Can't play VST2 (logs attached)

General Elk Discussion
1

Hi, thanks for this great project!
I have compiled sushi for my arm64 SBC and successfully playing mda jx10 without issues.

I am trying to load Dexed that was picked up from GitHub - elk-community/dexed: DX7 FM multi plaform/multi format plugin
According to logs it starts loading and registering parameters but it fails without an obvious error message.
The only thing I see is a warning:

 [warning] [vst2] Failed to set a valid speaker arrangement

I would greatly appreciate any help!

Starting it with

root@arm-64: ./sushi -c config_files/play_vst2.json -j --log-level=debug -m4 --connect-ports

Hi thx and welcome to the forums. Could you show more of the logs? As these lines seem to indicate that the Dexed plugin is indeed loaded and added to the track

Hi Gustav,
thanks for the quick response,

It turns out I had a cc_mappings object inside the config.json (with some mappings), when I removed it, Dexed ran successfully!
The same applies to Obxd.

The other thing is I would like to have CC mappings to control VST2 from the midi keyboard.
Any thoughts why it works like that?

p.s. no issues with MDA JX10 VST3 and CC mappings.

Also, there no more logs, I provided the complete output. Please let me know if I could help with debugging

Best regards

@Gustav
Looks like the reason was an incorrect parameter name in cc_mappings. When I changed to existing parameter names (VCF Cutoff → Cutoff) it started working without failure.

So looks like a lack of logging or so :slight_smile:
Anyway, thanks for the amazing project , the issue is resolved now

Great that you got it working! But you’re absolutely right, there should def be a log warning for that kind of error. I’ll file a bug for it so that future users don’t run into the same issue. Thank you for reporting.
