MIDI Clock always behind time

Getting Stuff Done How do I .... ?
#1

Hi there,

I’m using Ardour/Mixbus on Linux and I have problems to get a tight/working MIDI clock. The generated MIDI clock is always behind the time of Ardour/Mixbus. I tried various Jack/Alsa settings (Jack MIDI, Alsa RAW devices, etc) without success. Other programs like Renoise or Bitwig are generating a really tight clock signal, they use Alsa Midi devices.

Any tips to create a tighter clock signal with Ardour/Mixbus?
Is there some kind of latency setting for the clock signal?

Thanks in advance!

Please file a bug report and include a LOT more information. Version of Ardour, version of ALSA, devices in use, how you are measuring timing, what the offset/jitter is, etc, etc,
