Well that was a bit disappointing - getting a lot of crackling from Union after going through a few presets - not happened before with that synth though it has happened with Sampletank 3 but restarting CbB has always solved it. I restarted PC and altered buffer rate but no joy. It was even worse in Live 10 Lite! Be interested to know if anyone has same problem. CPU monitor in CbB is not showing anything untoward
