fluidsynth dssi problems

Hello, I'm very new to qtractor. I have a project with many midi tracks, many of which are going out to Hydrogen and two have each their fluidsynth-dssi plugin.

In the track properties of each of these two tracks I select bank and a different program - one track has a bass sound and the other a rhodes. They play fine.

However, after I save, quit and reopen the project, both tracks are set to bass or rhodes, depending which was the last I changed.

This is very strange, it's like if there were only one istance of the plugin, but there are clearly two - I can see them in the mixer, one for each track.

Am I missing something or is it a bug?

maybe it's not clear

I have a separate midi bus for Hydrogen which is set as output for all midi tracks except these two, who have the "Master" midi bus as output.

Re: fluidsynth dssi problems

Instrument mapping is historically aggregated by MIDI channel and output bus, so that you cannot have different instrument patch settings addressed via bank+program numbers) for the same channel and bus. Maybe it's your trouble. Try using a distinct MIDI channels for each of those tracks/fluidsynth-dssi instances.

Tell me more.

thanks, that solves the

thanks, assigning a different channel for each track solves the problem. But I'm confused: the two plugins were assigned each to its own track, how is it they can incluence each other? I think it's not clear to me how midi routing works in qtractor, if one uses dssi plugins on midi tracks

Re: fluidsynth dssi problems

nothing to do with MIDI routing but to way Qtractor does MIDI track instrument patch mapping (bank+program to respective patch/preset names).

cheers
