user.py: _send_midi denied

Hi,

the user.py file is a great chance to do more efficient script code. I´ve done a few nice things last week, now I´m frustrated: I call the ” self._send_midi() ” command for sysex in a function inside the user.py file. But i get an error-log kind´a:

..\..\..\output\Live\win_64_static\Release\python-bundle\MIDI Remote Scripts\_Framework\ControlSurface.py”, line 690, in _do_send_midi

2024-06-15T12:52:47.868496: error: RemoteScriptError: AttributeError: ‘css_slmkiiidevice’ object has no attribute ‘send_midi’

Does anybody know how I can use it inside a user.py function?

Regards

Dieter

Hi,

I also was stumped by this problem a while back and today I finally found (some kind of) a solution.

The _send_midi method is part of the ControlSurface module. Looking inside the module’s code I found that it then sends the bytes to the method _do_send_midi, which in turn sends the bytes to self._c_instance.send_midi (as you can see in the picture below):

Here’s where I think the problem happens (but I’m not entirely sure because I don’t fully understand how c_instance works):

_do_send_midi doesn’t send the bytes (AKA the SysEx message) to the c_instance of the user.py file; instead, it sends the bytes to the c_instance of the Remotify script that has imported the user.py file. Apparantly, these c_instances behave independently or something.

I’m taking a guess here but I think the c_instance creates a send_midi method whenever the _send_midi is called in its respective script. In other words, when calling _send_midi inside the user.py file, the c_instance of the user.py file gets a send_midi method, but the c_instance of the Remotify script that imports that user.py file doesn’t get a send_midi method.

How to circumvent this problem:

Create your own send_midi method inside the class of the Remotify script, like this:

def send_midi(self, msg):
  self._send_midi(msg)

This way the _send_midi of the c_instance inside the Remotify script is called too.

The problem with this solution:

Whenever you will update your Remotify script, you’ll have to re-enter this piece of code.

I’ll send a feature request on the forum in the hope that the devs will implement some similar code to be added to each iteration of the script.
