No patch bank available

I use ardour since a few weeks. And already made a few songs. Since one day out of nothing without change anything I can´t choose new midi instruments.
There was this „general midi synth“ that once appeared automatically when I set a new track. But it´s gone and I cant find it anymore. It is not available. Instead when I now open a new track there is automatically „ace reasonable synth“ which has no patch banks available.

If I choose another available synth such as „ace fluid synth“ then I cant choose patch bank too and can´t hear anything although – based on the volume control - I can see that there should be a sound.

I don´t know what to do anymore. Please can someone help me!?

Which version of Ardour is that (Menu > Help > About)?

Ardour 6.9.0 after bach (rev 6.9) intel 64 bit

OK. I have no immediate idea, then :frowning:
I’ve asked because current nightly builds (Ardour 7.0-pre) have an issue that could explain this.

Is “General MIDI Synth” unavailable in general? If not, perhaps only the default synth was changed in the Preferences?

I still have “general midi synth” in the projects I once created. But also if I ad a new track in this older project general midi synth is not available anymore…

But I´ll have a look at the “preferences” where can I find it?

If I can chip in, out of curiosity, I checked on my system (also 6.9.0 Fedora build) and I don’t see any “General Midi Synth” in the available instruments …

Independently from this, I also don’t see where in the Preferences one can set the default instrument to be used for new MIDI Tracks/Busses… No such thing in the “MIDI” section of the preferences nor is it in the Session properties :thinking:
Note that I personally don’t miss that preference … it’s just a click in the new Track dialog … or one can use templates.

@Gogogoing a quick remark related to using ACE Fluid Synth which you say you tried.
Fluid Synth doesn’t do any sound on its own ! it’s a plugin that let’s you use SF2 SoundFonts so you have to give the plugin a SF2 file to load and only then you’ll be able to pick an instrument/patch/bank :wink:
When you double click on the plugin:


This is also where you can then assign a default instrument to each MIDI channel

If you don’t have any SF2 to play with, here’s a soundfont of the old Roland Sound Canvas that’s GM compliant)

https://musical-artifacts.com/artifacts/538/Roland_SC-88.sf2

It is bundled with binaries from http://ardour.org/download.html. Many GNU/Linux distros do not package it.

You can get the source from GitHub - x42/gmsynth.lv2: General MIDI LV2 Synth or a binary from x42 General MIDI Synth.

Thanks so much for the help of you two! What’s funny is that it always worked and then from one day to the next no more. . . I´ll try to fix it with your pointing out.


This is the “general midi synth” i´v been talking about. This was available from the first moment I used ardour.
