Teensy 4.0 , analog VU meters for DAW

Hey everyone, first time here.
I recently came across a project that I wanted to build. It consists of a Teensy 4.0 working through MIDI - USB with a DAW plug-in ( DP meter Pro ) that allows you to send midi to the teensy ——> converts to analog and sends out to analog VU meters being triggered separately per track. So basically when this is all put together , you can build an external meter bridge. Meters are connected to the teensy PWM which is receiving midi from a DAW. I hope I got this right…..
The code is available for DL and the instructions to build the vu meters unit are available on the Blue Cat Audio site. I guess that I’m doing something wrong because I can’t get the VUs to work. I’m new to Teensy so maybe it’s a lack of knowledge on my part. If anyone has any knowledge on this or can help to guide me it would be great..

Thanks

Kosta

Are you sure the DAW plug-in actually sends out MIDA data to your Teensy?
Click to expand...
The latter you can easily check by adding Serial.begin(9600); to void setup() like so:
C++: 
void setup() {
  Serial.begin(9600);
  usbMIDI.setHandleControlChange(onCC);
  < stuff deleted >
}
and by adding some Serial.print()s to void onCC(byte channel, byte control, byte value) like so:
C++: 
void onCC(byte channel, byte control, byte value) {
  Serial.print(channel);
  Serial.print("\t");
  Serial.print(control);
  Serial.print("\t");
  Serial.println(value);
  if (channel == kMIDIChannel) {
    < stuff deleted >
    digitalToggle(LED_BUILTIN);
  }
}

On the serial monitor you will see the CC data sent out by the plug-in, alike:

(my Teensy LC-based MIDI controller sending out CC data on channel 1, control #16, values 1 & 65)

So just to say that it doesn't have to be that plug-in. If you could suggest a better or another way to do what im looking to do... Im all ears..
 
Well, you may want to elaborate on what you exactly want. Are you looking into connecting the VU meters to your DAW in order the show volumes of different tracks? Or is it a completely different application without using a DAW at all?
When it's indeed a solution for a DAW, you need some tool to convert the amplitude values of the MIDI tracks to MIDI messages, like Blue Cat's DP Meter Pro.
With my comments and test above, I just wanted a way to verify whether the plug-in is actually sending data.
I'm not into DAW software so I can't really advice you on a better or different way.

Thanks for mentioning our project here!

Paul's suggestion is indeed a great way to debug and find out where the issue comes from. You will have to double check every single step of the whole process to find out the issue.
