[HOW-TO]workaround for sending and receiving 16MIDI channels

[igneous]

Julian it seems the link you provided doesn't work anymore.

The fact that Ableton forces M4L devices to use midichannel 1 has been a HUGE waste of my time as I tried to figure out what was wrong with my setup. I really appreciate your efforts to rectify this front.

This is not Ableton forcing M4L, this is Live only using 1 channel per track, so M4L, as a device (which means as a device within a track) is dependant of a track.

Basically, this is quite easy to code a device sending data from a channel to another. In that case, it would require send/receive from a m4l device to another m4l device in another track. The timing is not totally guarantee as the documentation is saying:



It means we can have something like send/receive busses from one device sending (let's say a m4l sequencer)
and some devices receiving each one a specific data flow from the device sending.
Each receive is its specific own track, and each one of these tracks has its [MIDI TO] set to a specific midi bus and for this bus, a midi channel.

I unfortunately don't have time to patch even a small example at the time but I guess you got the point.



Anyway,

Wait, M4L was out in 2009 ??
Damn, i'm definitely getting old.

2011.
I don't know why some time-scale collisions are occurring here

Ah ok, that's weird.

I'm struggling to create a sender device with a VST (Nora) embedded, that sends out MIDI on all 16 channels.
The corresponding receiver device(s) should receive on all activated (by filter Buttons) channels.
Live and Max are constantly crashing, so I gave up after 6h.

Any advice or hints are highly appreciated. From my understanding the structure should be far from complex, (no need for delay compensation, as featured in devices found @max4live.com)

I've found embedded VST in M4L generally problematic and had several crashes even with simple plugins, in particular when switching the device between edit and performance mode (which seems to trigger unloading and reloading the plugin).

On the other hand, send/receive between devices always worked well for me. But notice that [vst~] outputs a stream of raw MIDI bytes and merging such streams on the receiver may lead to problems not recognising the bytes which belong together. So in this case, I would pack and send the data in list format of messages like notes, CC etc.

why vst?

Nora (https://squaredheads.com) is a creative arpeggiator that can send different patterns to different MDI channels. Unfortunately Live flattens all MIDI channels.
Instead of running multiple instances of Nora VST I want to wrap it into a Max sender device and use receiver devices.

For my use case Max is only a workaround of Live's MIDI implementation
