MIDI note events not played

[manuvi]

Hydrogen version * : [1.2.0-beta1][1.2.0]
Operating system + version : Debian sid
Audio driver + version : jack 1.9.21 with alsa midi seq

---

Connecting a midi device to MIDI input port, activity led blinks when events are played but no instrument (sound) is played.
This happens both in instrument or drumkit mode, all the events seems to be muted.
If i click manually on the single instrument, sound is played on jack output.
From log, note seems to be correctly handled, if I play a note outside drumkit extension, warning log appears.
No others messages (any kind of warning) are present in log file.

With version 1.1.1, same setup but instruments (and then sound) is played on input event from MIDI.

Hey @manuvi ,

Hmm. That's odd. I can't reproduce it.

You are using ALSA MIDI as MIDI driver? Do the inputs show up in the mixer?

Also, could you increase the verbosity level to Info and append a log file?

I have the same issue. Hydrogen 1.2.0-beta. Ubuntu 23.04 which uses Pipewire. Using ALSA or JACK-MIDI makes no difference. Also setting the midi input device (tested eDrums and midi-keyboard) via Preferences and/or via Patchance makes no difference.

Edit: Easy to reproduce by just booting to Live version of Ubuntu Studio 23.04.

Hi @sirsipe ,

Could you provide a log file generated while the error occurs? In addition, would it be possible for you to check whether this issue does occur too when using plain JACK instead of JACK via PipeWire (there have been some issues with the latter lately)?

Edit: Easy to reproduce by just booting to Live version of Ubuntu Studio 23.04.

Good to know. I will try in a couple of days.

Having Hydrogen pre-configured for JACK and Midi for ALSA, without configuring MIDI input in Preferences, and option to use midi output note as input note set:

1. Open Hydrogen -> loads GMRockKit which has Kick assigned for Midi Note 36.
2. Let log level to Debug
3. Used Carla to map my Midi keyboard to Hydrogen
4. Pressed C on midi keyboard (Mini note 36) -> Hydrogen registers the midi input, but doesn't play the kick.
5. Opened the log and saved it; it's attached.

Ubuntu Studio 23.04 has an option to switch away from Pipewire to Jack, which is actually recommended for pro-audio usage. (https://ubuntustudio.org/switching-audio-setup/). I tested this and then quickly tested Hydrogen but it didn't make any difference.

I downgraded to Hydrogen 1.1.1 from Ubuntu 22.10 repos (in Ubuntu 23.04) and it worked immediately. I'm next trying to re-enable pipewire and see if Hydrogen still works with that.

EDIT: Confirmed Hydrogen 1.1.1 works with Pipewire in Ubuntu 23.04.
EDIT2: Confirmed upgrading back to Hydrogen 1.2.0~beta1 breaks the midi input playback.

Thanks a lot for your research!

I was able to reproduce it by throwing away my $HOME/.hydrogen/hydrogen.conf file. It's indeed an upgrade error.

As a work around you can disable Preferences > MIDI System > "Discard MIDI messages after action has been triggered"

Hey @sirsipe ,

Could you check whether #1768 fixes this issue at your end?

[sirsipe]

I can confirm both the workaround and that #1768 fixes the issue.

Thank you and great work, @theGreatWhiteShark!

Closed with #1768
