Hi synthesis, Robin, Chris and all
now I had some time to experiment with the latency compensation settings.
When playing around with different audio input and output latency compensations the results were not satisfying in my opinion.
So I kept the audio latency compensation determined by Ardour at 99 samples each.
And what can I say? The midi latency compensation has now solved it best, so far!
I have three drum tracks here, all hitting at the same time at the beginning of each bar (aka four-to-the-floor): the first is my Akai XR10 external drum computer, the second is a Geonkick virtual instrument, and the third is the rhythm section of my Roland D110 vintage synth.
The lowest audio recording track in each case is recorded with the audio and midi latency compensation settings calculated by Ardour. The upper one with unchanged audio latency compensation and my own midi latency compensation settings. This did the trick.
The 160 samples of systemic input latency was calculated by Ardour. I only increased the output latency.
Even though I have now achieved the desired result, I am not quite sure if this was the right way to achieve the goal
Any suggestions or hints on this?
P.S.: For the very attentive: the offset in the two Geonkick audio tracks comes from the fact that I adjusted the midi event of all three tracks after the first recording, because Geonkick played too early.
