DM7-MIDI Pro Adaptor.

Ok so i have been looking for a way around the problem with modules that output midi Via USB and i think i have it but before i buy what i need, i want to ask the community in general if anyone has tried this.

Take the USB cable, plug it into a USB-Midi cable, then into the MIDI Pro Adaptor and into the game. Is this possible? will there be major lag? Anyone know?

What you're suggesting won't work.

You'll need to plug the USB from your drums into a computer running something like MIDI-Ox. Then USB-MIDI will connect the computer to the MPA.

Do you know why it wont work? Im not surprised i was just wondering the reasoning

[ZigZag2005]

Not with any certainty, except to speculate that your typical USB-MIDI interface simply wasn't designed to use in the manner you suggested.

Just to sate my curiosity, I decided to see if this works.

I used a M-Audio Axiom 25 as a USB-MIDI source, an Edirol UM-EX1 USB-MIDI cable, and an unconnected, powered USB hub to connect the two. There was no activity indicated on the Edirol, or MPA, in this configuration.

Once I connected the hub to a computer running MIDI-Ox, the Edirol lit up, and everything played on the Axiom was transmitted to the MPA.

^I don't get it. Why would you use a USB hub to connect them? You plugged the MPA into the USB hub?

To properly test this you'd plug the usb output of a device that has a usb-midi output into a usb to midi adapter cable and plug the midi output of that adapter into the MPA. Then plug the usb of the MPA into your video game console.

In my case, this is not possible, because the USB end of my Edirol is male A-type. The keyboard uses female B-type. I don't happen to have a B-type male to A-type female USB cable.

In any case, it would not have worked because if I did connect the two directly, there would be no power source, as is the case in the scenario you describe.

And no, the MPA was not connected to the hub.

may i ask what exactly are you connecting to the Midi adapter????

[jimhenry]

The reason that you can't hook a USB-MIDI keyboard to an MPA using USB to MIDI cable is that USB requires a USB Host at one end and a USB device at the other. Among other things, only hosts provide power. Almost everything USB is a USB device. The only common USB hosts are computers. The keyboard and the MPA are both USB devices. The can't be connected directly together. They each have to connect to a host that passes messages between the two devices.

Ok so now i think i have a chance to get this to work but i need help. I cant find a good tutorial that helps so i am asking the community. Like i said i have an Alesis DM7 with USB midi out. I now have the MPA and a USB to MIDI cord for my computer. Everyone says to hook up the drums into my computer then into MIDI OX then into the MPA but i cant figure out how. Can someone explain it to me in slow, detailed directions?
