Windows 10 Professional
Audio is routed out of a firewire 400 card into a Yamaha Motif XF8 keyboard and the keyboard has 2 quarter inch phono jacks plugged into a 16 channel USB mixer (the mixer is output to an Ultracurve Pro DEQ2496 equalizer which then outputs to a studio subwoofer with two preouts for the stereo monitor speakers). The PC itself does zero audio playback, everything is passed into the Motif. I am perplexed because Synchron FX through the smart orchestra is the only thing I have ever had any audio issue with. I have had this issue since it was released, but I expected the kinks would have been worked out by now...
I have tried rebooting the keyboard and the PC. I have checked for driver and bios updates on both the keyboard and the PC, and where necessary, updated them (I am a security conscious guy so this is part of my regular weekly PC maintainence anyway). All pertinent software is up to date, including all Vienna software and windows itself. I do not run a virus scanner, I only use whats built into Windows (again, being security conscious, if you put the right protections in place, there is no reason to run a virus scanner, provided you are careful).
Hopefully this helps, Ill have to see if I can somehow get an audio capture of the noise it puts out. I can mute the channel of the problematic track (shimmering is one of the FX tracks that I cannot use, Ill have to see what the others are, almost all of the "plucks" in FX 1 are unusable for me) and continue working with other channel in the same audio file, but the channel, once it starts creating static, continues to do so, getting louder and louder until the audio line is saturated. Im thinking maybe its one of the effect types that you are using (I was thinking maybe its the delay effect).
Im also perplexed why Synchron isnt picking up the FX on a track when exporting audio from Cubase...
