Max For Live multiple output

October 19, 2010 | 7:58 am

Good morning to everybody,
I’m developing a multichannel plug-in for sound spatialization.
Working on it I reliazed that there is no possibility to use the ‘plugout~’ object with more than two outputs although you can specify more outputs in the argument.

Using different kind of track in Ableton or ‘dac~’ instead of ‘plugout~’ does not seem to work equally…

Is there any possibility to implement multiple out?!
Thanks to everybory

Nope. It’s a limitation imposed by Live.

October 19, 2010 | 10:29 am

This is a very bad news…
So it’salso impossible doing something like this:

Thanks for you availability!

Good point.
In fact, Live recognizes the individual output channels of a multi-channel plugin. So strictly speaking, the limitation is caused by incomplete integration of M4L devices, namely that devices with multi-channel output can’t be built resp. are not recognized as such from Live. But this shouldn’t be too difficult to implement, so we may expect some improvement in future updates..

The limitation comes from Live itself. There are only stereo tracks in Live. Even boring 5.1 isn’t possible.
But I found a workaround – have a look at it. I made this some time ago and haven’t touched it for a while, let me know if it works for you:

I uses a rack to obtain multiple physical outputs. The sound is not going through the Master track, but the master volume will control the volume accordingly…

As I have a running Live again, I could tweak it if necessary…

Very nice solution,

So it could be possible to turn this way of spatialize in live into ambisonnic technology, including ambiencode~ and ambidecode~ objects inside each patchers, using each time only two outputs of ambidecode, and controling it via the system of forward/receive with an ambimonitor object inside the main patch…

isn’t it?

October 20, 2010 | 10:59 am

In my solution, I simply forward control data for gains, which I calculate in one patch. I guess that for ambisonics you probably need to duplicate the same patch with multiple ambiencode~/ambidecode~ objects which only feed different outputs to the device output. Its not very effective, but should work. And please nag Ableton to finally allow universal tracks. Not only for more audio in/outputs…
I know exactly how it should look like, but nobody would listen to me – revolutions are worrisome, I guess…;-)

what do you think about plugsend~ and plugreceive~ ?

October 23, 2010 | 3:55 pm

plugsend~ and plugreceive~ are not officially supported in M4L.

It seems to work somehow, but induces unpredictable latency.

@ Stefan : I think St.pace is broken under Live 8.2.5 (m4l 5.1.9) … I’ve been using it regularly. Recently tried to put it into a new session but without any luck … I can still pan on 1/2 but it’s not going to 3/4 etc.

I’m on OSX Lion but noticed it’s also broken on Live 8.2.2 Snow Leopard … got it working on 8.2 though (don’t know which m4l version) under SL

Would be nice if you could look into it … If you’d be able to find some spare time. I really love this tool!!

Well, more than 2 years later and this is still a current problem.

Is there any more news about multiple outputs in ableton?
Like a multiple output m4l vst?
Or even better different multiple outputs in 1 channel. Like a 8 output channel, or a n-output channel.
Like reaper does it, is very nice. But I guess that’s up to ableton.

But the multiple output m4l device must be doable right?

Thanks for any answers (especially from cycling74 ;) )

I also interested in and support the issue of implementing multichannel out.

October 29, 2013 | 2:35 pm

I have done 8 channel outs in Live with M4L before.
You have to use sends, and you can discretely assign those to physical outs, bypassing the master. You have to set up a patch that controls the audio being sent to each output (by output I mean send), using live.remote’s that are tied to the track sends. I have a patch at home I could throw you guys if anyone’s interested.
It’s a hacky approach but it works really well.

October 29, 2013 | 11:25 pm

that´s only a workaround……but not so powerful, if every channel has it´s own 8 outputs (especially for spatialization).

October 30, 2013 | 10:08 am

Well it’s Live, so every solution will be a workaround. Use Max standalone if you don’t want to have to "workaround".

What do you mean by "not so powerful"? What is lacking in this particular solution?

October 30, 2013 | 10:36 am

independent spatialization on different audio tracks with amplitude panning f.e.

October 30, 2013 | 11:14 am

This solution CAN do that.

October 30, 2013 | 11:18 am

The "powerful" solution I chose for the moment it to MIDI remote control Max from Max4Live. I send audio from Live to Max using "loopback" fonction on RME interfaces.

October 30, 2013 | 12:51 pm

ok, can I have a look in your setup (patch) ?
(I already use 11 track sends for FX…so it becomes confusing with additional 8 sends for spatialization)

October 30, 2013 | 2:37 pm

If you’re using sends for effects, then this solution wouldn’t be able to spatialize the processes as far as I know….

That could be a potential deal breaker.

October 30, 2013 | 3:36 pm

The maximum of sends is 12…

October 30, 2013 | 11:54 pm

@ chapelier fou

12 sends, good to know.
Never saw the feature of loopback in rme-interfaces and "accidentally" I use MetricHalo.

for the record, Kontakt VST 16ch *can* send audio to other channels from one Live channel. Here’s how :

(edit : my point is that if Kontakt can do it, then it should be possible from Max too. The method discussed is not as versatile as a max send~/receive~ pair though, but it could be some sort of temporary workaround)

November 11, 2013 | 8:36 am

Did you ever use [plugsend~] [plugreceive~]?

Even if Max documentation says: "The use of the plugsend~ and plugreceive~ objects to pass audio between Max for Live devices is not supported." it seams to work.

I am trying them at the moment. With my setup I get a steady 46ms latency (2048 samples) between [plugsend~] and [plugreceive~], and I have not noticed any problem.

Well, it is not perfect, as I get 1ms latency between [send~] and [receive~].

Here my latency test devices:

This is really something that needs to be done.
is there any official statement wether or not this is going to happen anytime soon?

March 28, 2014 | 6:18 am

Totally agree with you Dibek.
I’d like to know as well.

March 30, 2014 | 7:34 am

This is a question to ask Ableton rather than Cycling ’74.
