Helix LT Version: 2.80 Tap Tempo Pitch of Global Settings: Transparent Please be reported that when changing snapshots(with different tempo) in a preset, there are pitch shifting noises. I have downgraded the firmware to 2.71 and the problem is not found anymore. It is believed to be a bug in firmware 2.8. I would be grateful for a fix in the coming firmware 2.81. Thank you very much.
