USB/MIDI cable

Hello.
I want to use my keyboard medeli m10 (cheap) on my pc. But i have a problem/question. The -midi out/midi in- in the keyboard  is an usb B. So i bought an adapter. Then I connected it to my pc via usb a - usb a to my onboard soundcard. The problem is that I get  huge latency(1/4secs or more). I guess the problem is my soundcard... So... I have a digi002, it has the normal midi inputs(5pins)1 midi in 2 out. Should i buy a midi usb cable? I ask this because i think the midi usb cable usually goes from keyboard (5pins) to the soundcard usb. What i want to do is the inverse. From keyboard(usb) to the digi002 soundcard (5pin midi in/out). Will it work?
thanks.

The adapter changes the USB B female to an USB A female. So i use a standar usb cable (A male- A male) and connect it to the pc's usb.
Maybe i didn't explain it well(not so good english) I connect from keyboard usb to pc usb, so im using the onboard soundcard. My digi002 doesnt have  usb, just 5pin ports.
So, there's no way to use my digi002 with this keyboard? What a shame.
The latency i get connecting it directly to my pc makes it impossible to record. I've read some people say that i should install asio4all drivers, i install it but i can't select them in sonar 6. I can select ASIO only.
Thanks for response


Yes, like the midisport uno. Yeah that was what i thought. I have the inverse. Usb keyboard and midi interface. Crap.

The medeli m10 uses usb for both audio and midi. The most standard cable for USB connection of a peripheral to a PC is the male B to male A cable. Your adapter is probably not hurting anything though. That keyboard design allows it to be played by a sequencer program by midi via usb while also capturing its audio via USB.

There is no way for a PC MIDI driver & midi cables to carry the USB signals required by the medeli m10 or any other USB device, so your proposed inverted use of the USB midi adapter would not work.

But latency is usually not caused by the MIDI input path. The usual cause of latency you hear while playing is the audio output path, particularly with PC built-in sound devices and their drivers. But you want to use the digi002 for your sound output, right? There should be a way to get good latency using that, no?

The latency you hear is between what and what?

Is it when you play the keys and then hear the sound generated by your keyboard sent (by usb) thru your PC and back out through the sound card and its connected speakers? What about the speakers on the keyboard?

OR --- are you using the keyboard to trigger vst synth sounds in Sonar and they are slow to come out the PC speakers?
OR -- are you using the keyboard to trigger the midi synth built into your PC sound card?
OR -- are you actually using the digi002 for sound output?

You are on the right track to improving the latency (eliminating the pc soundcard synth). Next question would be how to get sound directly out of your digi002. I assume that you have already connected amp/speakers directly to it, and not through the PC sound card. Also, I assume you have tried adjusting the latency when you are using the sigmatel drivers.

This could be a topic for the Sonar (producer?) forum. Someone there will know how to get you going with the digi002. Describing the setup and audio connections will help.

I managed to lower the latency to 5,3ms. I think that's acceptable, no?
I reinstalled Sonar6 and in the new installation i selected asio drivers, then the asio digidesign 1 as output. And it worked.
I tried to do that before but my Sonar crashed, so i reinstalled and worked.
Thanks everyone for the tips and all.
