Have you got midi in & out connected? If so you may be creating a midi loop. Try it with only one cable, OT out to Virus in.
I use only one cable , no midi loop
Also are you connected via usb to your computer in Ti mode?
You should be able to select midi source as midi in or usb or both, you can on the Virus Ti!not sure to know how to change the setting but I noticed that following issue:
1- I connect the OT with a midi cable to the virus... I got from the virus some strange audio noize!
2- I connect the Virus via USB to my computer,
3- I launch ableton live, I put the VST plug in Virus TI SNOW on a track,
4- I change in the VST the configuration -> part 1, 2, 3, 4 -> OUT L+R (and not USB 1).
5- I disconnect my USB cable.
6- I connect the OT with a midi cable to the Virus..
7- I get a nice sound from the virus! it works..
8- I put my VIRUS TI SNOW asleep, I awake the virus, then I launch a midi sequence from the OT, the virus sends me back strange audio noize.. I need to go to step 2 to get a nice sounds
I don't understand the issue, could it be that I need to STORE my setting in the VIRUS ? change a param in the machine???
Don"t know! can you help?
Cheers.
