View Full Version : syncing Mobius although synmode is "off"

Hi guys,

I just found out, how to sync Mobius within Bidule, without needing any of
Mobius syncmodes.

This is important for me, because there is some buggy behaviour when
Mobius is in syncmode. You can read that in the "strange Multiply
behaviour"-threat, I started in the General section of this forum.

I have used a "Tap to Tempo"-Group, i´ve found in the Bidule forum and
tweaked it, so that it features the possibility to define a minimum bpm value,
just like Mobuis does.

All you need to do is to link the record function and the tap function by
making them using the same midi event for trigger.

I´ve tested it by syncing mobius with a drumcomputer and after two hours,
there was no notable sync drift! So, it surprises me too, but it really works
great!

If anybody wants to have this Bidule-Group, let me know and I will send it to
you, or upload it somewhere...

Regards,
Frank

I'm glad you found a workaround, but your experience is unusual.

Unless there is coordination between the application looping the audio
and the application generating the MIDI clock they will eventually go out of sync. It may take awhile but it will happen.

Mobius sync out works a little like what Bidule is doing. After recording
the loop it calculates the MIDI tempo then launches a little thread that
does nothing but send MIDI clocks and is unaware of what the looper is doing.
What is different is that the looper keeps watching where the MIDI clock
is and if it notices any drift it will correct. Due to floating point rounding
some tempos are more stable than others. I typically get a drift correction
after 10 minutes or so. I've never watched it for an hour but it is possible
that if everything aligns just right it would remain stable for longer times.

BTW, I fixed the problem with multiply, it will be released this weekend.
