I want to make a little patch to filter out the start and stop messages from Ableton's midi clock - but keep the tick, for a specific - track, if not track then a specific midi control surface in Ableton - to be used with my Minilogue. The sequencer starts every time Live plays - I don't want that, but I do want to keep the lfo and arp in sync.

In Max, or if rt messages passed through tracks, this would be as simple as rtin -> route 250 252 248 -> optional toggle to turn this feature on/off etc.

However to do this in Max4Live I have to access the API and use live_path control_surface..... that's about as far as I got - I'm struggling with the LOM document and have tried using a getpath control_surface N message into the live_path object with no luck.

Can anyone please advise? - or show by example? - it would be a nice easy example to serve as an introduction to using Live's API for me.

I'm hoping the path does not have to be absolute in case my midi in/out devices change.

What I'd like to be able to do is display them in a umenu so I know which midi device/surface I will be filtering - just like you can in Max.

fairly certain I have confused control_surfaces in the API with midi ports. So of course using a control_surfaces path is only return id 0 for me.

Is it even possible for Max4Live to be able to modify Ableton's real time midi clock output?

Every time I try to use an object that deals with midi ports in a track it only makes references to other devices in the track rather than midi clock - which I'm guessing is global for either the application or at least each midi port or device.

Am I going to have to do this another way - such as route midi to and from Max/MSP and then route that to my synth?

For unrestricted midi I/O in M4L you could use an external object, for example

For some reason I thought Ableton had fixed NRPNs and SYSEX etc in tracks.

I thought this would be simple - I just wanna play keyboard :)

Thanks!   I'll add them and take a look.


Hmmmm, Maybe this is a silly question, but am I supposed to install/add RtMidi somewhere on my Mac?

I've added the externals and can't seem to get any messages in or out of them - the only response I get is a 1 out of the port status outlet.

I've had a little look at the RtMidi page on github but have not found any instructions on how to add it to my Mac.

I've added the externals  and can't seem to get any messages in or out of them - the only response I get is a 1 out of the port status outlet.

Externals must be in a max search path (listed in the menu 'Options>File Preferences').

Yes I have that sorted - I can add the objects in a patcher and access their help files and all, however I cannot seem to get any midi going in or out of either of them (I'm testing this at work without an interface so I am using to/from Max 1 and 2 ports).

imp.midiinfo - correctly populates a menu when given a bang - I just don't seem to get anything from the imp.midiin or imp.midout other than a 1 output from the port status outlet.

David's site says - "MIDI support in these externals is implemented using RtMidi, a very useful C++ cross-platform MIDI library."

I'm wondering if I have to manually add RtMidi to my Mac somehow, or is he saying that he has used this midi library inside his external, I'm unsure.

No, you don't have to install anything else.

Note however that in the thread I've linked above someone has mentioned that imp.midiout doesn't work as the help file says, ie. notes must not be send as sequence of bytes [144, 60, 80] but as a list [144 60 80].
