I upgraded to 4.11 at the same time as I implemented a Roland HPD15 handrum. I record midi clips with the handrum, and routed back into the handdrum.
Whenever I use the crossfader, the tempo of the live project slows down, then springs back chaotically like a rubber band.
My soundcard/Midi is the Presonus Firepod. There are no other midi modules besides the HPD15. I am using an evolution MK249C controller to control the tempo via slider, but have tested the setup without the MK249C with the same result.
Thank You
