| Summary | 0010014: Feature request: possibility to use separate/different MIDI system than audio (ex. PulseAudio sound backend, JACK midi) | ||||
| Description | As i explained in a previous bug report, sometimes i use PulseAudio with a large buffer to avoid xruns on my low-latency JACK server, with PulseAudio itself running as a JACK client. This setup works great, but with one problem: there's no MIDI which i need to trigger sound in some instrument plugins. Would it be possible in a future version of Ardour, to use a MIDI system other than the selected audio/soundcard backend? I'm guessing this would also benefit those who, for example, use JACK for audio but would prefer to use alsa MIDI without a tool like a2jmidi. | ||||

That is not reasonable since Audio and MIDI may or may not align. Also PulseAudio is really just for listening when on the way home in train or sth where quality isn't any constraint. One should not use for any professional work. Why not just change JACK's buffersize or use pipewire? |
|
|
Forgot to specify, need to click "start" when the audio/midi setup window first appears at startup |
|
|
> Why not just change JACK's buffersize or use pipewire? Because i need low latency in JACK, and it's annoying to have to edit my config files each time to change the buffer size. |

you can change it at runtime, no config edit need. Either in Ardour's Window > Audio/MIDI Setup or in a terminal window: jack_bufsize # prints current value jack_bufsize 1024 |
|
|
> jack_bufsize 1024 Yeah that may or may not work, depending what software is running, what interface i'm using etc. ALL of these must report back that they have acknowledged the buffer/samplerate change and support it. It doesn't work with my m-audio fasttrack ultra (even with just JACK running) which is where i need this feature most. |
