Indeed it’s two different settings, one is logic’s buffer size, one for the hdx driver. If you set logic to 32 samples but don’t touch the hdx driver, recording percussive material will be hard. If you set both to 32 samples you should come to a roundtrip latency of approx 3ms at 44.1 which seems pretty fine to me. Sure not entirely what hdx with PT does but a lot better than the standard 17ms at 256 buffer size…
