

On the other hand, I can press HIT but not change the preset (the other 2 buttons up and down on the VLP GTX...)

Lishy

Olivier the syntax would’ve still been highlighted blue with or without the space wouldn’t it? At least it is on mine.

peter

The syntax highlighting rules are a bit more relaxed. They only look for „[midi“ at the beginning and then highlight whatever follows.

Olivier

Thank you very much friends for your answers, it's all good now. But how great is this app!
One more used feature!
