Convert midi to audio in ardour without rendering out

i use windows vst with linvst
midi track sound is ok
but when i record from this track quality decreasing

As @seablade asks, how is the quality “decreased”? Do you have your fader or gain up too high away from unity and the sound is clipping? Are you recording into a mono instead of stereo bus? Do you have a plugin on the bus that is mangling the sound? I concur that under normal circumstances the recorded sound should match the sound out of the MIDI instrument.

I, too, have used linvst until recently and never experienced a degradation of the sound when recording the output to another track.

stereo bus for record ? how to?
i record in a stereo audio track
for linvst some windows vst dont fine work with it
in end
i test most vst with wine and linvst but some vst…

@remyzerems @seablade thank

Not record but stem export. Just select that channel in the export dialog: https://manual.ardour.org/working-with-sessions/interchange-with-other-daws/stem-exports/. It will be faster than realtime.

Also, did you try adding a MIDI port + synth to an audio track if you don’t require the actual MIDI data?

You can right click on a selected midi region, “REGION” --> “Bounce (with processing)”.
Or select the midi regions with the range tool, then right click and “Bounce Range to source list with processing”.
It will create a new audio region in the sources tab assumed you have inserted a synth plugin or something similar in your midi track.

That’s incorrect, I’m afraid.

why???

EDIT: I stand corrected! You can…just not freeze. My first response to OP remains valid that there is no way to freeze/bounce in place i.e. without rendering out.

You can use bounce with processing with MIDI regions. A new audio region will show up in the source-list. It can then be added to an audio track.

What is not possible is “bounce + replace”, since that would have to change the track type from MIDI to audio. Likewise “freeze track” is not possible for MIDI tracks for the same reason.

Is there a way to add it to the exact same place in the timeline without having to manually drag it to place?

i see “bounce + replace region” in action buttons list what is this ??? and how to work

It’s for audio only.

plz optimize for midi

As Robin said previously, midi --> audio would require changing the track type. It’s not like Reaper or Samplitude where the tracks are catch-all and change dependent on the material added.

I see at least three faster-than-realtime solutions that don’t require too much work: 1) Record midi direct to audio by adding a midi port to an audio track (and disconnecting the audio inputs) and completely remove the need to “freeze” or 2) create an audio bus, route your midi track into it and render a stem to drag back into your project and 3) the method which @krischan941 suggested above.

It all depends whether you need to edit midi or are OK treating your midi instrument like a traditional audio recording which, of course, can still be edited in great detail with patches etc.

technically this is impossible because midi is just midi notes on or off… The easy answer is the one bachstudies mentions, which is to make Ardour route synthesize a MIDI track onto an Audio one, and then you can use further things with the audio waveform data that you can’t otherwise do on the midi track.

If you’re thinking of repairing something with MIDI gates to have more control over how “synthesis” is working for each note, there’s a special plugin I previously posted about as this might sound what you’re looking for. There’s ways you can change the BPM of a re-factored MIDI instrument plugin but still be working within the MIDI Track. Essentially it’s a “wrap-around” plugin that can help “tune” your MIDI instrument plugin with various parameters… — if this interests you, it would be the non-free DiscoDSP Bliss plugin with its “resampling” features…

I’m confused. The OP asked for a quick way to convert MIDI to audio without rendering out. What does Bliss have to do with this?

it sounds like he wants to manipulate audio on a key-note basis, something which discodsp bliss should be able to provide.

I think he literally wants a fast way to convert midi to audio. No more, no less.

ok
thanks guys
