Welcome Djamel!
Test all the knobs. I bought my old Indigo over the net and it turned up with wobbly pots, which needed replacing. So test the knobs lightly and make sure they are all firm. (Sorry that sounded SO wrong)
Software wise, the latest OS version is OS 2.7 beta 4, which is meant to be more stable than the previous OS v2.5 release version. You can tell what OS version the synth is using when you turn on the Virus. - It displays the OS version on the LCD for a couple of seconds. You can update the OS easily enough yourself via [
Access' downloads] though, so this is not so much a concern.
Other than that, make sure the pitch and mod wheels feel ok and don't travel further than they should do. The pitch wheel should bounce back, but the mod wheel free-wheels up and down.
Some people have had issues with LEDs that are sometimes slightly lit when they shouldn't be, but from reading responses I believe is more an aesthetic problem than a severe fault.
Other than that, I can't think of anything else at the mo.
I think you'll be blown away by the crazy sounds it can put out. Hope it goes well.
Timo
