Sync multiple mubu.concat~?

#1

This is a bit related to my previous big post yesterday : Some questions about playing controls, polyphony and more

If we could use multiple mubu.concat~ with the same set of data (I mean data from segmentation analysis of a same corpus. which would required to duplicate all from control to segment selection and triggering parts… for getting n cursors), how could we sync these mubu.concat~ ??

Actually, I know mubu.concat~ is triggered by message markerindex messages, depending on trigger mode.

By sync I mean, there is “a kind of period/rate in beat mode”. I know it depends on the period parameter of mubu.concat~ and in some tuto patches this one is goind back to the triggering system parts. but how could I use beat triggering mode with multiple mubu.concat~ ?

Right on time! concat’s period is sub-sample precise, but hard to sync to other things (you can bang to reset all periods. See also aligned playing).

But I’m just about to generalise the transport-synced metronome from skatart as camu.syncmetro (https://github.com/ircam-ismm/catart-mubu/blob/wip-syncmetro/patchers/lib/camu.syncmetro.maxpat), it works, except one last detail on change of period.

In future developments, mubu.concat could sync itself to the Max transport by giving periods in note syntax, like 16n, 0.2.160.

Hey @schwarz, thank you for the amazing work on Catart, been following it for over 15 years, it’s so great to see it evolve and get better!

Slightly different question but related to this topic - is there a way to get absolute start time of a buffer playback position before/after it hits mubu.concat~? I would like to sync the selection to corresponding video buffers and I am wondering if there’s a way to do that?

Hi, concat outputs marker and buffer index at right outlet, you can query the segment time with gettime to mubu.track.

#6

Just wondering if there has been any development of synchronisation for mubu.concat~, especially as described with transport sync/note values - I am deciding whether or not to make my own granulator to work with mubu data.

Hi, the transport sync is not yet directly integrated with mubu.concat, but have a look at the sync metronome in the 1.7.1 prerelease. It is the way sync works in many M4L devices, and at 64 samples vector size it is tight.

Thank you - I will have a look at the prerelease. For now, just quantising my gestures in ‘bow’ or ‘fence’ mode works for many situations.

I have also looked at ‘aligned’ mode, though for me it would be more intuitive to somehow trigger a grain at its current position using a signal - so that the trigger was separate from the position.

For that, set mubu.concat to play 0, autotrigger 0 and send a bang to trigger. Also check delay to schedule the trigger within a signal vector.

Excellent - that makes sense, this is actually a very flexible approach for my purposes. Could use the [line] object for ramped tempo changes, etc. Cool.
