I am trying create a very simple M4L midi device in order to turn on/off the LED feedback at button pressure in the User1 page in my Novation Launchpad.
The problem is: if I try to do it in Max alone (I mean, with Ableton Live closed), it’s super easy:
I just create a "midiin Launchpad" object that goes directly into a "midiout Launchpad" object, and I get immediately a LED feedback.
Unfortunately, if I open this patch inside Ableton Live, nothing happens, the buttons remain off.
I also tried to create an abbreviation, from Max menu → Options → MIDI Setup.
I called "Launchpad" in and out ports as "a"…
Once again, in Max itself it works immediately, but not when I put the patch inside Ableton Live.
Thank you very much!
Do not use the "Launchpad" attribute when creating midiiin and midiout objects in Max4Live… just midiin or midiout .
Live can only see the midi stream routed to the channels max4Live plug by Live:
you select the midi in and out in the Ableton Live MIDI channel.
& You must be sure the Launchpad is "seen" by Live, by selecting it for input and output in the Live Midi preferences.
hope that helps…
Or use user 2 mode of the launchpad, and then utilise the control_surface method to light etc.
