After latest update, Oram refuses to do quite a few things, such as (trying to) add a chain

Software

After trying to add a chain, or, as in the log below, selecting a chain and then another one, nothing seems to work anymore.

This happened after an update to oram (which I did as I wanted to check out latest sooperlooper improvements).

Hi @niels

Oram is 64-bit only so there is no direct update route. You need to flash a new image to a uSD card.

@jofemodo we should change stable to remove the ability to update to Oram.

Hi @niels !

Update again, please :wink:

Regards,

@jofemodo thanks, but this did not work. I experimented some more, and as far as adding chains go, any type of chain does work, except for Audio or MIDI+Audio chains.

@riban, it is an oram image which I burned and updated (a few times already). Sorry for the confusing wording I chose.

Here’s the log for booting up Zynthian into the mixer, bold-pressing to get to the menu, and adding an Audio chain:

Push the “search for engines” button in webconf, please.

@jofemodo I hit the button, waited for it to finish, then rebooted. Same issue.

Could this duplicate name be the cause of my problem?

9

This may be related. You could try disabling it and seeing if there is any improvement.

@jofemodo we should probably remove the LV2 instance of SooperLooper. I don’t think it gives us any benefit and is likely to lead to further confusion. Probably want to do similar with others like Aeolus, Fluidsynth, setBFree, Pianoteq, etc.

Disabling both of them lets me add Audio chains again.

What steps would I need to perform to get SooperLooper with the special interface working again?

11

Duplicated names shouldn’t be a problem. Each engine have a unique ID assigned, that is used internally for all management.

Try enabling again, please.

Hi @jofemodo. Re-enabling SooperLooper/Looper gives me the same problem again.

13

Please update your zynthian and push “Search for engines” button again.
If not, send this file:

/zynthian/config/engines_config.json

and i will try to figure what is your problem.

Same story.

Thanks @niels!

Your DB file helped me to find the issue: a wrongly assigned category in the engine DB regeneration code. Please update and test.

Thanks @jofemodo . After the update and search for engines, adding audio chains works again!

But now adding Synth Chains failed. KeyError Modeler

18

Ups! I will try to fix it tomorrow. Until then, you could solve it by running this from terminal:

cd /zythian/zynthian-ui/zyngine
./zynthian_lv2.py engines

Then reboot.

That’s my opinion too.

I will remove duplicated engines that could cause confusion.
