Hey Jacques, I have been trying to read about your issue I have the same kind of issue with my Infinity. I got it about a month ago to use with the BeatBuddy. Unfortunately I don’t have much time to play it as work and life is super busy. For some reason when using the BeatBuddy the Infinity will sometimes kick into this varispeed setting. I don’t know why and it’s definitely frustrating. I use the serial mode with one input, midi notes already turned off, beatbuddy midi into input #1. The Infinity might work a while, then out of the blue after I record a new pass it switches to some varispeed setting. There’s no rhyme or reason to it. I’ve tried to look into why as well, using the software and clicking off anything that says varispeed, but for some reason it has a mind of its own and will eventually goto varispeed. When this happens I reboot the Infinity, but it doesn’t always fix the issue. It’s just bizarre. Let me know if you’re still “free and clear” of the problem. I definitely am not as it resurfaces every so often. Would be nice for a future update to completely disable this function if the user doesn’t want it. I surely don’t!
