As mentioned elsewhere we’re getting read to release version 6.7, which will be the last version compatible with older platforms: Windows (XP), macOS (Snow Leopard) and Linux systems built with gcc4.
Things are just about ready to go, but there have been some fairly radical changes in the last week to some parts of the code. We’re already fairly confident that things are still working correctly, but we’d appreciate some more testing - this will be the last version for these old platforms and it would be nice to make sure it’s as solid as we can make it.
So please consider downloading from the nightly website and give that version a spin with whatever your workflow tends to be. We’re particularly interested in making sure that all aspects of transport control are working correctly. That includes syncing with LTC and MTC/MMC and JACK Transport.
Positive feedback will be as valuable here as negative. We’re not looking for reports on new bugs per se (though those are always welcome over on the bug tracker ). We’d just like to be sure that none of the recent changes have broken stuff before we move on towards the future.
Remember that you can parallel install builds from ardour.org with each other, and with any Linux-distro provided versions of the program. They will not interfere with each other.
If all goes to plan, 6.7 will be the last release before 7.0.
As for compatibility, you’ll be fine. Relevant C++11 is available since libstdc++.so.5 (g++ 5.1, April 2015). Only Ubuntu 14.04, debian/wheezy (and similar 6+ year old systems) will not be directly supported anymore.
A user may not have gcc installed. A better test would be to determine if libstdc++ supports C++11, and specifically the recent gcc 5 or later version of it. perhaps

After that I need to type “cont” and press enter. Here’s what follows:

I type “cont” once again and Ardour continues and soon shows the Session Setup dialog.
I’ve tested and provided the example output after doing this - for some reason it didn’t make any difference. Should I logout/log-in or reboot for it to take effect?
Is this thread the best place for positive feedback? I’ve just downloaded and tried this nightly version
Ardour-6.6.489-dbg-x86_64-gcc5
running on Ubuntu 21.04 and it’s working perfectly as far as I can see, other than the DSP load being at around 50-55% instead of 30% which I’m going to assume is because it’s a debug build. Running this optimised nightly:
Ardour-6.6.493-x86_64-gcc5
and the DSP is back to 30% or so. This is mostly because I have a convolution reverb and a long IR which sucks up CPU. Let me know if you need any more details about the system but as far as I can see, it’s all working fine for me
Fedora mock build for rpm from git (rev 6.6-493-ga01377f168), Intel 64-bit) okay with just a few minor tweaks.
Installed and used it a couple of times and noticed some nice improvements, but no problems.
I noticed that with Linux/ALSA I can use an USB audio interface (e.g. Zoom H2n) for input, the system soundcard for output, and Zoom R24 as Mackie control surface. Simultaneously. Wow, I didn’t know that was possible…
That was a new feature in 6.0. It is also possible to use more than 2 devices, but there is no GUI for it yet.
One can specify more additional device using the “ARDOUR_ALSA_EXT” environment variable, semicolon separated with optional additional parameters such as sample-rate and buffersize if they differ from the main settings. e.g. ARDOUR_ALSA_EXT="hw:2@48000/512*3;hw:3@44100" Ardour6
PS. If you only use 2 devices, the output (playback device) is resampled. This is so that recording quality is not affected.
