Dear PD community, could somebody explain MIDI CC messaging to Volca sample or similar . I use M-audio midi-usb converter. The patch with ctlout seems to be working. The led lights up on the M- audio device, but Volca is not reacting. It is hard to test the MIDI channels because it has only MIDI-in connection and it is hard (at least for me) to understand the official MIDI Implementation Chart (https://cdn.korg.com/us/support/download/files/9bdc4997e44b7e96e771f612e06a90e5.pdf?response-content-disposition=inline%3Bfilename*%3DUTF-8''volca_sample_MIDIChart_E.pdf&response-content-type=application%2Fpdf%3B).

There are some tutorials and it seems to be working here: http://filipe-teixeira.com/electronic-music/volca-resources/volca-sample-tutorial-5-midi-and-external-automation/

@aurimas_g This........

should control the level (control cc message 7) on midi channel 1.
The slider has output 0 to 127.
In the first link you posted there is a note that "*1: Received when global parameter MIDI RX ShortMessage is set to ON."

That must be a setting within "Volka" I think.
Probably here...... http://filipe-teixeira.com/electronic-music/volca-resources/volca-sample-tutorial-7/

Thank you Whale-av for input.
I got it working on Volca sample but now I have to implement the knowledge on other volca's.
I was thinking ahead how to send midi signal from pd to different M-Audio midi outputs.

@aurimas_g
Pd midi out channels 1-16 go to the first midi out selected in the Pd "Media" "MIDI settings" window.
Pd midi out channels 17-32 go to to the second selected device on channels 1-16.
Pd midi out channels 18-48 go to the 3rd selected device on channels 1-16.
............etc.
If you can select each midi out separately you are in luck, but maybe 1-32 will go to out sockets 1 and 2 automatically on the M-Audio device anyway?
In Linux I think you can set midi ports for [midiout] ....... and [midiin]
