With the MV-8000 as master, sequencing my Virus TI and the OT slaved, everything is rock solid. No sync drift, latency or unwanted patch edits in the 30+ minutes I’ve been running, even with pattern, patch and tempo changes. Exactly as shit should work. I’ll open a ticket after this project is finished in November, I just have way too much to do right now. The Virus in stand alone mode is a solid piece, by the way. The latency complaints you read about are almost universally experienced under the USB host which is out of the picture in my scenario. This box has been out for 14 years and is pretty well prevalent so I’m not sure I’d assume the issue is with the Virus flipping bits and mangling midi input. Surely the masses would have raged about this by now? Thankfully, one doesn’t seem to lose any performance features of the OT when it is slaved.
Hopefully Elektron have a debug program I can run for them. It would be interesting to see what something like Wireshark would capture.
