Hey Jazi,
Hmm.. Hard to tell. There were a lot of changes for 2.0 and since
it is not feature-complete yet, it is not properly tested on all
platforms either.
Could you increase the log level [1]? Maybe this will give us some
extra clues. Failing to connect to the audio interface itself
should not be the cause of the crash. Do these [::connect] errors
occur in Hydrogen 1.2.X as well?
Also, does the crash happen during startup or while you are
performing a specific user interaction? Is Hydrogen already
receiving MIDI messages during startup? If so, could you try without.
I'll check using my Windows laptop too. But I do attend a course
this week and may not have time to do so till Sunday/Monday.
Thanks for testing and sorry about the trouble. All the best,
Phil

Hi Phil ,
Great to hear about the Midi Clock.
Unfortunately Hydrogen-2.0.0-pre-alpha-8b2e673ba-win64.exe
installation on Windows 10
would not start - here is the contents of the logfile:
(E) [Filesystem::drumkit_list] drumkit [Jazz Funk Kit] is not

(E) [::void handleFatalSignal(int)] Fatal signal 11
Stop logger
(I installed it into a different folder from existing Hydrogen
v1.2.6 Installation)
Tried 3 different audio outputs and they all had the same
error "Can't use device 'Speakers (xxxx)', using default stream"
Any idea what I could do to get it to run withour Error?
Kind Regards

Hey Jazi,
I have a first draft of a prototype featuring a MIDI clock
implementation (AppImage [1], macOS [2], Windows exe [3]).
There is most probably still some work to do in order to
make the synchronization real tight. Hydrogen is not yet
designed to offer real time support of MIDI messages [4].
Could you check how synchronization is handled at your
end? I managed to borrow a synth supporting MIDI clock
messages but my setup is far from ideal.
Please note that this is part of a development code for
version 2.0. When using the application linked in [1]-[3]
you can only open your drumkits and those songs touched
with a more or less recent version of Hydrogen from the
1.2.X release line. So, better make a backup of the
`.hydrogen` folder beforehand. See [5] for details.
All the best,
Phil

Have subscribed to 1644 - this will be a great
addition and allow
using Hydrogen in Sync with DAWs and other Apps.
VST would really only be needed for Apps that have no
Midi Clock
sync , where Hydrogen VST version would follow App's
Transport.

Hey,
MIDI Clock is already on the shortlist for the 2.0
release (see [1]). If you already have a Github
account, you can subscribe to the ticket and will
receive notifications when its state does change.
VST/LV2 plugin, however, is not planned yet.
Actually, I'm a bit at a loss in this regard.
Should the whole application as is be converted
into a plugin? Or rather just the sequencer while
both the pattern and song editor should be omitted?
Beta testing would be great! The main branch
contains the latest version and I could provide
you with an executable if you tell me which OS you
are working on.
All the best,
Phil

Hi ,
Thank you for creating Hydrogen.
I am interested on how you are progressing
with Midi Clock ?
Also wonder if you will be creating a Hydrogen
VST3 Plugin ?
I am available to Beta Test your latest versions.
Kind Regards
