next release : any MIDI clock improvement ?

[La Tenaille]

Hi,
I'm planning to rebuild a huge workspace because of MIDI in clock issue, but if there are changes in HH v2 I can wait.
Is it planned ?
Thanks

Can I have more details about your issues?

One issue is that HH sends tempo but not song location (bar/beat). Query #58 is related to this. This thread has some background:

Note the thread listed also refers to bug #36 as being open & related to MIDI clock. I can't read bug #36.

My trouble is an old issue about Mobius VST in MIDI master mode. The sync shifts slowly in Usine.
We are a few on this forum to worry about it. The trouble doesn't seem to happen on other popular hosts.

Hi la tenaille & shawnb!

moonSafari's clock patch in the add-on section has been my clock fix for this problem.

I use HollyHock to sync back and forth between Sonar and several other applications. So about 2-3 minutes in I tend to have drift of the clock. His add-on has been very helpful in resolving this for me, as he uses a based calculation of tempo to handle start and stop, and the clocking.

I modified this script further with a "Fudge-offset" factor to adjust my clocking to match and sync my metronomes. It has worked wonders for me and I am now in synch consistently.

Sometime soon, I will put my personalized add-on in. However you should checkout how moonsafari is handling this and might help out.

I agree though, there is a drift problem in the MIDI sync

How can we use this patch with möbius ?

That is very strange you are having drift problems with VST, I use Arturia Spark and do not seem to have drift issues with this VST internally via VST Host.

So I have not explored much with Mobius, however I do see that there are various synchronization options, Looks like not only can you sync by VST host, but by MIDI. If you are having transport problems with the VST set to Host, why not try the MIDI sync option.

You could use LoopMidi->Send Sync out one rack, create an Input that Receives Midi Sync and then pump that to the MIDI input of the Mobius VST. I don't use Mobius so maybe even using the MIDI sync of HollyHock, rather than the VST host sync might yield some result.

Just some suggestion, I have battled some sync drift issues in other ways not specifically to Mobius so I do understand there is an issue going on.

@la tenaille:
For info the Möbius issue, is absolutely not connected to MIDI clock implementation in Usine

[La Tenaille]

Thanks Olivier. Any clue, link, anything that could help solve my problem ?

[senso]

As I understand (I'm not fluent with Mobius), this VST can receive or send Midi Clock which is not really in the specification of VST.
Normally, for synchronization, VST's use a set of values called VSTTimeInfo which are much precise than any Midi Clock.

Also, I did a quick test and Mobius 2.4 seems to work as expected, or maybe I don't understand your pb?

Did you try to contact Mobius developers ?

[La Tenaille]

ok, so after investigations it seems the timing clock drift is a known Mobius issue. A pity Mobius is getting old and Jeff seems too busy to upgrade it (64 bits, feedback...).

good news for me but not for you....
