I think this is incorrect. The POD HD500 has dynamic latency as well and each effect added does indeed add a tiny bit more latency. In order for more effects not to contribute to the over all latency, the max latency would have to be calculated and fixed.
Could you elaborate a bit on this? I had the HD 500 as well and never noticed this. Has this topic already been discussed and was it confirmed by Line 6?
As I understand, latency gets introduced with an A/D conversion. But after that? In the digital domain? By another effect?
Adding another effect will increase CPU load, but latency?
