15.0: 2 more sound related issues

#1

When I launch jack first as usual and then qSynth I get this:

With the following installed
Rosegarden
ZynaddsubFX
dssi
..and other studio stuff

and the following started in this order
qjackctl
qSynth
Rosegarden

the ZynAddsubFX dssi should show up in Rosegarden as the ZASF synth.

It doesn't, similar problem in my Artix installation as well
but not is OpenSuse or in Devuan. I don't know which "package" is
supposed to include it. I can't serach for it because only inside
Rosegarden is it identified as ZASF.

I cleared this by installing a few more AlienBob packages, not
very methodically, will specify which exactly after I repeat the
horror on my desktop

Following up in case someone might google for it:

it was installing the AlienBob Zyn package that got the ZASF dssi to show in Rosegarden:

upgradepkg --install-new zynaddsubfx-3.0.5-x86_64-1alien.txz

How come the standard ZynaddsubFX package fails?

the above 'File does not exist.' errors were fixed by loading soundfonts in qsynth prefs.

the following appear only in the file /tmp/SBo/qsynth-0.6.2/src/qsynthSetup.cpp

"fluidsynth: error: Unknown integer parameter 'audio.jack.autoconnect'"
"fluidsynth: error: Unknown integer parameter 'audio.jack.multi'"
"fluidsynth: error: Unknown integer parameter 'synth.dump'"


the following appears to show that fluidsynth 'default' does not support jack?

"fluidsynth: This build of fluidsynth supports the following audio drivers: alsa, file, oss, pulseaudio, sdl2"

I've installed fluidsynth AFTER I had earlier installed AlienBob jack2 & Audacity
