| Summary | 0009837: Ace Fluid Synth - Uses the channel information based on previous soundfont loaded | ||||
| Description | This may be due to the same issue I mentioned in the following bug report https://tracker.ardour.org/view.php?id=9836 Kind of hard to explain. It appears that if you open a soundfont1 that contains more than one patch, it will load each patch into its own channel, which to me is the expected behavior. However, if you replace that soundfont1 with a different soundfont2, you will notice that the first soundfont1 channel patch number information used, is then applied to the soundfont2 channels. | ||||
| Steps To Reproduce | Example: Say you have two soundfonts STRINGS = 5 patches SoundfontGM = 128 patches TEST A In a new instance of Ace Fluid Synth, if you load up SoundfontGM first, its first 16 patch names (of the 128 patches) load into the 16 channels, which to me is expected behavior. TEST B In a new instance of Ace Fluid Synth, you load up STRINGS first, its first 5 patch names load into the first 5 channels which is expected. In that same instance of Ace Fluid Synth, if you then replace that STRINGS with SoundfontGM and look at the channel section, you will notice that now the first 16 patches are not loaded into the channels the same way as it did in TEST A. It is now using the patch number information based on the previous STRINGS soundfont instead. So it is holding onto that information from the previous soundfont (STRINGS) even thought that soundfont is no longer loaded and applying it to the new soundfont (SoundfontGM). | ||||

That is more or less correct. The bank/patch information kept by Ardour's MIDI Track (not the synth). The synth does not keep track which patch is loaded on any given channel and changing a soundfont (or even synth) does not change the bank/program assignment. I have now fixed the case that no explicit bank/patch messages were sent to the synth. That was indeed an issue. Fixed in Ardour 9.0-pre0-349-gc9645723de |
