Problem with loadin complex snapshots

multim · July 17, 2021, 7:21am

Hi,
I’ve tried to prepare some 10 layer snapshot using multiple Linux Sampler and Fluid Synth instuments. Also I’ve applied some audio FX for guitar and noise maker. It seems that everything works fine during inital configuration but after I reload snapshot two layers go mute and audio effects doesn’t work.
Should I need enable some setting to make it store/load completely?

Here is my snapshot (enabled Guitarix plugin, other than that default zynth configuration)

I will take a look and try to figure/solve the problems

Hi @jofemodo,
did you manage to look into this issue?

This occurs every time for similiar scenario when I use TAL reverb and Gain FXs (one, serial for each channel) and multiple engines.
I’m sure it is connected to audio fx chain restoring or saving, because this happens for different engines with different setups.
In logs I can see Xruns when fx plugins are resetting, but no errors or warnings during loading.
When I look into layer options, audio output, then no output is set for corrupted layers.

Sorry @multim !!

I’ve been very busy with the issue tracker list and developing new & exciting code
Please, could you open an issue on our tracking system?

It’s the best chance to get the issue solved in the near term. Please, copy all details from this thread, and include some snapshots for reproducing the error.

Thanks!

Bug

**Describe the bug** I’ve tried to prepare some 10 layer snapshot using multipl…e Linux Sampler and Fluid Synth instuments. Also I’ve applied some audio FX for guitar and noise maker. It seems that everything works fine during inital configuration but after I reload snapshot two layers go mute and audio effects doesn’t work. This occurs every time for similiar scenario when I use TAL reverb and Gain FXs (one, serial for each channel) and multiple engines. I’m sure it is connected to audio fx chain restoring or saving, because this happens for different engines with different setups. In logs I can see Xruns when fx plugins are resetting, but no errors or warnings during loading. When I look into layer options, audio output, then no output is set for corrupted layers. **To Reproduce** (At least) on my device: 1. Configure new snapshot with at least few layers (SFZ player, SF2 player and other). Add at least one reverb (eg. TAL II) and Gain audio fx-es for each layer. 2. Store snapshot with this configuration. 3. All works well until device is not restarted. 4. Restart Zynthian. 5. Some audio chains do not load properly, some audio routes are "unchecked" and layers do not produce the sound. On any other devices: 1. Load snaphot 05-Gig Basic.zss or 007-LS;SFZ;Pianos;SalamanderGrandPianoV3.zss 2. Some audio chains do not load properly, some audio routes are "unchecked" and layers do not produce the sound. In first snaphot affected layers are 1st Fluid Synth (Full Grand) and 7th Noize Mak3r In second that are: **Expected behavior** Layers and audio chains should be restored to the same state, that they were configured. **Setup:** - SD-image: 2021-09-25-zynthianos-stable - Hardware Config: Zynthian Kit v4.3 (HifiBerry DAC+ ADC PRO - Software Version: zyncoder: stable (7c09738) zynthian-ui: stable (478b6ab) zynthian-sys: stable (e33fd3a) zynthian-data: stable (006a071) zynthian-webconf: stable (39b61bb) Snapshots that are not loaded correctly: [corrupted-snapshots.zip](https://github.com/zynthian/zynthian-issue-tracking/files/7653779/corrupted-snapshots.zip)
