I want to create a m4l device which records 1 bar of audio, passes this to node.script and later receives an answer from node script. 

I want to analyse the audio in node.js and then modulate the VST settings based on the analysis.

I went so far through the basic tutorial for creating a m4n app:

- store the audio in a buffer ( I guess objects are: record + buffer)

Is this directly possible? I found this thread from 2018:

https://cycling74.com/forums/audio-stream-to-max-with-node-js

Alternatively, I could watch a folder for new files in node.js, then I would need to save the buffer to disk.

- (process the audio in my node.js script)

I could need some guidance on which M4L objects I need to use, then I can research on my own how to use them. Into which M4L object should I read in/watch further tutorials? What would be the basic layout for this process, am I right with the above steps. Is this possible with one M4l device or would I need to split it up e.g., one M4L audio device which records and saves on play and one M4L midi device which controls the VST?

For the second case (one midi patch for controlling, one audio patch for recording) I created an example patch, but I'm not even sure how to auto record 1bar to a specified file:

- store the audio in a buffer ( I guess objects are: record + buffer)
- stop recording after 1 bar (?)
- sending the buffer to node.script

- send message from node.js to m4L (?)
- control VST param (?)
