I’m running Ardour 6.9 on AVL-MXE-2021. Mainly working with midi recording on DecentSampler and Sfizz.
Ardour and Jack are both running at a sample rate of 44100 and 512 Frames/Period. That works well to get suitable responsiveness when recording from a keyboard in realtime.
My time has never been great, but I know when I’m on the beat and when I’m not. I find that when I’ve recorded something that feels like it has solid timing when I come to play it back everything feels uncomfortably early.
So at 120bpm notes seem to be moved about 1/32 note earlier than where I played them.
I understand that both Ardour and Jack compensate for latency. And I know I can further compensate in the settings of the plugin. But it feels like the compensation, if that’s what it is, is excessive.
Might I be missing a really obvious setting? Or is there anything else you can suggest?
I’ve been having the same issue on 6.9 but inconsistently. Like the latency compensation would overshoot sometimes but I couldn’t find a reproducible set up.
Thanks for correcting my misunderstanding and for the suggestion.
I’ve changed the settings so I’m using ALSA. I’m using a powered Behringer UMC404HD interface. Systemic latency was caIculated at 12.8 ms (564 samples) when I ran the calibration so I tried those settings.
It seems to make a slight improvement but really the problems persists. Timing in regions feels “solid” when I record them. But on playback the midi notes are slightly early with reference to the click and the barlines.
I can make things worse by increasing the settings from what I got after running the calibration. But nothing really makes it better - it’s not possible to set negative values.
Likewise changing the Hardware input/output latency in the main Audio/Midi setup window only makes things worse.
I tried replacing the built-in click with drum hits quantized to the grid. Still no improvement.
