It seems the issue is that you use a custom synth-plugin (Calf Wavetable), that is not a general MIDI (GM/GS) compatible synth, but selected a naming schema “General MIDI”.
So Ardour displays MIDI patch names (like Cello) due to the naming schema. But that does not correspond to what the plugin does.
No surprise there. Calf Wavetable does not support this.
Yes, you’re right. That’s what i misunderstood.
I’m running a selfcompiled Ardour 6.9 under Ubuntu,
any chance to find the GM compatible synth by it’s name ?
I have some Soundfonts from my (former windows) GuitarPro5.
Can i use them for “ACE fluidsynth” ?
Or, better for “General MIDI Synth”, I always prefer to user x42*
The better question is, how can i change soundfont in “General MIDI Synth” ?
If they are sf2 format soundfont files you surely can. I don’t know about “General MIDI Synth” (for some reason is not working on my system), but in ACE Fluidsynth you browse to find the sf2 file on your filesystem and load it. Then you choose the appropriate channel and it should be working.
