MTC divider/multiplier with Max

if i'm not mistaking you'll need to go *out of* live to so this.
live doesn't run it's clock(ing) through your midi tracks but globally.
not completely sure though.

so: you'd have to route the clock out of live
-> into max (doing some divisions or recalculations)
-> and then into your synth (via max).

Hi Benz,

Yes Ableton is running the clock trough a midi track. I'm using a midi track routed trough my sound card to my synth. I would like to create a patch in max to use in Ableton.

Orignally I found this wich make me think it's possible with max.

I tried it but it won't work.!

i think i have to correct you – place a live device with a [rtin] object on a midi track and monitor (print) its output within max. you'll see that there's no clock-byte transmitted. live generally tends to filter these things (=sysex!), which often doesn't – in this case how ever does make sense. sysex is filtered on in- and output, which means you can't easily fool live and create an "own" clock to be output on your midi-track that's routed to your synth.

syncing is set up globally and not passed via midi-tracks. if the later was the case, muting a midi-track (or disabling it's input as a matter of fact) would bump your device out of sync (because no clock would be transmitted any longer).

in abletons global setting, you set your soundcard('s midi out) to send out sync. this is what your synth receives.

i have sketched the route you'll want to go in a seperate max patch. you will have to run this from within max and it *grabs* the clocking-byte from live.

if you only want to subdivide the outgoing clock (make it slower), this is a way you can achieve it. if how ever you want to multiply the clock (=make your synth run faster than your settings in live), it get's a more tricky.

haven't tested it, but it should work.

*edit: bug in the code

Yeah you're right about the sync thing thanks for the correction.

I'll try your patch (thanks for that btw) today and tell you how it's working.

Mate the clock is coming in but not coming out. I tried it internally with an other ableton but it doesn't seem to work either.

ok – some thoughts:

1) have you selected the correct midiout port (on the bottom dropdown)?

2) be sure you disable the sync output from ableton to your soundcard / synth (remember: live » settings » midi sync » uncheck "sync" button on soundcard output) otherwise you would be sending two clocks – one from max und one from live

3) reassure that your synth is actually receiving a clock. did it work with live?

4) did you set up the router (in the example patch) to actually output the divided clock signal?

lemme know! :)

1) Yes i did selected midi in from max 1 or 2 as you said
2) I disabled the sync midi in ableton pref.
3) It did worked when the sync is on
4) Yes I selected in the router to divide the clock and saw the button right after tickling.

I just tried it with some chord coming out of ableton. it's seem to change the delay and some stuff but not the BPM indicator.

mhh.. i have no real idea. i suppose it has something to do with your midi (sync) settings
and not with the patch itself.

do me a favor and send me a screenshot of your ableton midi-settings (showing all input- and outputdevices as well as which of their boxes (sync, remote...) are ticked.

your synth not updating it's bpm-display may be a device-specific thing. not all synths show the current bpm when externally synced. if however the synth *sounds* differently from when you only synced it via ableton, at least *something* is happening. (generally check the sync-up via arpeggios, delay-times etc ... chose parameters that very audibly change when you sync in order to judge wether its working or not).

I think i did everything right no?

I tried with an arpegiattor and the sync is working for sure but the selector is not "dividing" the Bpm
