Zynaddsubfx as a plugin

Hello, I didn’t realise there were time limits for topics on this forum, so I’m reopening the same topic with a video that has sound.
I can open Zyn and get sound when I use it with my keyboard.
When I want to use Zyn as a plugin, I can’t. Thank you in advance for your help.

Well, on your track you can see you start with the fader, then you insert MIDI (the red connector) in your EQ and from there over to your synth, so my first guess would be that you actually need to set up the track properly. Synths usually go first, to produce the sound. The you use EQ to shape the sound, and then the fader to set loudness level in the mix.
Same thing with your first track. Usually you want the fader to be the end of the process chain. You may see that in the other tracks everything is set up correctly.
To re-arrange these elements, simply drag and drop them into position. The wiring should be done on it’s own.

Used to run into a lot of Zyn problems like this and it was usually down to MIDI channels so just in case it helps…

Zyn is designed for multiple MIDI channels, and you can load different patches at the same time, into different ‘Parts’ with each ‘Part’ on a different MIDI channel. So maybe you’re sending MIDI notes on a channel for a ‘Part’ that is not activated

Look in the Zyn GUI Mixer settings and try changing the MIDI channel set to ‘Part 1’, trying different MIDI channels until it starts making sound. (Presuming the patch you want is on ‘Part 1’)

You could also try turning on all the different ‘Parts’ and see if any of them start making sounds.

Thanks but it doesn’t work . I put Zyn > EQ> fader at the end but no signal. I recorded my work, closed it and re-opened it but still no signal.

Where is the Zyn GUI mixer ? and what is the part 1 ? Maybe can you sen me a picture. Thanks by advance

That is the channel routing options. You should be able to double click the zynn module on the rack and a GUI window should open up. I think what e_r meant was that you need to set that up inside zynn itself, navigating through it’s inner tab to where you can set the MIDI channel incoming.

Looking at the video, I don’t understand why your Zynn looks like that. Mine looks like this:

You can see there is a mixer tab there. Maybe you disabled the GUI somehow?

I saw in the video that you are using the lv2 version of zynaddsubFX, did you try with the VST version? Sometimes that help me to make a plugin work.

I had this GUI version before but on my debian it has dissapeared. Maybe you are on a OS or a Windows?

I have a debian . How can I get the VST version ? When I visit Synaptic and I ask fot VST, man says I have already zyn VST . But when I scan the plug I just see zyn-lv2.

did you try rescanning or making sure that in the folders where ardour search for plugins the vst folder is also included?
in my linux mint 21.3 they are in /usr/lib/vst , but they could also be in /lib/vst

maybe did you just right clicked the ZynAddSubbFX plugin button and then clicked on “Edit with generic controls”? if that is the case, try right clicking again and press “edit” that should bring the GUI again.

It shouldn’t be an OS issue, so I would certainly try what Kemasolar is suggesting.

I have added the path to vst and have choosen the vst version of zyn but how can I have all the sound of this synth?

Maybe you are installing a particular version that has no GUI? I Don’t know much about Zynn, but I understand this GUI implementation I have was created on top of the synth itself.

where did you downloaded it? is it the 3.0.5 version?

I use 3.0.5 from Librazik4 ( debian 11 with a librazik 's " layer" )

https://librazik.org/

I would also try asking them, since they are francophones and are offering you the plugin. One further step you can take to solve your problem is troubleshoot all versions of Zynn. By this I mean, do you have a GUI using stand alone? Vst? LV2? If you have no GUI whatsoever then it’s clearly a Zynn issue, so I would probably re download from another source or something.
