Control Change

[arcturus2k]

Hi. Sorry for a seemingly simple question.....

I'm using this library with great results on an Adafruit Huzzah. My question is:

How do I format a MIDI controller message? I mostly need to send controller data.

Thanks in advance.

(sorry if this is not the correct place to post this question. I could not find another way)

In this library you do not format your own messages, all MIDI messages come pre-formatted in the API. All MIDI messages should be supported.

Sending a Control Change message require 3 parameters, 2 related to Control Change (controlNumber and controlValue), the 3 parameters the midi channel. (similar if you receive them)

More information on Control Change here: https://www.midi.org/specifications/item/table-3-control-change-messages-data-bytes-2

@arcturus2k if the above answered your question, pls close the comment. Thanks!

Maybe I didn’t ask the correct question. I understand the construction of a MIDI controller message, but how do I call the actual function in your code? I’m looking for the actual function as I know what to pass to the function.

OK. Load the Esp8266_NoteOnOffEverySec example, and replace AppleMIDI.noteOn(note, velocity, channel); with AppleMIDI.controlChange(1,2); replace 1,2 with the controlNumber and controlValue of your choice

In general: look in src/AppleMidi.h, at lineNr 183 for the MIDI commands that are available.

Thanks. That is exactly what I need. I looked through several .h files but did not find the section you referenced - I need to look harder. Thanks again for the help and the pointer to the code. I really appreciate it!

Thanks. One last question. I can only get a single controller to send at a time. The first cc I address inline in code. Am I missing something? Is there a way to send multiple CCs using this library?

Thanks again.

Hi Steve J

I read your question multiple times, but I'm not sure if I understand (I do not know what your knowledge level of MIDI, programming or Arduino is).

Is this what you want to do?

AppleMIDI.controlChange(1,2);
AppleMIDI.controlChange(1,2);

@arcturus2k are you happy with answer? then please close this issue
